Setup:
-My app controls one Power Supply and sets a static voltage for testing (simple & basic).
Problem:
-I have one particular user (out of thousands) whose PS is taking nearly 4 sec. to turn on once the GPIB command is sent (yes, I actually use a timer and A->D to check).
Q:
-Any ideas why this might be happening?
-Any ideas for debugging?
HW:
-National Instruments GPIB-USB-HS
-Agilent E3642A power supply
SW:
-Lasted NI488 drivers from NI
-My custom App (which I can provide an exe example of).
