keithley 6221 & 2182A KI622x.vi block diagram

Does anyone has the block diagram for KI622x.vi .  I want to edit the program and make it convenient to me, as I suppose with my limited labview knowledge it will take more time if I strat from scratch. I feel people have written some program like KI622x.vi and I will be very thankful if they can share it here. Unfortunaltely keithley engineers are strongly committed not to provide the block diagramSmiley Mad

Keithley provides an IVI driver. Use the class driver or create a LabVIEW wrapper with the import wizard.

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.
