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.

[@reps]

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.

[@xDevscom_EE]

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...

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.

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!

Dont get me wrong, I am always excited when a Marco Reps video comes out, but I am still waiting for the wire EDM machine video.

[@firasgh871]

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?

[@stephanbode548]

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 ;)

[@reps]

Is 50 NPLC recommended? I'm not quite sure if I tried with 2002, but I remember getting a lot of noise from Advantest R6581T with higher NPLC settings

[@xDevscom_EE]

@@reps Depends. :) It can be helpful for high resistances, but for DCV I didn't see much difference on my 2002's noise-wise on NPLC 10 vs NPLC50.

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.

It's some off-the-shelf Razer keyboard. its -key is broken :(

[@willkern6]

@@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.

[@DerinTheErkan]

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.

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.
