RF In/Ant
This field selects the input port for the spectrum analyzer.
Operating Considerations
Maximum signal levels are printed on the connector panel.
CAUTION Connecting a signal of >60 mW to the ANT IN port can
cause instrument damage (although internal protection
circuits can typically withstand a short-duration signal of
several Watts).
If the overpower circuit is triggered (signified by a
warning message at the top of the screen), remove the
signal from the ANT IN port, and reset using
Meas Reset
(press and release the Shift key, then the Hold key) or turn
the Test Set off and on to reset it.
Using the ANT IN port with the Sensitivity field set to High can
result in uncalibrated operation (a message appears on the screen when
this happens). The purpose for the high sensitivity setting is to allow
you to look and listen to very low level signals when absolute accuracy
is not essential.
See the "Sensitivity (spectrum analyzer)" field on page 150 for more
information.
