Add a Notify block to your trigger model, described on page 8-32 of the 2450 Reference Manual: https://www.tek.com/en/keithley-source-measure-units/keithley-smu-2400-series-sourcemeter-manual/model-2450-interactive-sou

The smu.source.sweeplinear() function simply creates a trigger model that you're free to edit after it's created. If you're doing this programmatically (it sounds like it) you will need to edit the block numbers of all the blocks that come after wherever you insert the Notify block. I would recommend trying this from the front panel first so you can use the display to get a better idea of the trigger flow, you can also use trigger.model.getblocklist() to see the whole trigger model via a remote interface.

Hello, sorry but we won't share schematics for those products. If you are able to localize the problem and share specific info on what's wrong we might be able to provide guidance, but perhaps not.

The 2306 is able to be repaired by us should you want it done professionally: https://www.tek.com/en/services/select-factory-service-request

For a few calibration procedures, a 2450-CAL-KIT accessory is required. This is accessory is not sold anymore, but it is simple to create, here's an FAQ that describes the fixture: https://www.tek.com/en/support/faqs/what-is-the-2450-cal-kit

Another question we frequently get with 2450 calibrations is if you can use the front panel. The front panel can be used for performance verification, but for making adjustments, the rear panel must be used.

I'm not sure why it's missing from the website, I've raised the issue, but here's the 2450 Calibration Manual.

Now that is very odd... that's the correct URL. I will send this to our web team.

Can you share any of those broken links?

Select the "Software License Options" tab, then you can select the App/Apps you want (I would guess Data Logger for your DAQ6510). Use Add to Quote and you'll be able to get a quote from there.

Hmm, there is not a command to get arbitrary text on the front panel of the 2635B. As you found, display.gettext() is only for the user screen set by display.settext(). Things like measurements, source values, and settings are meant to retrieved with their own commands. That is probably better for a remote display anyway so you can always poll important parameters rather than relying on what the 2-line display shows.

Oh good! I had read through your post but hadn't looked at the code yet. Glad you figured it out! Autozero is a very common setting to trip people up when trying to do time dependent measurements.

We do recommend using the Autozero Once command (AZER:ONCE) immediately before your test and periodically or when you have gaps in your test for the best accuracy.

How many voltage points are we talking about?

My first thought is to try sending the list to the SMU separately as new array, breaking it up if needed. In pseudocode:

writeline(K2412B, strjoin({'vlist=',VliststrPart1)});
writeline(K2412B, strjoin({'vlist=vlist..',VliststrPart2)});
writeline(K2612B, strjoin({gate_smu,'.trigger.source.listv(vlist)'}));

(".." is the concatenation function in TSP/Lua.)
