Programming flow diagrams are flowcharts that depict the most effective
order for programming Spectral Measurements Toolkit VIs. Use the
programming flow diagram in the SMT Programming Flow VI as a visual
guide for the order in which you should call VIs. This VI is located in
the
< LabVIEW >\examples\Spectral Measurements Toolset\
folder. The example is not intended to be executable,
Simulation
but rather to supply an informative block diagram depicting general
programming for applications using acquired or simulated data. Figure 1
shows the LabVIEW programming flow diagram for these applications.

The following steps describe the general programming flow of the Spectral
Measurements Toolkit.
1. Enter the time-domain data into the SMT Basic Zoom Power
Spectrum VI. This VI specifies the zoom settings in terms of only
center frequency and span. The VI performs zoom FFT processing and
returns a power spectrum in units V
