CAUTION
Do not apply input power to the GEN OUT
port. In the event RF power is inadvertently
applied, the port is protected by an in-line
RF fuse. This fuse may be accessed by
unscrewing the front of the BNC connector
out of the front panel.
13-8.3 DUPLEX
Mode
The DUPLEX Mode (figure 13-12) provides a
simultaneous RF generator output that is offset
in frequency from the monitor center frequency
and fully adjustable in output level.
This capability provides for servicing full
duplex radio equipment as well as repeaters and
radios operating with offset transmit and
receive frequencies. The Display zone provides
softkey selections for Generated or Monitor
clear baseband signal as shown in figure 13-12.
Specific controls which further configure the
DUPLEX mode are located within the RF
Control Zone when DUPLEX is first selected.
The specific entry fields are as follows:
Preset
The preset function is the same as in the
MONITOR mode.
B/W
Selects either wide or narrow bandwidth of
the unit via softkey selection.
Mon Freq
Enter the desired monitor frequency using
keypad or tuning knob.
Offset
Enter the generator frequency offset relative
to the monitor frequency entered. Offset fre-
quencies of –999.99975 to +999.99975 MHz
are allowed, but the final generate frequency
will be constrained to 000.40000 MHz
through 999.99995 MHz. The offset
frequency is set in 2.5 kHz steps.
Mon
This field actually contains two separate
fields, one for monitor input attenuation and
one for monitor port selection. Refer to the
MONITOR mode description for further
details.
Gen
This field actually contains two separate
fields, one for generate output level and one
for generate output port selection. Refer to
the GENERATE mode description for further
details.
