Block Size: the block size of the time block signals.
Average Mode: Exponential, Linear or Peak Hold applied to frequency domain,
power spectra averaging. Time Linear and Time Exponential applies to time
domain averaging.
Average Number: the Average number of linear averages. When exponential
average is selected as the average mode, 1/(Average Number) is used as the
exponential factor.
Window Type: type of data window.
The selection candidates of these fields are defined in the CSA Editor. That is, the
maximum sampling rate, maximum number of input channels, etc are defined
when you create the CSA. For example if you select a Maximum Sampling Rate of
1 kHz in the CSA Editor then higher sampling rates will not be available on the
CoCo device. If a higher sampling rate is required then you must modify the CSA
and download it to the CoCo. Although this behavior may seem limiting, it should
be noted that it allows the user to choose exactly the analysis functions and
optimize the performance of the CoCo device to suit your specific needs and is one
of the unique features of the CoCo system.
Weighting Type: CoCo offers Z, A, B, and C weighting.
