Selection Test Description
Norm
Any test modes or loopbacks are cleared, and the unit is placed back into an
operational state.
Bypass
The downlink signal is sent out to the demod with the CnC canceller disabled. This
is useful for checking integrity of inbound link; however, the outbound modulator
must be turned off.
Uplink
The uplink carrier is sent back to the near end demodulator. This test mode can be
used to close an external RF loop on the near-end modem.
CW A pure carrier (no modulation) is transmitted out the remodulator.
1010
An alternating 1010 pattern is sent to the remodulator. This test mode is used for
checking the carrier suppression of the mixers.
If the user selects LampTest, a visual test is conducted on the front panel display and LEDs to
verify that they are operational.
