to
Functional Check
on page 1--14 for using the cal signal to check the
system performance.
Reference Source. Selects the source for reference frequency.
H
Int.
Uses the internal clock (10 MHz simulated sine wave).
H
Ext. Uses the 10 MHz sine wave of --10 to +6 dBm from the REF IN
connector on the rear panel when you want to synchronize the analyzer with
other instrument(s).
The reference clock is available from the REF OUT connector on the rear panel.
