High Speed Timed Acquisition Parameter Descriptions
Acquisition tab
Signals tab Selects signals from which this process acquires data. Use the left and right
arrows to move desired signals from the Available list to the Included list.
Sensors signals for this process are only available from the following
conditioners: Models 493.21B and 493.25 conditioners and Models 494.25,
494.26, and 494.16 conditioners whose HWI settings are configured for high-
speed data.
Note The order of the signals in the Included list determines the order of the
columns of data in your data file. Use the up and down arrows to arrange
signals in the desired order.
List Filter With the List Filter, you can pare the list of Available signals according to text
you type in the entry box. Type text that describes the signal(s) you wish to
display.
For example, typing force displays all signals that include “force” in their labels.
You can also type a part of a signal description to display a signal type. For
example, to display displacement signals, you can type disp rather than
“displacement”.

Sample Rate
Specifies the time interval between which the process acquires data.
Specifies the rate at which the process acquires data. The maximum sample rate
depends on the system rate, the number of signals that you are sampling, and the
type of hardware used to condition the signal.
For a table with the maximum sample rates for various hardware, number of signals,
and system rates, see the About High Speed Timed Acquisition Process section.
Note MPT will change the number you enter to reflect the resolution of your
controller’s system clock rate. For instance, if you type in “12000” (Hz) and
press the Enter key, MPT will change the number to “12228” (Hz).
Total Samples Specifies the number of samples the process will acquire before it completes.
Sampling Duration Specifies the length of time the process will attempt to acquire data.
Continuous Sampling Causes the process to acquire samples continuously until it is interrupted.
