Figure 4-5. IF Loopback
Note:
When IF loopback is turned on, the demodulator is looped back to the modulator inside the modem and the demodulator is
programmed to the same frequency as the modulator. This test mode will verify the operation of the modem. When IF loopback is turned off,
the demodulator is programmed back to the previous frequency and is reconnected to the IF input.

BER THRESHOLD
BER THRESHOLD
NONE
Sets the BER threshold. If the BER threshold set is exceeded, a receive fault will be indicated by
the modem status indicators. BER threshold may be set from 1.0 E-3 to 1.0 E-8, or may be
disabled by specifying NONE.
Upon entry, the current setting of the BER threshold is displayed. Press [
↑] or [↓] to select the
desired setting. Press
