CSTReam commands direct the appropriate Sense output to the measurement
channels. The choices are constrained to appropriate selections by the applications.
The sense choices are fed to the FFT Analyzer calculate blocks by a
CSTReam:FEED command using the following syntax.
Example: CSTReam1:FEED SENSe1
CSTReam2:FEED SENSe3
CSTReam1:FEED SENSe5
CSTReam2:FEED SENSe6
or cstr1:feed sens1
etc.
In the first example, cstream1 is fed by the output of sense1, the Analog A
high resolution A/D converter, and cstream2 is fed by sense3, also the high
resolution A/D converter. In example two, the cstreams are fed by the digital
audio channel A and channel B signals.
A number of independent subsystems comprise the CALCulate subsystem. Each of
the subsystems is a sub-block of the CALCulate block. Data flows through the
sub-blocks in serial fashion. The CALCulate block has more than one instance of
some of the sub-blocks. The same named sub-blocks are differentiated by a numeric
suffix. The syntax of the CALCulate subsystem commands are application
dependent. One example of the signal flow in show in Figure 1–11. It illustrates the
FFT CALCulate subsystem.
