If you use this gadget a lot you will want to pick up a pair of SMA male-to-female couplers and attach them permanently to the unit to serve as connector savers. They will be a lot easier to replace when they are worn out than the connectors soldered to the board. Keep that lovely TR7 lit up man! - NU0C
TNX, just bought one and after going thru the specs I went to YT to find out more. Glad of your video, because I had more questions! You solved almost all my questions and when this widget gets delivered - the fun begins !!
Good video. Thanks for posting. The TinySA Ultra also has an input step attenuator (30 dB). I would find a plain English discussion of that feature helpful. 73
Hey Seven Forty, Laura here, I just wanted to let you know that a piece of flat black project board, opposite your camera, and placed at about a 45 degree angle just off camera, and below your lights will eliminate any unwanted glare from studio lights. You may have to play around with positioning, but I promise you it will work. The object is to create a "reflection" of the black card on the screen of whatever you are reviewing, instead of the distracting lights and surroundings, so the audience does not see the lights, and etc in the display. The next way is to remember that the angle of attack, is equal to the angle of incidence. So if you make sure your camera is away from the reflection of the light, but dim the lights in the rest of the room, you should not see any reflections in your displays when you video them for RUclips. Good luck sweetie, and I hope that works for you. Laura.
Thanks for the tips! My shop lighting isn't really set up for video so the black card trick may work to help diffuse the overhead lighting to the camera. I tried playing with turning lights off but the screen on this device was really reflective and I was getting glare from every light source in the room. Changing the camera angle limited some of it but made the screen difficult to read so I made the best compromise I could and went ahead with the video.
Nice job! I like my ultra and use it with the PC software almost all the time. I finalize things in serious work with my Siglent SA unless the freq range is above the Siglent. I also bought the TinyPFA phase analyzer. Great companion tool!
A little advice, NEVER screw a connector together by spinning the female (in this case, spinning your radio like you did @ 15:00 into your video) onto the sma - N adapter. You should ALWAYS spin the "Nut" and keep both connectors still so it pulls the male straight into the female. Spinning the female will eventually damage your connectors. In this video you're running at frequencies that in my work, are considered low frequencies, I worked from 2 Ghz - 70 Ghz which, doing what you did at my frequencies would damage connectors & cables in no time. I had a picture years ago from Hewlett Packard showing damage from spinning female SMA & 3.5 mm connectors showing gouges on the male pin that looked like course threads from spinning the female connector on the male pin, causing amplitude & phase errors.
Thanks for another excellent video. I just purchased a TinySA (2.5” screen because I am cheap). My main purpose is to have a portable spectrum analyzer to take to the Solar shop here in Texas. I want to see what trouble some of the components will cause my radios. For instance anything that changes state like a MPPT or a micro inverter or a DC Optimizer. I am eager to try out some DC to DC converters with this analyzer. My next step will be to setup a poor mans yagi for like a fox hunt application to know where the interferes are or in what direction. I do know some of the solar controllers we use in portable radio ops have noisy or RF silent operation. I just want to prove that for myself. Thanks again for your video. I am from the Electrical Engineering background, but never touched radios in my career so it is fun for me to put connectors on LMR400 (well fun??) or tun my own HF dipoles. Thanks for listening. All the best from north Texas. 73 de KI5HXM!
Thanks for the video; there's a lot more to uncover, but you got me over some humps and able to make use of the device. And, in a reasonable amount of time.
HI Again, at 14:34 you stated that you had a 5W (~37dBm) Transmitter, and the level shown on the Spectrum is as expected as you have a "40W" Attenuator. I believe you meant to say, you have a "40dB" Attenuator (The wattage of the Attenuator only ensures that the attenuator does not get damaged..., the amount of attenuation will reduce the level of the Transmitter to the safe level on the TinySA)... Details matter..... :)
Am quite an unexperienced user even though I have the DCS marine radio certificate. I like the way you take time to explain what might seems basic to some. You have good pedagogical skills. It´s fascinating to being able to see what we can not see ;) Thanks for your upload.
