Accurate and flexible Top RF performance for transmitter and receiver tests For RF transmitter tests, all relevant parameters are m easured, including transmit power, transmit frequency, frequency 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 d omain. Harmonics and the adjacent channel power can also be measured. To investigate the receiver's sensitivity, RF signals are generated at very low powers. The signal power can be r educed to as low as –140 dBm. To analyze the audio signal, the...

Extensive measurement functionality Analog modulation and demodulation The R&S®CMA180 supports CW, AM, FM, PM and SSB modulation and demodulation methods. 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 modulated 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 depth is measured...

Audio quality tests All audio signals - both externally fed signals and demodulated audio signals - can be analyzed. Highpass, lowpass and weighting filters can be applied to the audio signals. The quality of the audio signal is determined with SINAD, SNR and THD. Users can select any frequency to be the test frequency. SINAD, SNR and THD are determined and displayed simultaneously. There is no need to switch between SNR and SINAD measurements. The spectrum analyzer is used to examine the signals in the frequency domain. FFT spectrum application The integrated FFT spectrum application is used...

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 nalysis a in the time domain. In combination with the triggers, it is possible, for instance, to display transients. Bursted signals can also be analyzed in the spectrum analyzer's time domain. Depending on the sweep time setting, the video trigger allows...

Convenient operation Advanced touchscreen plus rotary knob Users can operate the R&S®CMA180 completely via the touchscreen. All functions can be quickly accessed. Measurement 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 enable users to configure...

Digital receiver and transmitter measurements Digital receiver measurements The R&S®CMA180 can generate test signals for igital d r adio standards. Signal content can be configured to match test requirements. Signals can carry audio test tones or pseudo random bit sequences (PRBS), for e xample. Signaling parameters such as DMR color code can be configured on the instrument’s intuitive GUI, making it easy to perform receiver tests for digital s tandards such as DMR, NXDN and APCO P25. The digital signal generator can be used for testing digital communications systems; plus it supports POCSAG....

Alternative: Analysis of digital signals using R&S®VSE vector signal explorer software The R&S®CMA180 can analyze digital signals with its i ntegrated vector signal analyzer. Alternatively, the R&S®VSE vector signal explorer software can be used. R&S®VSE is a powerful software analysis tool that can be used to nalyze almost any digital signal. The R&S®VSE a software is perated in vector signal analyzer mode and o configured for the relevant signals. For online analysis, the R&S®CMA180 continually delivers data to the R&S®VSE software, which directly analyzes the data and displays the associated...
