Set Up Spectrum Trace
This procedure explains how to use the Spectrum Analyzer software option to display a
spectrum trace, an FFT of your input trace.
1. Choose Analysis > Spectrum Analyzer; the Spectrum Analyzer dialog appears. Be sure
Enabled is checked so the spectrum trace is displayed.
2. To use 1 Input or a differential probe connected to a single channel (the default), touch
Input1 and choose any channel, zoom, math, or memory source.
OR
To input the difference between two sources, select Input 1-Input 2, then touch Input1
and choose the first source. Repeat for Input2.
Example: You can input the difference between two probes connected to two different
channels. This option eliminates the need to first set up a math trace to calculate the
difference.
