  1. Dear Neil Pate Thank you Very much for your answer. When I am trying with Set current vi for single current setting, it works fine. Even the instrument is working well, as I can sweep manually in nano range..... Here with i am attaching the snapshot of front panel. Is the front panel parameter adjustments are correct? Is there any changes are required? Snap shot of Front Panel.doc
  2. I am interfacing Keithley 6220 current source by Labveiw 8.6 through GPIB bus and KUSB 488A. I am using example VI which is provided with Keithley drivers for current sweep. I don’t have any problem in sweeping the current in micro or milliamps. But when try to sweep in nanoampere (even the step level in nanoampere), it shows error message “-222” which stands for “Parameter data out of range”. Can anybody please help me to resolve this error to sweep in nanoampere (stop level as well as step level in nA). I am herewith attaching the the VI which I am using. Front Panel during run (which shows my controls) and the error message are also been attached. Thanks in advance Front panel.doc KE622x -- Execute Current Sweep Example.vi
