Technical Guide: RDMS Telnet and Serial Control Setting the AGC mode to IF forces control of the IF attenuators under AGC control and disables AGC control of the bulk attenuator. This also forces AGC Zero to Auto because when playing back recorded signals, such as demod/playback-demod, the noise floor changes as the AGC in the original recording holds the signal power steady and allows the noise floor to move.

The Digital Status Output command controls the source, polarity, and override states. Quasonix has a technology called HyperTrack, which is a digital interface between the receiver and an antenna controller. This is intended to replace the standard analog AM/AGC that has been in use for decades. While digital, HyperTrack uses the same cabling and connectors to reduce rewiring costs.
