2 Set one source (signal generator) to 300 MHz and the other source
to 301 MHz, for a frequency separation of 1 MHz. Set the sources
equal in amplitude as measured by the analyzer (in this example,
they are set to –5 dBm).
3 Set the analyzer center frequency and span:
Press Preset (With Preset Type of DFT)
Press Frequency > 300.5 > MHz
Press Span > 5 > MHz
4 Reduce the RBW until the distortion products are visible:
Press BW and
FM
5 Move the signal to the reference level:
Press Peak Search
Press Marker > Marker To > To Reference
6 Reduce the RBW until the distortion products are visible:
Press BW and
FM
7 Activate the second marker and place it on the peak of the
distortion product (beside the test signal) using the Next Peak:
Press Marker > Mode > Delta
Press Peak Search > Next Peak
8 Measure the other distortion product:
Press Marker > Mode > Normal
Press Peak Search > Next Peak
