Integrating the Spectral Measurements Toolkit
You can use the Spectral Measurements Toolkit for the following
applications:
• Frequency-domain measurements such as:
– Adjacent channel power ratio (ACPR)
– Channel spectrum
– Power-in-band measurements
– Average and peak power
– Power spectral density
– Spectrum limit and mask testing
• Modulation-domain measurements such as:
– Frequency deviation
– AM modulation index
• Component-level measurements such as characterization of
oscillators, mixers, and filters
Locating the Spectral Measurements Toolkit
The Spectral Measurements Toolkit contains LabVIEW VIs and
LabWindows/CVI functions. In LabVIEW, Spectral Measurements
Toolkit VIs are located on the Functions»RF Communications»
Spectral Measurements and Functions»Addons»Modulation palettes.
SMT functions are located on the LabWindows/CVI function panel
under Library»Spectral Measurements Toolset and Library»
Analog Modulation.
Note Some Spectral Measurements Toolkit VIs and functions configure hardware,
meaning their operation requires installing specific hardware instrument drivers. For
more information about supported hardware, refer to the NI Spectral Measurements
Toolkit Readme, located at Start»All Programs»National Instruments»
Spectral Measurements.
For simplicity, this document pertains only to using VIs in the LabVIEW
development environment, except in the Using LabWindows/CVI Spectral
Measurements Examples section. In most cases, the same guidelines apply
to using functions in the C programming environment.
Note Documentation for LabWindows/CVI functions can be found in the NI Spectral
Measurements Function Reference Help, located at Start»All Programs»National
Instruments»Spectral Measurements»CVI Support.
