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.
The description of FRA Menu is shown as the follows:
