Description
A tracking receiver for antenna step tracking and automatic uplink power control! The Models 3430-L, LD, LF, and LW are fully frequency agile satellite receivers designed to provide a linear DC reference voltage proportional to the received signal level of a satellite beacon or narrow-band SCPC carrier. Frequency selection on 10 kHz steps may be accomplished from the front panel or remote control. Pre-detection noise bandwidth of 50 kHz facilitates accurate tracking at very low C/N levels
