9522B L-Band Transceiver Product Information Guide
7.0 Installation of the 9522B in place of a 9522A
The 9522B is designed to replace the 9522A with the assistance of an optional adapter plate and cables.
An adapter plate is mounted onto the 9522B and provides mounting points similar to those of the 9522A.
The antenna cable adapter provides a cable-mounted TNC connector similar to the 9522A. The Multi-
interface adapter cable provides a mechanical and electrical interface similar to the 9522A (although please
see the note in section 7.2 below)
7.1 Physical characteristics
