After installation, the NI-DSP Analysis VIs reside in the following VI library files (LabVIEW 

.LLB

 files) within

the DSP2200 option:

•

Signal Generation contains VIs that generate digital patterns.

•

Frequency Domain contains VIs that perform frequency domain transformations, frequency domain analysis,
and other transforms such as the Hartley transform.

•

Time Domain contains VIs that perform direct time series analysis of signals.

•

Filters contains VIs that perform IIR and FIR filtering functions.

•

Windows contains VIs that perform smoothing windowing.

•

Array contains VIs that perform arithmetic operations on arrays.

•

Memory Management contains VIs to perform allocating, indexing, copying, and freeing memory on the
AT-DSP2200 board.

•

Utility contains VIs for controlling the operation of the AT-DSP2200 board.

After installation, the eight analysis VI libraries appear in the Functions menu in the order shown in the preceding
list under the DSP2200 option.  You can reorganize the folders and the VIs to suit your needs and applications.

To access the analysis VIs from the block diagram window, choose DSP2200 from the Functions menu as shown in
Figure 1-1, proceed through the hierarchical menus, and select the VI you want.  The icon corresponding to that VI
appears in the block diagram and is ready to be wired.
