How to Talk to 2400 in ACS

Post by Keith Will » March 8th, 2018, 1:10 pm

I have 3 SMUs connected to my system in ACS (I'm very new to ACS and TSB)
2 are 2612's connected via TSPlink. These show up as "Group1" in the hardware configuration and consist of SMU1, SMU2, SMU3, SMU4. They are on gpib 10
I also have a 2400 connected and it shows up as a standalone instrument on gpib 11

I can talk to the group hardware using the a_smu = node[x].smua snytax, but how do I talk to the 2400?

I am doing this in an STM within ACS

In ACS, the STM object type is only for the Test Script Processor (TSP) products like the 2600, 2600A or 2600B. Also works with switching products like 3706A, 707B.

To access the 2400 on the GPIB bus, use a Python Test Module (PTM). With the access to the GPIB library, you can communicate with any instrument.
There is also a Python library of commands (forcev, limiti, measi, etc.) for control of both 2400 and 26xx based SMU.

NOTE: there is a fairly robust GeneralTest library available to you. Add a PTM to your test tree. Into this PTM, import the Combined_Test_Mixed_SMUs.py library.
This gives you a GUI interface that recognizes all the SMU in your system. It will allow the "mixed SMU" use case.
