Making Distortion Measurements
3 Change the center frequency to the value of the
second (400 MHz) harmonic:
•
•
4 Change the span to 50 MHz and re-center the signal:
•
•
5 Set the attenuation to 0 dB:
•
•
6 To determine whether the harmonic distortion
products are generated by the analyzer, first save the
trace data in trace 2 as follows:
•
•
7 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:
•
•
•
The
measured data in trace 1. The Marker Delta indicator
reads the difference in amplitude between the reference
and active trace markers.
