trigger voltages (pulse or AC waveform) and record currents simultaneously with 2612B

Good evening,

I post a new thread to have please more details in order to trigger voltages (pulse or AC waveform) and record currents simultaneously.

1) I apply a sinusoidal voltage signal to the smuB with a Keithley 2612B (please see attached TSP script).
In the same time, I would like to polarize a constant voltage to smuA and record the current (please see enclosed the schematic).
But I cannot recover the current from smu A with the 'printbuffer' (see attached TSP script).
I must be wrong about the addressing of the 'buffer'? (or something else?) Should I also 'trigger' smu A?
Can you help me to unblock this please?

2) Moreover, I would like to apply a frequency of up to 100 kHz. I have an AFG1022 signal generator (Tektronix) to apply the sinusoidal voltage (i.e replacing smuB).
But how to do the setup? and the connections to setup to the DUT? Should it be synchronized with the 2612B? or the computer control (i.e Python) should be enough to synchronize the 2 instruments? (for info, I drive the AFG1022 by computer but cannot successfully record the i,v parameters...)
Could you also please guide me on these aspects of instrumentation development?

Thanking you very much for your time and support.

Best regards,

Sébastien
