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
(Note: The menus are not for selecting menu items,
CH2
only 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° .
