For receiver measurements, external signals that are fed in via the analog or digital audio inputs, as well as internally generated signals and audio files, can be modu- lated onto an RF carrier. For transmitter measurements, the transmitter signals are demodulated and analyzed. The spectrum analyzer is used to display demodulated audio signals. Depending on the type of modulation, either the modulation deviation or modulation...

Built-in interferer The R&S®CMA180 can generate two RF signals. If these signals are positioned outside of the DUT's receive win- dow in such a way that at least one intermodulation prod- uct lies within the receive window, it is possible to assess the receiver quality. The built-in interferer allows users to measure co-channel rejection and adjacent channel sup- pression, eliminating the need to employ an additional generator to generate the interfering signal. It is easy to perform intermodulation measurements with the R&S®CMA180 since the user can generate the two RF signals at different levels...

Built-in sweeping spectrum analyzer with time domain analysis (zero span) The R&S®CMA180 features a built-in sweeping spectrum analyzer. Extensive configuration options make this a ­ nalyzer a universal tool for testing all types of DUTs. The spectrum analyzer has two operating modes: full span and user-defined spans. The zero span mode enables a ­ nalysis in the time domain. In combination with the triggers, it is possible, for instance, to display transients. Pulsed signals can also be analyzed in the spectrum analyzer's time domain. Depending on the sweep time setting, the video trigger allows...

Advanced touchscreen plus rotary knob Users can operate the R&S®CMA180 completely via the touchscreen. All functions can be quickly accessed. Mea- surement results are clearly and conveniently displayed. Users can also use the rotary knob to change settings, an especially useful feature that allows them to "scroll through" the frequencies and levels and immediately see the impact on the measurement results. Predefined test scenarios for minimal configuration effort, or expert mode for maximum freedom Predefined scenarios for standard measurement tasks en- able users to configure the R&S®CMA180...

Different possibilities for displaying parameters Users have a choice of two modes for displaying param- eters and measurement results. The tab mode is best for displaying the values in detail. All generator and analyzer values are displayed in separate full-screen tabs. The split screen mode offers a complete overview, where the generator and analyzer values are displayed simultane- ously. Generator settings are changed on the left side of the screen and the results are instantly displayed on the right side. The operating controls for the spectrum ana- lyzer can be hidden, and the results displayed...

Automation with Ready-to-use solution for configuring application test sequences R&S®CMArun is available for test sequence control. R&S®CMArun provides a graphical user interface for programming a test sequence. Individual settings and measurement tasks can be configured and arranged in a specific sequence. Sequences, loops and conditional queries help users easily create and execute complex test sequences. Each setting and measurement value is logged and then summarized and stored in a report. For measure- ments with limit values, pass or fail indicators can be dis- played for each measurement....

receiver tests For RF transmitter tests, all relevant parameters are mea- sured, including transmit power, transmit frequency, fre- quency error and modulation parameters. The transmit power can be as high as 150 W. A spectrum analyzer is available for examining the signals in the frequency do- main. Harmonics and the adjacent channel power can also To investigate the receiver's sensitivity, RF signals are gen- erated at very low powers. The signal power can be re- duced to as low as -140 dBm. To analyze the audio signal, the audio signal demodulated by the DUT can be played Many different connectivity...
