Please turn off "Stable Volume" in the video playback setting (the first menu item after clicking the gear icon) as for some reason, this new RUclips playback feature made the video much noisier than usual.
The two frequency counter readings are from different methods, one is likely a hardware frequency counter that requires a decent signal level to be able to detect it, if you tried increasing the input level it probably would have detected higher than 100MHz, the other one is purely a measurement from the waveform itself, if the timebase is set too fast limiting the number of cycles on the screen (or in memory) that counter will not be able to count correctly either.
Thanks for this video.I just buy one. The fan functionning is quite strange : 10 seconds it is ON functionning at high speed, the following 10 seconds it is OFF. I expect a better regulation of the fan speed. Do you have the same issue? I precise, this behaviour is without measuring any signal on the scope.
It seems like an incredible oscilloscope. A bit slow to start and very expensive, but it seems very good. I have a question because I’m still looking for a device with high sensitivity. What is the minimum value of V/division it supports, 5mv/division?
Looks like you got a screenprotector for the older model with knobs, as that unit is a tad longer screen, and a tad shorfter in hight, but only like ½ cm. as the older model do come with a mattscreenprotector incl. the bootup time seems to be the same as the older model, if I recall was around 35 sec to scope interface, and around 20 to 25 sec to UI homescreen, though after installing soem of the apps and this office program where you log your values on the fly in excel and all that jazz, the bootup time become slower and up around. 40 to 45 sec before scope interface ready. a crude fidling with the UI ruclips.net/video/BD6pz_v5pQc/видео.html
Very informative and helpful video. I just purchased this device, and I am amazed at it's performance. Did anyone here tried to use the advanced math option? I can see alot of trigonometry functions, but i don't see what i need, i measure bldc motors with this scope and want to devide frequency with RMS... anyone played with the math there?
Yes, I mentioned in my later teardown video. The display is very easy to read, unfortunately the screen protector made it very difficult to film due to the matte finish.
I built it a years ago (www.kerrywong.com/2013/05/18/avalanche-pulse-generator-build-using-2n3904/). Its rise time is in the hundred ps range. I used a 1GHz bandwidth oscilloscope to test it and it was fast enough to verify the rise time of the 1GHz scope (~400ps rise time).
not sure why Micsig went with joysticks. their clickable rotary knobs was way prefered, for a scope that shall double as a benchscope alongside being mobile those knobs is prefered. (older model 23 buttons 7 knobs, while on new 19 buttons with four 4-way joysticks though the specs, seems to be more or less the same. 1mv div. same as STO-C/E and 1ns peak (1ch) same as C/E the waveform seems to be faster with the claim of 130k vs the older 1000C series, while on the older it peaked at 100.000wfps 100k (example on EEVblog) if its 70Mpts deepth or 30Mpts like the older C-one ruclips.net/video/vDdu-4F3XQs/видео.html does not make any difference, quite the contrary, seem Micsigs is digging a tad to deep for 70Mpts as it seems to slow the scope a lot, though I dont know if that has changed with later updates.. Micsigs two best features IMO, is their manual filtering 30K to 100MHz and their high level-grading with CCT (heatmap), both very nice nd usefull. automated measuring features, no dice, its old school crude cursor approach. personally I aint gonna purchase a Micsig scope again, no way this chinese "Micsig" company is full of bs, with all their promisses & claims about their long living "Android ecosystem" and these new apps & new features, they would roll down and implement and for years kept dangling as a carrot for their STO-C/E series.. and now it seems they are doing their best to destroy older scopes with extremely defects OTA updates, yeah tsk tsk go figure. also worrying how much this Micsig company is greasing social media influencer not least on YT, and nobody of YT techchannels actually put own funds behind this scope
@@KerryWongBlog As i see at 19.30 min, on the scope screen, when you enter to math - points drops to 100k from 1.4M... Sample rate drops to 35.71 MSa/s too.. Is it always the same numbers, or depend frome some settings?
@@Sergey_Onikienko I checked the scope again. So the numbers you saw were for the math channel. Just like other channels, the sampling rate and depth are inversely correlated. The numbers you saw (100k, 3.71Msa/s) were for timebase of 200us. This number changes to (70k, 250MSa/s) when horizontal is set to 20 us. And the sample depth further decreases to 700 with the fastest timebase of 2ns. The maximum sampling rate seems to be at 250MSa/s however. Hope this information helps!
I bought one recently but I'm disappointed because the measurements I'm getting are not correct. It always shows a lower volts in all the measurements I do. very disappointed
@@nikoss4478 I don't have anything that can output 30 dBm, but using my 8642B, I am seeing roughly 0.62V (Vpp) on the Micsig when outputing a 0dBm signal and pretty much the save measurement on my Textronixs 2465 using the same termination method (50 Ohm dummy load on a T). I assume you had verified with a function gen as well? You may want to contact the seller as it could be out of cal based on what you were seeing.

Super helpful ! Extraordinary detail !! I learned lots !!! Thanks !!!!
Nice video. Was hoping to see a teardown as well
The 8-bit resolution is the 'not for me' and shop around. The new 12 and 14 bit scopes are getting very popular. 😎 Anyway, nice video and thanks.
It looks very good! I would like to try one, it's a pity that it is not available in my country
I was reading you don’t get live readings or averages when measuring ?
Nice review but personally I prefer knobs to joysticks !...cheers.
Me too
Thank you. 🥋

Yes, the fan turns on briefly at full speed during power on but in normal operation, it says pretty quiet most of the time.
Thank you Mr. Wong! Excellent presentation as I work on my decision to invest in this tool .. Does anyone know of this STO1004 for less that $800 USD?

for X1 probe, the maximum sensitivity is 1mV/DIV

Micsig STO1004 vs Siglent SDS1104X-E?
Did the UART protocol capture stop because it filled a buffer that you could then scroll through to examine it?
I think it's a software bug as you can see after I went to the trigger menu without changing anything the capture resumed.
Hi, would you take a look at ANENG Q10 DMM? TIA
Hopefully the actual o'scope display is sharper and easier to read than on this video.
Yes, I mentioned in my later teardown video. The display is very easy to read, unfortunately the screen protector made it very difficult to film due to the matte finish.
I’ve been trying to get Micsig to send me one of those to look at, but so far they have been ignoring me!
Hi, we sent you email, please check.
@@MicsigOscilloscope thank you, I have replied to it.
Hi, I will send you one from my company☺
What are you using for the avalanche pulse generator and what is its rise time?
I built it a years ago (www.kerrywong.com/2013/05/18/avalanche-pulse-generator-build-using-2n3904/). Its rise time is in the hundred ps range. I used a 1GHz bandwidth oscilloscope to test it and it was fast enough to verify the rise time of the 1GHz scope (~400ps rise time).
@@KerryWongBlog Nice! Thank you. It looks like the pulse is about 25V pk-pk. That makes for a pretty amazing slew rate.

Could you provide an example (waveform, frequency, etc.) ? I can check on mine to see if I can reproduce.

when I measure until 200nS the measurements are correct. when I measure 100nS and less the measurements are not correct. see the table above
@@KerryWongBlog i think it's a software problem
its a bit noisy
Maybe you could review the newer Micsig TO1004 (all virtual controls)?
