Figure 17-11. Monitor Mode - RF Zone
The specific entry fields are as follows.
Preset
The preset entry field provides a convenient
way to enter a bandwidth, frequency, and
other information for the unit by recalling
preset data from nonvolatile memory. If a
preset is not to be used, enter the desired
information at each of the fields.
NOTE
If a preset had been selected and changes
are made to any of the preset values, the
"Preset:" field will have dashes through it,
indicating the preset is no longer selected.
B/W
Selects either wide or narrow IF bandwidth
of the unit via softkey selection.
Freq
Enter the desired monitor frequency using
keypad or TUNING knob.
Attenuation
Selects the amount of attenuation at the RF
input to the monitor receiver using softkeys.
Selectable input attenuation is useful in
adjusting displays for a wide range of input
levels, as well as for use in high RF field
environments where intermodulation may
cause desensitization of the receiver.
Mon RF In
Selects the RF input port via softkeys. The
RF I/O port contains an RF load and should
be used for direct connection to the radio
under test. The ANT port accesses the unit's
sensitive receiver and should be used with an
antenna for "off-the-air" reception. Selection
of the ANT port is indicated by a red LED
next to the ANT connector.