After calibrating spectrum analyzers for 30 years from many manufacturers it is clearly a slight difference in their user interfaces. The most logical and productive is that from HP-series. If a common menu task is "hidden", you do think of selling the instrument in favour of another unit with a more logically built up menu. If you find the wanted menu item, the technical features on this analyzers is superb though.
Thanks for the review! Starting @14:30, you mention the harmonics are in dBm (0dB=1mW). They're actually in dBc, where they are directly compared to the level of the fundamental frequency. In fact, you can see the scale on the right has moved 0dB to the level of the 'c'arrier, hence dB'c', and all harmonics are measured off this reference. This (to me anyway) is far more useful and I'm quite pleased to see it included in the harmonic measurements.
Nice demo. Not long ago I also purchase this little awesome unit. I don't know what FW version you have, but in any case ver1.4 something from 31Dec24 can even go up to 12GHz! As you said, you don't really use it >HF but still, nice to know it can be used. To be useful one should play with a lower RBW and LNA on, to get the noise down, and nr of points and span not to wait an eternity for 1 sweep 😀
Only what is missing on the unit is maybe a TG (tracking generator). One could do much more with it then, like sweeping the filters, amplifiers and such. I would say Erik @ErikKaashoek go for the tinySA Ultimate in the next edition 🙂 But in any case I am very impressed with this unit so far! Good work 👍
It would be cool if you could show us how to use the TinySA to measure Conducted Emission with a LISN. Great video btw, I ordered a TinySA and you tought me how to use it!
Come back later in the year when the weather gets colder...I'm working on outdoor stuff now but I've got a few ideas for Tiny SA videos when indoor projects start. Thanks for the suggestions!
I am mainly interested in this device as frequency counter while aligning AM radio foe 455 Khz or sweep alignments. Dial calibration of the AM band would be useful and calibrating my service grade. signal generator equipment. I had one a few years ago and found it awkward to use. All responses are welcome here.
Why does everyone only use -40dB attenuators? For best measurement of harmonics in the output of transmitters the input level of the tinySA should aim between -20dBm and -10dBm.
Nice info! Question, i lost my toyota spare key. I presume that key is always sending a tiny signal so the car can see if there is a key in the car. can i use this Tintsa Ultra device to find my key back ?
Excellent video ! It shows exactly how a tinySA Ultra is useful in the shack for most hams. I have both the tinySA & tinySA Ultra, and use the signal generator function the most. For the cost these devices can not be beat. I would love to see a tinySA Ultra with a 7 inch screen. How about it Erik ? 73 Dave WB1COB
Of course they can. Great for the shack or on the bench. I use a computer for service manuals anyhow. I'd still like a larger display so only one device would be needed.@@SevenFortyOne
HI, At 13:50 in, you stated that you were going to enter for the Harmonic span 146.52MHz and you accidentally only typed 146.50MHz. No big deal of course, but just an observation. BTW, Good instruction.
Hi, at 14':29" you have the reading of -3dB for 5W and -40dB attenuation. That is correct, but you already entered the gain of -40dB. Does the unit not automatically account for that and give the expected value of 37dBm directly on the screen?
It's not apples to apples. Look on the left side of the display for "gain" (nothing is shown if it is Zero) and "atten:". They change during this part of the demo.
I wonder if the precision and stability of the tiny sa is up to par to calibrate a receiver... You should also take care of never inject DC and overdrive the input because that will destroy your analyser.
Great job on the video. Very informative and easy to follow. You’re definitely very organized and methodical and the way that you make your videos. By the way, who is CC?
why I bought mine: when the OTA tv industry moved to digital TV back in 2009, TV stations were allowed to keep their channel number that was assigned back when a channel number was assigned to a specific 6 mhz band of frequencies. now, it is just a label. I have a CCTV system. 24 cameras, 4 each, on 6 DVRs. I put the output of these DVRs onto unused analog channels and distribute these through the house via a CATV system from a demolished apartment. problem: you can't tell if a channe; is set on a frequency used by a new user after the OTA channel moved out. The TVs are not capable of demodulating the unfamiliar signaL I use my tiny sa to determine if the anlog channel space is open before I set the channel in my Rf modulator, and avoid the aggravation caused by interference a secondary use is: take it to a truck stop to show CB users the actual effect of tweaking up a CB to put more fire in the wire. show that person that, in reality, there is more power going out, but not in the CB band where it belongs. think about this: do the golden screwdriver guys tell CB users to use bigger fuse, since they are inherently using more DC power to send more RF power?
