2. Parameters used by the signal analyzer functions such as FFT, Auto
Power Spec, Coherence, FRF
3. Time Stream Data Recording Settings
4. Block Data Save Settings
5. Trace Settings
The CSA is designed to control how the data is processed, not how the data is
acquired. When the CSA is changed, the processing functions are changed
according to the new CSA, but the data acquisition parameters do not change.
For this reason, the following settings have global effect and are not part of CSA
project:
1. Sampling Rate
2. Input Channels: sensitivity, coupling, channel labels
3. Output Channel: output waveform settings
All pre-programmed CSA projects have predefined parameters that are loaded
when the project is selected. You can modify the parameters on the CoCo-80
from the Param Soft Button in the Display screen. Modified CSA projects can be
saved with a different name using the Save As soft Button in the Analysis screen
so that the original projects are not overwritten.
Most pre-programmed CSA projects carry a variable called Maximum Sampling
Rate. This is the sampling rate that this CSA can safely execute without exceeding
its computational resource limit. Maximum Sampling Rate is used to limit the
selection of the sampling rates.
Preprogrammed CSA projects
The CoCo-80 is preprogrammed with a set of default CSA projects which provide
a wide range of options that meet most users’ needs. Additional CSA projects may
be downloaded from the Crystal Instruments web site. In addition, by using CSA
Editor the advanced users may edit or develop their own customized CSA projects
to meet their specialized needs. Typical default CSA projects are given below.
