Model S W R23-LL-Band Beacon Tracking Receiver
An affordable tracking receiver for antenna step tracking and automatic uplink power control
The Model SWR23-L Version 1 is the latest release of our reliable series of Beacon Receivers. With Version 1 firmware we now offer the full L-band range of 930 to 2300 MHz, Digital Level reference setting, & M&C. Frequency selection on 10 kHz steps may be accomplished from the front panel or via remote control. Pre-detection noise bandwidth of 50 kHz (or factory option of 25 kHz)
facilitates accurate tracking at very low C/N levels.
� Wide bandwidth, 930 to 2300 MHz standard
� Digital level reference setting, -40 to -100 dBm on 0.5 dB steps
� RS-232/422/485 and Standard
The output of the Beacon Receiver is a DC voltage proportional to the input signal level to facilitate both antenna tracking control and automatic power control. A Loss of Carrier indicator is provided in the event the tracking signal is lost. Form "C" relay contacts provide an external Loss of Carrier Alarm. A front panel VFD displays operating frequency, relative signal level, carrier lock or alarm, and input Level.