Hi Rob! Thanks for the excellent demo! I restore old receivers and many require you to sweep the IF to correctly shape the response curve. For example, I want to sweep IFs at 262, 455, 535, 735 kHz +/- 10 kHz. Is this practical with the TinySA spectrum analyzer? Will the device provide/produce the IF frequency +/- 10 kHz while you scan the bandpass shape? Is the display good enough to show the symmetry (or lack thereof) of the IF bandpass profile? Thanks in advance for any comments you have on this! Regards, Fred VE1FA
I have a beloved Drake R8 that needs a fix. It made a nasty buzz and didn't smell well at all. Just wondering if you have any ideas in getting it repaired. Larry C. Thanks.
Is there a way to adjust the gain (sensitivity) to match another unit? Need the noise floor to match. That way I can use this to make scans all over an area, then coordinate several radios on different frequencies for that area. Need the sensitivity of the scans to match those of the receivers.
I know you have other important stuff to do, but can you do a Hallicrafters receiver, say an S-38 ?? Yes, I know that it is a transformers less radio, and am building a similar setup with variac and isolation xfmr with a simple bulb current limiter, what to do when you cannot get old standard incandescent bulbs anymore ??
How did you not blow up the TinySA Ultra when you had the antenna connected and transmitted a signal from the radio? My little TinySA blew up without an antenna connected when I did the same! (normal power, 5w)
Does anyone have an explanation of the 4.4 GHz spike that is shown at 16:47? This is not the high band of the WI-FI router (which would be above 5 GHz). I have seen it in places where there are no 4.4 GHz spike beforehand, then just a 2.4 GHz WI-FI device is turned on. It's as if it is an artefact of the TinySA Ultra, itself. I would dearly like to understand what it is and how it can be removed, if an artifact. Thanks for making this video explainer.
Minus db's don't mean anything to me. If you were to say don't go over a certain voltage or power level I would understand. Please explain and forgive my ignorance.
Right...I didn't show that in the video. I think there are probably other videos that do. I haven't had time to make another video showing extended features yet
@@SevenFortyOne I found a post using it for TV reception alignment. They even mentioned if in a strong signal area, a 10db attenuator might be a good idea. Only thing that sucks a little is that the TV band goes to 870 mHz if I remember and the Tiny goes to 800 in that range - you want 50-900 mHz to cover all the TV bands so you can optimize antenna orientation. If you have to go back and forth between analyzer bands, it sort of defeats the purpose. Might be lucky where bandwidth to cover local channels would fit in the analyzer range.
I don't have my device in front of me but I believe the answer to both of your questions are yes...if you go to the official tinySA website there should be details there on how to do it
Does it have an earphone jack? I ask because I daw one that worked like a scanner if you wanted, then one that you use for learning and testing equipment and such. I asked Josh and he said no for being a scanner. So i am confused. But I am new asf
This has an earphone jack. But...its not really a scanner. It is a piece of test equipment, not a radio. You MAY be able to hear things on it but its not really going to work as scanner for listening to signals over the air
@SevenFortyOne I thought it was also used to visibly see traffic on the airways so you could locate exact frequency or get close enough to check it out?
I'm not really sure but I'm guessing maybe a few hundred feet depending on power levels and antennas used. If you need further range you might want to look into an SDR receiver
I really don't know. If an altimeter radiates a signal a guess you could if you were close enough to it but I'd bet the other instruments in the cockpit might put out signals too
Its a startrex tricorder , its life jim but not as we know it .to be honest i dont know why a reguler joe needs one ! unless you are trying to track a thing down .
