Making Basic Measurements
Identifying Distortion Products
The analyzer automatically sets the attenuation so that a signal at
the reference level will be a maximum of −30 dBm at the input
mixer.
10.Press BW/Avg, Res BW, and then use the step-down key (↓) to reduce
the resolution bandwidth until the distortion products are visible.
11. To measure a distortion product, press Peak Search to place a marker
on a source signal.
12.Set the marked signal to the reference level by pressing Mkr → and
then
Mkr → Ref Lvl.
13.To activate the second marker, press Marker, Delta, Peak Search.
Using the
Next Peak key to place the second marker on the peak of
the distortion product that is beside the test signal. The difference
between the markers is displayed in the active function area. See
Figure 1-39.

14.To measure the other distortion product, press Marker, Normal,
Peak Search, Next Peak. This places a marker on the next highest
peak, the other source signal.
15.To measure the difference between this test signal and the second
distortion product, press Delta, Peak Search. Using the Next Peak key
to place the second marker on the peak of the second distortion
product. See Figure 1-40.
