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?

73/
