Introduction to the Spectral Measurements Toolkit
NI provides add-on software toolkits, such as the Spectral Measurements Toolkit (included) and the
Modulation Toolkit, that extend the capability of the RF vector signal analyzer to include frequency- and
modulation-domain measurements, and analysis of analog-modulated IF signals.
Note You must install the Spectral Measurements Toolkit CD packaged with your RF vector signal
analyzer. The Spectral Measurements Toolkit is necessary for analysis of modulated signals using the
RF vector signal analyzer.
Use the Spectral Measurements Toolkit (SMT) VIs and functions for frequency-domain analysis,
measurement, and display of data acquired using the RF vector signal analyzer. The SMT can perform
several operations, including the following:
• Zoom Fast Fourier Transform (FFT) processing and spectrum averaging
• Spectral measurements such as band power, adjacent channel power, and peak frequency and
magnitude
• Spectrogram display and analysis
• RF vector signal analyzer hardware configuration for frequency-domain measurements
For complete information about SMT VIs and functions, refer to the Spectral Measurements Toolkit
documentation, accessible from Start»All Programs»National Instruments»Spectral
Measurements. For more information about the Modulation Toolkit, refer to ni.com/rf/
software

SMT Example Applications for LabWindows/CVI and C
The Spectral Measurements Toolkit includes LabWindows/CVI and C examples for the RF vector signal
analyzer hardware. You can access the Spectral Measurements Toolkit examples at Start»
All Programs»National Instruments»Spectral Measurements»CVI Support. The example files
are in the location specified in the NI RF Signal Analyzers Readme.
Appendix A: Hardware Front Panel Connectors and Indicators
The following sections describe the connectors and LED indicators on the front panels of all three RF
vector signal analyzer hardware modules. All input and output terminals, except the PFI 1 connector on
the NI 5622 IF digitizer front panel, are AC-coupled.
Note Refer to Figure 3,
Interconnection of Devices with Included NI 5660 Cables, for illustrations
of standard RF vector signal analyzer hardware module front panel interconnections.
