Model 3430-IF
I-Band Beacon Tracking Receivers
Version 4

 Beacon Tracking Receivers
A tracking receiver for antenna step tracking and automatic uplink power control

The Model 3430-IF Version 4 is the latest release of our reliable series of 3430 Beacon Receivers. The Model 3430-IF features an input of 50 - 200 MHz, Digital Level reference setting, Ethernet connectivity with M&C control interface, and power up temperature compensation for rapid signal acquisition. 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.

  1. 50 to 200 MHz standard input for 70 MHz and 140 MHz IF band applications
  2. Digital level reference setting, -10 to -70 dBm on 0.5 dB steps
  3. Ethernet connectivity with M&C control interface
  4. M&C control interface allows for remote monitoring from one or multiple locations
  5. RS-232/422/485  and Ethernet  All Standard
  6. Temperature stabilization compensation.

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.
