RF Module testing cable and test load
The RF 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 an RF 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.
The RF power module test load provides a low power load suitable for operating an RF power
module on the test cable only.
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.
