1.1 Video.
The video input is buffered, combined with the audio subcarrier/s,
then DC level restored, limited by a white level clipping circuit, pre-
emphasized and FM modulates the transmitter RF carrier.
Avalon RF offers the following video indices of modulation:
•
Industry standard frequency deviation of 2MHz.
Compatible to GMS, L3 and others.
•
Wide frequency deviation of 4MHz.
1.2 Audio.
The audio input/s are buffered and FM modulated on subcarrier/s.
The factory preset subcarrier frequency is 6.5MHz but can be factory
programmed to any frequency from 5MHz to 7.5MHz. The
subcarrier/s is synthesized.
1.3 Talk Back Audio Channel (optional).
The talk back audio channel allows the camera operator (on the
transmit side) to receive instructions from the operator at the
receiver’s side. It drives an earpiece.
1.4 Two Way Wireless Digital Link (WDL) (optional).
The WDL serves as a Pan-Tilt-Zoom (PTZ) / general-purpose two-
way RS422/RS485 digital link.
1.5 RF Outputs.
The transmitters have two RF outputs (Only 1 for a standard unit,
without WDL or Talk Back Audio Option). A female SMA connector
for the main transmitter and a MCX for the WDL.
Both outputs feed antennas, either directly or through a cable.
