CoCo Operation for Transient Capture
Select a CSA Project
This section discusses the CoCo settings that are specifically related to transient
capture applications. For a complete explanation of these settings refer to the
Basic CoCo Operation section. To run a Transient Capture CSA press the Analysis
button and select a CSA Application Group that includes transient capture option.
These include: Transient Capture, Linear and Power Spectrum, and Frequency
Response. Then, choose an Analysis Function from the CSA files on the CoCo to
run.
Analysis Parameters: Window Type
First you must specify the Analysis Parameters under the Param. Button. Select
the averaging mode, averaging number and data window type. Transient Capture
commonly uses the Force, Exponential or combination Force-Exponential data
window function. Press the Apply button to accept the settings.
Figure 120. Select the data window type for transient capture.
Acquisition Mode
Next select Acquisition Mode under the Param. Acquisition Mode controls how
the data is acquired and under what conditions. It includes setting the trigger
mode, trigger source, level, conditions and overlap.
Select Trigger Mode using the Mode Button. Transient capture projects such as
impact hammer tests typically use Manual-Arm Trigger or Auto-Arm Trigger.
Auto-Arm automatically accepts the data frame into the average and prepares the
trigger for the next signal. Manual-Arm provides a graphical display of the data
and allows you to accept or reject the frame into the average.
