Frequency Response Analysis

The Frequency Response Analysis (FRA) feature controls the built-in waveform generator
to sweep a sine wave across a range of frequencies while measuring the input to and
output from a device under test. At each frequency, gain and phase are measured and
plotted on a frequency response Bode chart. When the frequency response analysis
completes, you can move a marker across the chart to see the measured gain and phase
values at each frequency point. You can also adjust the chart's scale and offset settings for
the gain and phase plots.
Note: If the signal is disturbed seriously, it is recommended to select Average in Acquire
Mode before running the analysis, the averages can only be set as 4 or 16, and then run the
analysis.
Push the Utility button, select Function in the bottom menu, select FRA in the left menu.
