Dual Antenna Arbitrator (MXP) Setup

•
Power meter
Record TX Output @ 1dB compression point. ____ dB
10. Measure RX signal level at the RX Input to the satellite modem using a spectrum analyzer, modem signal
level, EbNo or SNR value. Record RX Input ____ dB
11. Compare measured RX output levels and notify operators if the difference is greater than +/-1.0 dB of
each other … this is for informational purposes only, so that the operators know differences in
performance when switching. RX in-line attenuators may be installed at the LNB input to the Dual
Antenna Arbitrator which has the higher RX signal level, if balanced performance is desired, but it is not
necessary.
12. Compare measured TX results to determine if the outputs are balanced. Outputs must not be greater
than +/-2.0 dB MAX of each other. If necessary, add TX attenuation via BUC M&C, or by installing in-line
attenuators (not supplied) at the input, of the BUC which has the higher power output to balance the
performance of the two antennas /- 1.0 dB.
13. Verify with the NOC that the TX outputs (RX signal level at the network) from ANT A & ANT B are equal
+/- 1.0dB.
14. Select Auto Mode.
