Very nice overview of the Model 2002. After years of making DMMs with 8-bit microprocessors and being limited to a 64 kbyte address space, designing the Model 2001 and 2002 with a Motorola 68K-based processor allowed us to pack them with features. It also allowed for use of the SCPI GPIB commands instead of the previous generation "R2D2" command set (as we used to call it). This is what Marco alluded to with the Model 237. And yes, our analog design team was world class.
Hm, this commenters name looks familiar somehow 🔍 04:12 Wow, so glad you liked it! I didn't have a whole lot of time with this demo device, but I'm still hoping to snatch one on eBay one day for a closer look and some tinkering.
Nice to see you here, and thank you for your work. 30 years later, and there is still no competition to 2002 in half-rack formfactor. Only sad to see that it's full potential was not utilized like proper support for Keithley 1801, resistance and phase-measurement cards, etc. ;)
@@reps These instruments are like Kwantum Mechanics. 😂 If possible I'd like to see you cover the DIY build of a digital controlled power supply. Preverably with linked outputs to power precise op amps. My Keysight E36312A is driving me crazy. There seems to be no way to adjust the values linear. Being Volt or Ampere... Any tips on how to properly calibrate this?
You know a serious volt-nut when the calibration dates are treated as the absolute and sacred demarcation lines between reliable and a rough estimate that they are. It gived me such a warm and glowing feeling, and makes my heart frolic with joy.
0:41 Love it!:p Sometimes I wonder, how many of your references have I missed? Maybe you should post a list of references or something for your videos, and we can have some sort of reference bingo!
The "This Old Tony" of electronics strikes again huh? Thank you so much for the uploads Marco, finally have something to watch again while I'm working where I can learn myself something new
Sometimes you can find a cheap ICS GPIB LAN gateway on ebay - found these to be good value and easy to work with. I used Grafana for work all the time and never had the idea to use it for logging mulitmeter output! Thanks for that! Finally there are a bunch of projects that abstract electronics instrument controls. I've been looking at InstrumentKit and PyMeasure amongst others. Worth adding to an existing library rather than building your own!
The (relatively) cheap ProLogix GPIB-Ethernet dongle can go a long way too. It has some annoyances because of the very low end controller and lazy design, but for most applications it should be fine.
Pro tip: When stacking test equipment 3, 4, or more levels high, it's recommended to spread mortar between the levels to equally distribute the weight downwards.
Perhaps the Keithley 2002 is super precise and has very low error count, but freeze frame @7:05 and you can spot a spelling mistake in the word "measurement" on the display. Perhaps it could be mentioned to Tektronix?
This is cool again. This pico voltage measurement is fascinating & crazy. Temperature measurement with thermocouples is critical, because thermo voltages at the connections. It is always better to use PT100/1000 resistors in a 4 wire installation.
Linearity test is not linear enough, it's more of tiltalarity in the plot. :P It's cool that they've added Wayne Goeke to this new K2002 team list. He is the one who designed 3458A's magical ADC and now works for Keithley ;). Hint for future : RJ45 cable is good for nanovolts for DCV measurements, but not good for resistance as its isolation is not that good. For high-ohm resistance best to use gray-beard approved PTFE-insulated cables. As of NPLC, K2001 have max 10 NPLC, while 2002 can do 50 NPLC ;)
Nobody needs them nanovolts, but when when the volt-nut bug bites there's no rescue. It starts innocently with handheld dmm's. Then the volt-nut bitten discovers eBay, and it's all downhill from there. They usually ends up as graybeard virgins in national cal labs, fighting for grants for trips to bipm or nist.
I really don't understand GPIB interface prices. It seems the cheapest interfaces are basically a GPIB connector with some free electronics in terms of BOM cost, and then the price starts going up from there with no end in sight.
The fake NI ones for around 100 bucks work well enough for me. Original NI ones are made much nicer and they can be faster if needed I think, thanks to their custom ASIC
Thanks for the clarification . My question in the video clip 5.57 is the two devices of the same model number Keithley 2002. And since you mentioned previously, the accuracy reaches the nanovolt, assuming the two devices are of the same version, why is the difference in reading the 10 volt?
