[Premium-Rx] A question about R&S EZM Spectrum Monitor

[Marvel_63 Marvel_63]

Hello, Spencer!
I read your message on
http://www.qth.net/pipermail/premium-rx/2012q3/007198.html I have a EZM
Spectrum Monitor. I'm not quite sure, but it seems to me that this device has
a high-stability reference oscillator. Is it really? Where is it and how you
can adjust its frequency? I don't have service manual and operating manual
for EZM...
