The National Instruments Spectral Measurements Toolkit
provides a set of flexible spectral measurements in LabVIEW and LabWindows/CVI,
including power spectrum, peak power and frequency, in-band power,
adjacent-channel power, and occupied bandwidth, as well as 3D spectrogram
capabilities. In addition, the Spectral Measurements Toolkit contains VIs and
functions for performing modulation-domain operations such as passband (IF) to
baseband (I-Q) conversion, I-Q to IF conversion, and generation/analysis of
analog modulated signals. The combination of these optimized algorithms and the
GHz processing of your PC delivers unmatched measurement throughput.

The
Spectral Measurements Toolkit can be used with a variety of NI hardware
including the PXI-5660 RF vector signal analyzer, digitizers, and other modular
hardware, as well as third-party stand-alone instruments.
