Introduction
The FRA application is divided into two main
operation modes: Setting and Analysis mode.
When in Setting mode (the menu icon
appeared), the user can setup the FRA analysis
and then start it right after the FRA Run button is
pressed.
Time domain
When the FRA application is in Setting mode, the
top portion of the display window shows time-
domain waveforms of the input and the output
channel. This window disappears when in
Analysis mode.
Main display
In either mode, the FRA main display shows a
Bode plot with corresponding abscissa and
ordinates scales.
Connections
Background
The FRA application uses two analog channels of
the DSO as well as the GEN1 output of the
Arbitrary Wave Generator (AWG).
Connection
1. Connect the AWG output GEN1 to the input of
the Device-Under-Test (DUT).
2. Connect one DSO analog channel to the input
of the DUT.
3. Connect the output of the DUT to another DSO
analog channel.
