PDF1. What is the Spectral Measurements Toolkit?
The Spectral Measurements Toolkit (SMT) is the best NI software package for frequency-domain measurements. The SMT offers several high-performance fast Fourier transforms (FFTs) to make frequency-domain measurements faster than ever before. The SMT provides high-level functions that configure the hardware and make measurements using spectral properties with which customers are already familiar. The SMT works with both NI LabVIEW and LabWindows/CVI.
The Modulation Toolkit extends LabVIEW and LabWindows/CVI analysis capabilities with functions and tools for signal generation, analysis, visualization, and processing of standard digital and analog modulation formats as well as custom formats. Though the Modulation Toolkit does not require hardware, you can use it with NI RF, arbitrary waveform generator, and digitizer products, as well as traditional instrumentation.
The Modulation Toolkit is part of the National Instruments platform engineers can use to build custom measurement solutions that include modulation-related measurements and analysis. This is radically different from alternatives such as traditional instruments, which implement specific measurements well but are not amenable to customization. The Modulation Toolkit also differs from software tools that are useful for pure simulation but fall short when you want to integrate custom hardware-specific tasks. With the Modulation Toolkit, you can inject impairments into a simulated or live system to determine system robustness; this capability is not available in most software packages.
The Modulation Toolkit supports standard analog and digital modulation formats as well as custom formats. The toolkit performs modulation and demodulation, and can generate impairments used to simulate non-ideal operating conditions. The Modulation Toolkit also includes common modulation-related measurement and visualization tools.
