I am having problem in programming Keithley 6221-2812A regarding the following
(1) Making staircase sweep and read and save data of the resistance or voltage . 0 to +I to –I to 0 (A complete cycle). Making list sweep and saving data.
(2) How to make Differential conductance sweep a complete cycle. i.e., start from 0 to +I to –I to 0 and make the measurement simultaneously or saving the date in buffer and read it later.
I used the examples provided in the labview drivers for the instruments but it does not work and it gives errors when I try to write the program using them. With staircase sweep, I am not able to save data in the buffer and read it back.
For differential conductance measurements, I could make a complete cycle but after each step(start to stop), the sweep gets aborted and thus the currently abruptly goes to zero. Could you please help regarding this.
