11.17.14 Averaging I/Q Data
The R&S ESR has averaging capability also for I/Q measurements, i.e. I/Q data can be
averaged over several test runs. This is subject to the following conditions:
●
An external trigger signal must be available for data measurement, and the trigger
signal must be phase-locked to the signal measured.
●
The same reference-frequency signal must be used for the DUT and the
R&S ESR.
●
Internal I/Q data averaging is supported up to 512 k I/Q samples.
If all of the above conditions are fulfilled, no phase shift will occur between consecutive
test runs. Phase shift may falsify the measured average so that in extreme cases a
value of 0 is obtained.
The default setting of the instrument for data measurement without averaging has to be
changed as follows:
