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.
5.Use the Arbitrary Function Generator (Optional)
Check to enable FRA function and show FRA scale
line and chart.
When unchecked, FRA information is shown on the
FRA window.
When checked, FRA information is shown on the
waveform display area.
Turn Multipurpose knob to move the marker, view
measured gain and phase values.
When unchecked, the sweep step is 0.1dB.
When checked, the sweep step is 0.01dB.
Input V is input from CH1.
CH1
Output V is input from CH2.
(Note: The menus are not for selecting menu items, only
CH2 for showing information.)
Turn Multipurpose knob to set frequency sweep min
value. Check to enable fine-tuning.
Turn Multipurpose knob to set frequency sweep max
value. Check to enable fine-tuning.
Turn Multipurpose knob to set waveform generator
amplitude. Check to enable fine-tuning.
Note: The amplitude range is 2 mVpp to 6 Vpp.
Adjust scale of gain plot, range from 5dB to 500dB.
Adjust offset of gain plot, range from -250dB to
250dB.
Adjust scale of phase plot, range from 5° to 180°.
Adjust offset of phase plot, range from -180° to 180°.
Autoscale gain and phase plots.
