Radio test set generates output signal up to 20MHz

Rohde & Schwarz has lowered the cost of testing analogue radios in the 100kHz to 3GHz frequency range. It is using an integrated ARB generator for software implemented test signal generation in the R&S CMA180 radio test set. Users can generate any output signal with a bandwidth of up to 20 MHz – a feature normally offered only in radio communications testers several times more expensive.  

A large touchscreen and straightforward menu provide for especially simple and fast operation.

The tester allows users to generate additional signals with just a few mouse clicks, such as interfering signals for co channel rejection measurements. Service technicians and test engineers can also use the instrument's integrated sequencer to configure and run automatic test sequences.      

The test set is designed for 100W continuous input power and 150W peak input power and is the only tester in its price class capable of processing such high input levels. Thanks to digital signal processing, the test set delivers extremely precise measurement results and is ideal for testing software defined radios.      

For high precision power measurements, Rohde & Schwarz offers optional extremely linear power sensors that can also be used with the R&S CMA180.
