It has been quite some number of years since I dealt with Modulators and Receivers, so I did struggle a little with this recently, these are some notes of the values I used, just to get a Mod/Demod setup going.

See below for the connection method between the AVP and the RX1.


The Monitor F-Type output of the AVP is connected directly to the RF input of the RX1 (RX4 is on the left). There is no up-convertor or attenuator in use.

Below is the output settings I used on the AVP Modulator.

=== Output Parameters ===
RF Carrier ID State            On (don't confuse this with Modulation on)\\ 
Output Select                  L-Band\\ 
Output State                   On Reduced Power (we don't want to overload the RX1 input)\\ 
Output Power-up State          (Last State)\\ 
\\

=== L-Band Output ===
Frequency Input Mode           L-Band Frequency\\ 
L-Band Frequency               1070 MHz\\ 
Reduced L-Band Line-up Power   -5\\ 
Nominal L-Band Power           -10\\ 
L-Band Spectrum Sense          Inverted\\ 
L-Band Tilt                    0\\ 
L-Band Up-converter Frequency  2500 MHz\\ 
Upconverter Power              Off\\ 
Upconverter Reference          Off\\
