This code has worked for me for years, but is incompatible with the new Keithley 2600 Series driver.
I've tried to port it all over, but the "Channel" control seems to be missing.
Could you help me to rebuild this with the new instrument driver?
New driver? Is it on NI page or Tektronix? I'll have a look tomorrow. I suspect they probably just renamed the control type def. for the channel and it should be an easy fix.