The meny composition on this TinySA ultra is not in line with what can be found on most analyzers out there. Not practical at all. Look on HP/Keysight 8590 or 8560 series etc. This composition is very productive. Hope Eric can alter it soon.
I see your point but I'm not sure this device is intended to mimic professional grade analyzers. Everything can be Improved and any improvements will be welcome, but I feel this TinySA is fine as it is considering what it is intended for, it's price point, and the fact that it's not supported by a huge corporation with unlimited resources.
Now this is the video I needed to see after mine arrived ! Thanks 741 !

Hi Rob,
Awesome demo. I bought my SA Ultra from R&L 4/2023. It was $139.95 and still is the same price. Worth the expense. Stay safe. 73 WJ3U
Yep. Got mine from R&L in December. Great value.
Exactly. Support the developer, not the clone copier.
Is the $190 one on Amazon the same?
Good video. Thanks for posting. The TinySA Ultra also has an input step attenuator (30 dB). I would find a plain English discussion of that feature helpful. 73
Thanks for your demo. A purchase soon is the reason your video attracted me and it did not disappoint.
I'm glad you like the video
Very nice overview! Thank you.
Superb introduction to this tiny little marvel. Bought mine yesterday and arriving tomorrow. Thanks for making this video! 😊
Great overview of the TinySA... Among the best if not the best. Hoping you do more! 73, Mike
Thanks for the kind words!

Great demonstration, many thanks

I've been waiting for someone to point that out...
After a spectral reading is done. Is there a button one can click that 'integrates' the entire sweep result - to give an RFI dosage amplitude?
I haven't seen that but maybe it's buried in a menu somewhere
Before using it after an update , use CLEAR Config , solves some problems
Good tip!
Hi, at 14':29" you have the reading of -3dB for 5W and -40dB attenuation. That is correct, but you already entered the gain of -40dB. Does the unit not automatically account for that and give the expected value of 37dBm directly on the screen?

I'm planning to try it at some point but my suspicion is it should be "good enough", at least for older ham and general coverage receivers.
The peak at 432MHz is likely a harmonic of the main CPU clock of 48 MHz (9 * 48 = 432) as stated in the FAQ.

Thx for the video, nice job
Thanks!
How did you not blow up the TinySA Ultra when you had the antenna connected and transmitted a signal from the radio? My little TinySA blew up without an antenna connected when I did the same! (normal power, 5w)
I was using low power on the radio and was quite far away from the tiny SA for that test
The SA does no Fourier transformation. Scanning takes a bit of time, so you must be aware to miss short transmissions (like digital pulses).
This is also an $80 device...it's going to have a few limitations
Does anyone have an explanation of the 4.4 GHz spike that is shown at 16:47? This is not the high band of the WI-FI router (which would be above 5 GHz). I have seen it in places where there are no 4.4 GHz spike beforehand, then just a 2.4 GHz WI-FI device is turned on. It's as if it is an artefact of the TinySA Ultra, itself. I would dearly like to understand what it is and how it can be removed, if an artifact. Thanks for making this video explainer.
SA's are calibrated with a 50 ohm load, short, and open. A SA subtracts artifacts and will show a smooth noise floor after calibration.
Perfect video thx
Can it generat a good enough signal for radio work? Like a s9 signal.
I think I showed that in the video
Minus db's don't mean anything to me.
If you were to say don't go over a certain voltage or power level I would understand.
Please explain and forgive my ignorance.
What is output from the audio jack? Received audio from the strongest signal?
Yes- you are correct. I forgot to show that in the video
hi Chief; in 'ultra-mode' - can we set the SA for smaller 'freq span'?
I think so
Starts at 0 hz, curious. will it sweep at audio frequencies and display the audio on the analyzer?.
I haven't tried that..
Extremely portable🤔😁!
at @3:27 you said this goes up to "even 12 Ghz". but you did not show that off, and it appears to top out at about 5.3 or so? hmm.
