Module testing cable
The module testing cable allows bench testing and troubleshooting of RF power modules using a
direct connection to the transmitter.
The test cable provides a temporary connection from the transmitter to a power module that has
been removed from the transmitter and placed on a workbench. The test cable provides low-level,
safe voltages that allow the diagnosis of RF power module problems. (This is a unique feature of
Nautel transmitters.)
Plug-in power amplifier unit
The XR series power amplifier is a broadband, 1,000 watt plug-in unit compatible with all XR series
transmitters.
