The FRA tab
The FRA tab lists the optional FRA-related measurement that you can add to the Results bar.
Note: The FRA tab opens if the 2-SOURCE or the 2-UL
TIMATE license options is installed.
To open the FRA measurement tab:
1. T
ap the Measure button.
2. Tap the FRA tab.
To add a measurement to the Results bar:
1. Select the signal sources. If the measurement requires two signal sources, select the sources in the Source 1 and Source 2 fields.
2. Select the Control Loop Response (Bode) measurement.
3. Tap Add. You can also double-tap a measurement to add it to the Results bar.
Frequency Response Analysis (FRA) Measurement panel
Measurement Description
Control Loop Response (Bode) Plots the gain as 20 log (V
out
/V
in
) and phase dif
ference between V
in
and V
out
at each frequency within
the swept band. The resulting plot is commonly referred to as a Bode Plot.
Control Loop Response (Bode) measurement configuration panel
Double-tap a Power measurement badge to open the Control Loop Response
(Bode) measurement configuration menu. Use this menu to
set the measurements source, add a custom name (label) for the measurement and other parameters.
Field or control Description
Input Source Selects the channel connected to the input side of the DUT. Tap the field to show the list of available
input sources.
Output Source Selects the channel connected to the output side of the DUT. Tap the field to show the list of available
output sources.
Label Sets the name of the measurement. You can use the default name, or double-tap in the field and
change the label using a connected keyboard or the virtual keyboard.
Generator Sets the signal source to Internal or External and generates stimulas as a series of sine waves with
configured amplitude. The sine waves are sent to the input of the DUT
.
The AFG31000 Series and AFG3000 Series are the supported external signal source.