Right...I didn't show that in the video. I think there are probably other videos that do. I haven't had time to make another video showing extended features yet
Could I use this to find a hidden GPS tracker on my car or find hidden cameras in my hotel room?
Conceivably...but I've never tried it myself as nobody is tracking me
@@SevenFortyOne You never know. Debt collectors, divorce investigations, grudge from former business partner, criminal opportunist, etc.
Can I use this to aim a TV antenna for best reception? Is unit sensitive enough to detect antenna output?
It might work for that but it's really not it's intended purpose.
@@SevenFortyOne I found a post using it for TV reception alignment. They even mentioned if in a strong signal area, a 10db attenuator might be a good idea.
Only thing that sucks a little is that the TV band goes to 870 mHz if I remember and the Tiny goes to 800 in that range - you want 50-900 mHz to cover all the TV bands so you can optimize antenna orientation. If you have to go back and forth between analyzer bands, it sort of defeats the purpose. Might be lucky where bandwidth to cover local channels would fit in the analyzer range.
@@NoferTrunionsNo worries anymore with TV signals over 800MHz, thanks to the FCC selling off the 700 & 800 MHz bands to cell companies to support 5G.
Hot to get screen from the minature of that video?
One question can you use this to test crystals?
That's a good question....I'll have to try it out
How well does it register pulsed radiation?
I don't really know
Is it possible to export a scan for import into another software?
I don't have my device in front of me but I believe the answer to both of your questions are yes...if you go to the official tinySA website there should be details there on how to do it

Thanks!
Does it have an earphone jack? I ask because I daw one that worked like a scanner if you wanted, then one that you use for learning and testing equipment and such. I asked Josh and he said no for being a scanner. So i am confused. But I am new asf
This has an earphone jack. But...its not really a scanner. It is a piece of test equipment, not a radio. You MAY be able to hear things on it but its not really going to work as scanner for listening to signals over the air
@@SevenFortyOne I will ask the British guy to clarify what he meant. Thanks
@SevenFortyOne I thought it was also used to visibly see traffic on the airways so you could locate exact frequency or get close enough to check it out?
hi i want to collect data from frqeuencies output by walkie talkies from a distance. Do you know how far can TinySA pick up these signals from?
I'm not really sure but I'm guessing maybe a few hundred feet depending on power levels and antennas used. If you need further range you might want to look into an SDR receiver
Can it be used to detect aircraft radar altimeters?
I really don't know. If an altimeter radiates a signal a guess you could if you were close enough to it but I'd bet the other instruments in the cockpit might put out signals too
Great video, many thanks!! Robert K5TPC
👍
if I wass to look at 146.52 what is is the lowest span I can use ?
Not sure why you are asking..
thanks for review 73 from kb2uew
Can the device pick up the frequency of 5 kHz?
@11:49 Pet the dog you monster!!
Did anyone else NOT get a stylus with their unit?
Its a startrex tricorder , its life jim but not as we know it .to be honest i dont know why a reguler joe needs one ! unless you are trying to track a thing down .
This isn't meant to be for everyone...it's a good tool for electronics and radio enthusiasts
Bigfoot sighting @11:48
Generator... Wof wof...
The meny composition on this TinySA ultra is not in line with what can be found on most analyzers out there. Not practical at all. Look on HP/Keysight 8590 or 8560 series etc. This composition is very productive. Hope Eric can alter it soon.
I see your point but I'm not sure this device is intended to mimic professional grade analyzers. Everything can be Improved and any improvements will be welcome, but I feel this TinySA is fine as it is considering what it is intended for, it's price point, and the fact that it's not supported by a huge corporation with unlimited resources.
Nothing wrong with it. vive la difference
Who in the world has the authority to mandate a screen peel?
It was a joke
These the same guys that make good cordless impact wrenches?
And mini chain saws.
Unidentified transmissions in the ham bands are illegal
Correct
Great job, Rob! I have a much better feel for how to use this unit. 73 de WØRHP
741 - of course. Nice tip of the hat to alternative medicine.
Yeah... what?
