[Test-Equipment] HP 8673M 2-18GHz generator problem

Tue, 20 Jan 2004 07:00:35 -0800

How's the YTO's FM coil continuity?

How's the output of the sampling-type detectector (phase gate) used to
sample the YTO output?

These things aren't usually too hard to troubleshoot if you have a manual;
nearly impossible otherwise.
