Description
The Spectrum Analyzer Port menu selects the input connector
for analyzing incoming signals.
ANT/SWR
ANT/SWR should be selected to perform over the air testing
using an external antenna or when test parameters require
maximum input sensitivity. The ANT/SWR connector
should be used when analyzing low level RF signals.
DUPLEX
DUPLEX should be used when analyzing high power RF
signals. The DUPLEX connector is a combined (Duplexed)
connector that provides an RF Gen output connection and
an RF Receiver input connection.
Resolution Bandwidth (RBW)
RBW filters are the bandpass filters in the IF path that
determine the RF Noise floor and how close two signals can
be and still be viewed separately on the analyzer.
A narrower RBW setting more clearly displays close signals
as separate signals; a narrower bandwidth setting results in
a longer sweep time.
An RBW setting that is too wide causes signals that are
close together to appear as one signal.
Auto: system sets RBW to a filter appropriate to the
characteristics identified in the received signal
Manual: allows the user to manually define the RBW.
