National Instruments Spectral Measurements and Modulation Toolkits

The National Instruments Spectral Measurements and Modulation Toolkits provide a set of flexible spectral measurements and extend the built-in analysis capability of NI LabVIEW and LabWindows/CVI software.

The Spectral Measurements Toolkit provides a set of flexible spectral measurements including power spectrum, peak power and frequency, in-band power, adjacent-channel power and occupied bandwidth, as well as 3D spectrogram capabilities.

It contains virtual instruments (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 optimised algorithms and the GHz processing of a PC delivers good measurement throughput.

Like the Spectral Measurements toolkit, the Modulation Toolkit extends the built-in analysis capability of NI LabVIEW and LabWindows/CVI software. This toolkit can be used to rapidly develop custom applications for research, design, characterisation, validation, and test of communications systems and components that modulate or demodulate signals.

The numerous Modulation Toolkit applications includes implementation of analog and digital modulation schemes such as AM, FM, PM, ASK, FSK, MSK, GMSK, PSK, QPSK, PAM and QAM which forms the foundation for many communication standards including in 802.11a/b/g/n, ZigBee (802.15.4), WiMAX (802.16), and communication systems including RFID, satellite communications and commercial broadcasts.
