Identifies the port to which this setup menu applies.
B
FREQ 71.00
.

.
129.00
Sets the RF output frequency in MHz. Scroll through the list of supported
frequencies from 71.00 through 129.00 MHz.
C
LEVEL 1
.
35
.
40
Sets the RF output signal level. The scale from 1 through 40 corresponds to
an output signal level range from +30 dBmV t50 dBmV.
D
UP
Displays the MAIN menu.
E
MODE OPERATE
STANDBY
REV TEST
CON TEST
2T TEST
CW TEST
Sets RF modulator function. Scroll through the list of supported modes:
OPERATE enables receipt of packets from the multiplexer and
transmission of QPSK-modulated output.
STANDBY disables both receipt of packets from the multiplexer and
transmission of a QPSK-modulated output.
REV TEST enables both receipt of packets from the multiplexer and
transmission of a QPSK-modulated output with reversed I and Q
channels.
CON TEST enables both receipt of packets from the multiplexer and
transmission of a QPSK-modulated output with modified digital filter
coefficients.
2T TEST disables receipt of packets from the multiplexer and enables
transmission of a two-tone test signal.
CW TEST disables receipt of packets from the multiplexer and enables
generation and transmission of a CW carrier.
In general, the test modes are reserved for factory testing; however, some
are useful for troubleshooting specific equipment faults. Refer to Section 5,
"Troubleshooting," for more information on modulator test modes.
