flaky thru calibration

Question asked by andrewrt on Feb 2, 2007

I'm using Wincal 3.1 on HP8720ES VNA and everytime i go through the 'thru' calibration, it seldom completes the whole 'thru' calibration, because the VNA stuck after some frequency sweep.

is there any idea how to resolve this flakyness. I tried power-cycling the VNA and the GPIB box, but this still happens over time.
