While you cannot currently display frequency domain data in the
NI-SCOPE Soft Front Panel, you can get some useful scalar
information. Try CTRL-M, which will bring up the Measurements
Window. You can add measurements like Frequency, Average
Frequency, and FFT Frequency (these will be a single, scalar value
rather than a spectrum).
NI Signal Express provides simple ways to see frequency domain data in an interactive environment.
If you are a LabVIEW user, you can use the NI-Scope Express Block and
the Spectral Measurements Express Block to configure the digitizer and
display frequency domain data in two interactive steps.
If you are a C/C++, CVI, LabVIEW, or Visual Basic user, the NI-SCOPE
driver provides programmatic access to frequency domain data (and much
more) through the built-in Measurement Library. Using Fetch Array
Measurements, you can get an array of data representing the FFT
Amplitude or Phase spectrum. See the following examples for a
demonstration:
niScope EX Advanced Measurement Library.vi (LabVIEW)
AdvancedMeasurementLibrary.prj (LabWindows/CVI)
MeasurementLibrary.c (C)
AdvancedMeasurementLibrary.frm (Visual Basic)
