R&S FSH Interference Analyzer (R&S FSH-K15/ -K16)
Measuring the Spectrum
Operating Manual 1173.6275.12 - 30 156
5.1.3 Analyzing Interference Measurements
5.1.3.1 Trace Mathematics ("Diff Mode")
The Interference Analyzer provides a quick way to apply trace mathematics ("Trace -
Memory Trace") and thus a quick way to compare the current results with a previous
one.
► Press the MEAS key.
► Press the "Diff Mode" softkey.
When you turn on the "Diff Mode", the R&S FSH saves the current trace ("memory
trace") and will subtract this trace from the live traces resulting from future sweeps.
For more information on general trace mathematics supported by the R&S FSH see
"Using Trace Mathematics" on page 115.
Note that "Diff Mode" is only available in the Spectrum Overview result display of the
Interference Analyzer.
