[time-nuts] HP 8924C's on ebay

[Jeff Mock]

Hmm, good points.  Here's the 8924C datasheet:
    http://cp.literature.agilent.com/litweb/pdf/5968-4094E.pdf

I'm not sure about all of the variants for TDMA and GSM and such, but it 
seems that some are better than others.  It looks like the 8924C 
supports full bandwidth sweeps of the spectrum analyzer.  It does look 
like the RF generator really can be used as a tracking generator but 
maybe I'm reading the datasheet wrong.

The narrowest RBW of the spectrum analyzer is only 300Hz, which is a 
little limiting.

I think that I'm not inclined to get one, 60-pounds...
