Subject: LF: HP3586A advice?
Gentlemen,
A HP3586A selective level meter recently
followed me home, but without any documentation.
I intend to use it as the basis for
precision
LF/MF/HF off-air frequency measurement
applications,
and I wonder if the combined wisdom of this
reflector could help with a few questions about this
equipment:
1. In the selective level or SSB carrier
measuring mode,the IF resulting from the incoming signal is
translated to an audio baseband with the help
of a BFO giving a 1850 Hz beat tone. It
appears to me that the BFO is not phase-locked to the reference oscillator.
Can anyone confirm this
assumption?
2. There is a function labeled "counter" that
supposedly enables the user to measure a signal frequency within the IF
passband of the
HP3586A. Is this correct, and how is this
function enabled in operation?
