FRA
FRA
Check to enable FRA function and show FRA scale
line and chart.
Transparent
When unchecked, FRA information is shown on the
FRA window.
When checked, FRA information is shown on the
waveform display area.
Marker
Turn Multipurpose knob to move the marker, view
measured gain and phase values.
Sweep Step
Fine
When unchecked, the sweep step is 0.1dB.
When checked, the sweep step is 0.01dB.
Setup

Gain Offset
Adjust offset of gain plot, range from -250dB to
250dB.
Phase Scale
Adjust scale of phase plot, range from 5° to 180°.

Analysis
Run/stop the analysis.
F: Frequency; G: Gain; P: Phase.
To run the frequency response analysis, do the following:
1. The waveform generator output is connected to a device under test. The input to the
device is probed by CH1of the oscilloscope. The output from the device is probed by
CH2of the oscilloscope.
2. Push the Utility button, select Function in the bottom menu, select FRA in the left
menu
3. In the bottom menu, select
FRA. In the right menu, check
FRA, and set other
menu items.
4. In the bottom menu, select Setup or Chart. In the right menu, set the menu items.
5. In the bottom menu, check
Analysis to run the analysis.
