About Data Acquisition Resulting From Command Stop Behavior
When a test is stopped by an operator, MPT continues to acquire data through all
subsequent transition periods.
Example Suppose you are running a procedure with a cyclic waveform, and wish to
acquire data on all the command cycles. The procedure requires 100 command
cycles and 100 data acquisition cycles, where 1 cycle=1 second.
You push the Stop button during the test, and it takes 3 seconds to taper to zero.
Those 3 cycles count as command and data acquisition cycles.
Then you push the Start button. It takes 5 seconds for the system to taper back up
to full amplitude. Those 5 cycles also count as command and data acquisition
cycles.
When the test reaches its “natural” done state (after 100 cycles,) it performs 100
command cycles and 100 data acquisition cycles, 8 of which are tapered.
Note It is important to realize that, because of the 8 tapered cycles, some data
points (those that are smaller than the specified sensitivity) might be
missed if you are taking peak/valley data.
