the r&s®fs-z10 coherence unit comes with a control software running on a pc. it controls the complete test setup, and calculates and displays the test results.it captures the i/q data of the sampled rf signals from the analyzers and calculates the signal differences based on the i/q data. this enables the compensation of the signal differences and saves the compensated or non-compensatedi/q data for further analysis.
the settings specified in the graphical user interface of the control software are used to configure the analyzers automatically. there are three different modes of operation:
- calibration mode: automatic compensation of signal differences (phase, timing and/or amplitude) in the test setup including cables for connecting the device under test
- measurement mode: measurement of signal differences (phase, timing and/or amplitude) between the signals of device under test
- compensation mode: compensation of signal differences (phase, timing and/or amplitude) of the device under test
the r&s®fs-z10 coherence unit supports the r&s®fsq or r&s®fsg signal analyzers from rohde & schwarz. this concept reduces investment costs because it allows existing equipment to be reused without modification and provides accurate measurement results:
- high performance signal analyzers with excellent rf performance
- signal analysis bandwidth up to 120 mhz with low evm
