IF Modulator Parameters
11.3.3
L-Band Monitor Frequency
The L-Band monitor monitors the modulation outputs.
The L-Band Monitor Frequency parameter displays a read-only value of the L-Band monitor
frequency value. The interface’s parameter values are 1080 MHz at
−
45 dBm.

11.3.4
Output Impedance
The Output Impedance parameter allows controlling the IF modulator output impedance of the
encoder to coordinate with the impedance of the next stage UCM (up-converter modulator).
The available options are: 50 and 75 Ohm. The Output Impedance default value is
50 Ohm
