RX1 Modulated Input

Nov 2023

Introduction

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.

Hardware Connections

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.

AVP Output Parameters

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
