48 N9320A Spectrum Analyzer

3 Functions and Measurements

The signal produces harmonic distortion products (spaced

200 MHz from the original 200 MHz signal) in the analyzer

input mixer as shown in Figure 16.

4 Change the center frequency to the value of the first

harmonic:

Press > Next Peak

Press

> Mkr -> CF

5 Change the span to 50 MHz and re- center the signal:

Press > 50 > MHz

Press

> Mkr -> CF

6 Set the attenuation to 0 dB:

Press > Attenuation > 0 > dB

7 To determine whether the analyzer generates harmonic

distortion products, first display the trace data in trace 2 as

follows:

Press > Select Trace > Trace 2

Press Clear Write

8 Allow trace 2 to update (minimum two sweeps), then store

the data from trace 2 and place a delta marker on the

harmonic of trace 2:

Press > View

Press

> Delta > Delta (On)

The analyzer display shows the stored data in trace 2 and

the measured data in trace 1. The MarkerΔ indicator reads

the difference in amplitude between the reference and active

markers.

9 Increase the RF attenuation to 10 dB:

Press > Attenuation > 10 > dB
