:FRANalysis Commands
Introduction to
:FRANalysis
Commands
The FRANalysis subsystem controls the Frequency Response Analysis feature in
the oscilloscope.
The Frequency Response Analysis (FRA) feature controls the built-in waveform
generator to sweep a sine wave across a range of frequencies while measuring the
input to and output from a device under test (DUT). At each frequency, gain (A)
and phase are measured and plotted on a frequency response chart.
Reporting the Setup
Use :FRANalysis? to query setup information for the FRANalysis subsystem.
Return Format
The following is a sample response from the :FRANalysis? query. In this case, the
query was issued following a *RST command.
