Distortion measuring filters, AF post demodulation filters and IF passband filters, are built in for inclusion in relevant measurement paths.
The signal obtained from the demodulators, when in Tx test mode, is fed to an AF amplifier and can be monitored on the built-in loudspeaker, on headphones connected to the accessory socket, or taken from the DEMOD OUT connector to other equipment. The monitor has a wide range of test capabilities including base station, mobile and transponder commissioning and servicing, radio telephone system and radio pager testing, as well as production testing to all of the above.
