N9320A Spectrum Analyzer 51

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 Factory)

Press > Center Freq > 300.5 > MHz

Press > Span > 5 > MHz

4 Reduce the RBW until the distortion products are visible:

Press and

5 Move the signal to the reference level:

Press

> Mkr -> Ref Lvl

6 Reduce the RBW until the distortion products are visible:

Press and

7 Activate the second marker and place it on the peak of the

distortion product (beside the test signal) using the Next Pea:

Press

> Delta > Delta (On)

Press > Next Peak

8 Measure the other distortion product:

Press

> Normal

Press > Next Peak

NOTE

The coupler should have a high degree of isolation between the two

input ports so the sources do not intermodulate.
