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
