Frequency Response Analysis (FRA) is a licensed feature you can get by
purchasing the DSOXT3FRA upgrade.
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 (DUT). At each frequency, gain (A)
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.
To make connections
The waveform generator output is connected to a device under test (DUT). The
input to the device and the output from the device are probed by the
oscilloscope's input channels.