I like the recess shrouded banana Jacks I made a little box of myself that had a selection of The Binding post and other connectors I can easily plug in If I need it
I see Keithly, I see meme man, it will be a great video... PS: you should check some GDR measurement equipent, I own a few präcitronic devices, they are built rather well. Robotron also made some great devices, at least when you consider how bad the GDR economy was. Of course nothing compared to Keithly, Agilent etc.
Sure, your metrology tech is pretty cool, but I just want to know what kind of switches you are using on your clicky keyboard with the RasPad. They sound like Kailh "box" clickbar switches, but I might be wrong.
@@reps Aha! Razer green switches are also click bar switches so the similar sound makes sense. If you need to repair the -key, I don't know if you can buy individual razer switches but Kailh (Kaihua) makes a bunch of very good clickbar switches. The closest replacement for a razer green would probably be a Kailh Box White, but there are also many other options with heavier springs and thicker clickbars if you wanted to build your own custom keyboard. Also, if you ever did decide to make a custom keyboard, please be sure to make a video ;D EDIT: I just looked it up and I was wrong about the internals of the Razer switches - they ARE made by Kaihua, but they have a different mechanism than the other ones made by Kaihua. Also still no luck on finding replacement Razer switches. I think they only come in complete keyboards.
Hi! At first I want to say that I realy enjoy watching your videos and content. The second thing on my list is a question: do you know where I can get such Solartron input cables? I got an 7075 cheap on eBay, but it apparently came without the input leads... A quick search on the internet told me that it has a special Fisher connector. I didn't asked there customer service, but I believe an original replacement part would cost me a fortune, so I'm curious where you got yous or if you know where i could possibly get one. Thanks!
Everybody who has a 10V, a 10kOhm and a 1Ohm reference can. Guess why I'm looking so hard for a 1 ohm reference :) F5700A wants to know the absolute values of these references to adjust itself to them. Those 3 external references in turn should be calibrated by something even more trustworthy, for example national metrology institutes like the PTB
@@Zertrebender Of course there will be videos about the holy trinity of external references. For 10V I already have a Fluke 732A here. For 10kOhm I have purchased a bunch of crusty 40kOhm VHP101 from questionable sources. I'll measure their temperature coefficient with Arroyo and select the 4 best ones to make a somewhat good 10kOhm reference. ESI SR104 would of course be preferred, but you can probably buy a Keithley 2002 for the price of that one 10k resistor :) 1 Ohm is difficult.
@@reps looking forward to that video, I love high precision stuff, the feeling of moving 4Tons of X axis in my company with literally a thumb is just to fucking nice
@@reps @Marco Reps I have a few weird looking large 1 Ohm resistors that came with calibration notes in a plastic box. Don't know if they're what you're looking for but they came from a Phillips/NXP lab in the Netherlands, so you know they're not the worst quality. Let me know if you want to have a look! (If I remember correctly they're five precision film resistors with 0.1% tolerance made by Caddock)
I sometimes really scratch my head where the hell do electronics youtubers get such expensive equipment from, does youtube really pay that well Like oh look at this cool test gear piece, **looks up on ebay** oh it costs like a new car, ok
I grew up with Fluke Calibration Equipment, 335D, 332A, 5100B, 5101B, 5102B, 5200A, 5440B, 5700A Fluke Calibration Equipment is very well made, Fluke early Calibration Equipment before 5700A is quite easy, not that many specialised components, 5700A you did very well getting that given to you, pity about that burnt PCB, but I suppose if one wanted, you could get a PCB manufacturer to make another for you, Vishay make specialised resistance networks, if any are on there way out, Caddock also make resistance networks, what I will say I do hope Fluke supply a proper service manual for the NEW range of Calibration equipment, not just a block diagram & PCB change, that to me would be off-putting, Again you did a very good job, those Components must have cost a lot of money 💰, but in the end you have a Very Good Fluke 5700A Calibrator that will no doubt last another 30 years 👍 👏
I don't understand why that GPIB to Ethernet converter has an FPGA on it...any decent microcontroller with ethernet should be enough. Unless there is some advanced functionality I'm missing (like being able to put your own bitstreams on the FPGA)
Maybe bandwidth. And the ease of changing the circuitry/updating functionality for a ton of existing devices. The fact this thing isn't produced anymore reminds me of an unsuccessful prototype. Just speculation. AND I WANT ONE, TOO! hehe:) Found a similar device: www.antratek.de/prologix-gpib-ethernet-controller prologix.biz/gpib-ethernet-controller.html Have a look at the FAQ and PDF manual. It may answer some questions.

Hello brother, I just bought a Rofin Sinar Diode Laser Dilas M1F2S22-976.2-130C-IS34.2MO but I don’t know what is the best power supply to run it, and I didn’t find anyone else interested in the field, so can you help me in choosing the power supply
I think 2002 and 2001 have pretty much identical cooling setup. The only difference I see is a small shroud thingy. Maybe that allowed them to use a slower, quieter fan.
I have seen some Arduino-GPIB projects around, there are several in github actually. if you are not expecting to do fast acquisitions, probably they would do the trick. I did not test any so far.
I did not understand, whether you already calibrated the 5700, or just rely on the original status. The 5700 and the 2002 agree within a few ppm in DCV, but disagree in DCI, that indicates, that OHM (10k at least) was not calibrated on the 5700.
Yep, you are right, I didn't make that clear: I did a manual range adjustment for the F5700A 10V range based on K2002. Same for the two other voltmeters involved. I didn't adjust all the functions and ranges, because I might already have a better calibration within reach.
MARCO....I’m sure you’ll do a more extensive explanation of the Banggood lcr meter you have there… But for a quick review… Is it a good one or bad one? Just curious. Lots of times I want to use lcr meter in a “sketchy“ situation.... but I’m afraid of damaging it. it’s a high-end HP model and I would love to have a cheap one under in case I blow it up 😂 I don’t understand all of the electronics theory as well as you do… So it’s always a risk with me that I might blow something up. That’s why I have my fancy gear… for when I’m asked to do something extremely thought out and detailed for a special client. Then I have a secondary set (or two sets or three)…of gear that is still extremely good and serviceable just not too expensive. Like The Agilent/HP 34401a is a great meter but I’m not afraid of using it like I am some of my nicer meters.
They are alright for general usage, they will crap out when you go to extremely high/low component values but that's what the expensive big boy toys are for
Marco is great because I didn't understand a thing but still watched it until the end.
me too, the only thing i know is it has something to do with multimeter or something with electricity stuff.
Exactly haha
Hmmm yes I know some of those words
Same here,,,
It seems to run on some form of electricity!

Do you get to keep that keithley? That’s quite a hefty pay day for just one sponsored video. Congrats on that!
Why do I always Think of him when I make the tool control and see a Biegelehre in the Workshop at my Scholl ;)
HOW DO U MAKE THOSE SIMULATIONS!!!!!
What software were you using for your simulation please?
I think he is using the one at www.falstad.com/circuit/
Отличное видео! Ни одного дизлайка.
What another video already, well thats a like already! PS: and it was informative, to bad I cant double like!
10:43 Marco, what the hell is this?
I did not understand, whether you already calibrated the 5700, or just rely on the original status. The 5700 and the 2002 agree within a few ppm in DCV, but disagree in DCI, that indicates, that OHM (10k at least) was not calibrated on the 5700.
Yep, you are right, I didn't make that clear: I did a manual range adjustment for the F5700A 10V range based on K2002. Same for the two other voltmeters involved. I didn't adjust all the functions and ranges, because I might already have a better calibration within reach.
what?
Marco uploading two days in a row?
What is this sorcery?
Grafana + InfluxDB + Telegraf =
MARCO....I’m sure you’ll do a more extensive explanation of the Banggood lcr meter you have there… But for a quick review… Is it a good one or bad one? Just curious. Lots of times I want to use lcr meter in a “sketchy“ situation.... but I’m afraid of damaging it. it’s a high-end HP model and I would love to have a cheap one under in case I blow it up 😂
I don’t understand all of the electronics theory as well as you do… So it’s always a risk with me that I might blow something up. That’s why I have my fancy gear… for when I’m asked to do something extremely thought out and detailed for a special client. Then I have a secondary set (or two sets or three)…of gear that is still extremely good and serviceable just not too expensive.
Like The Agilent/HP 34401a is a great meter but I’m not afraid of using it like I am some of my nicer meters.
They are alright for general usage, they will crap out when you go to extremely high/low component values but that's what the expensive big boy toys are for
2 videos in one quarter?
I am here because i like power and precision electronics :)
Two videos with only a day in between? What is going on?
