8.3.1
Setting the AGC Threshold
The OceanTRx
TM
4-500 system is supplied from the factory with noise-floor correction
calibrated and activated. AGC values are set to a constant value of -75dBm.
If for some reason noise-floor correction is deactivated, or the operator wants to
introduce a user-defined threshold, the threshold level can be set manually.
See Section
on page 8-29 for information on setting
the AGC threshold.
