Hi All,
I am at wit's end trying to debug an intermittent timeout in GPIB communications in a system involving a wafer prober and and Keithley 237 source-measure instrument. System is a basic Step-Measure-Step-Measure architecture where both instruments are VISA/GPIB controlled.
Measurement process involves thousands+ steps and each step can take in the 3-6 seconds range, making a single measurement process last a few hours.
Timeouts occur intermittently after minutes or hours of stepping.
Each instrument has it's own LV class and a wrapper class is used to time communication over the USB GPIB cable.
Any suggestions on how to attack this issue?
