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
Wide Offset
Enter the generator frequency offset relative to
the monitor frequency entered. Offset frequen-
cies 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
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
description for further details.
NOTE
Only FM modulation is provided for the du-
plex generator. Either FM or AM
demodulation may be selected. Selection must
be done in MONITOR Mode within the RF
control zone. The RF I/O port combines moni-
tor and generate signals for the duplex func-
tion. However, either the ANT or GEN ports
may be independently selected.
