I cant be bothered to look at the manual as it it out of reach, but has it
occured that you are assuming that the marker and RF output are
connected......they may not be. Check you actually have a RF output on a
scope or an RF voltmeter. The marker could be generated from the scan and
the RF signal could get lost before the counter take-off and the output
terminal. Like all fault finding you need to go round the loop checking for
signals with an independent piece of gear. Dont just make assumptions about
how it works. Things that "must" be working usually arn't from my
experience, until proved otherwise !!

Subject: RE: [hp_agilent_equipment] Re: HP-8443A Tracking Generator Problems
Since I have demonstrated the counter portion of the 8443A is functional
as
it will count an external signal from my signal generator and the RF
output
the 8443A is functional
NO not necessarily....measure it !
since there is a marker on the CRT display, the
problem is in the counting of RF output frequency at the point where the
scan is stopped to generate the marker.
If I am still off base, HELP.
