seconds). This maintains a high resolution with respect to typical data acquisition rates. However, because
Rollover Time and Running Rollover Time reset to zero every hour, they lose reference to where they
occur within the test.
It is possible to obtain a composite time reference that has the desirable characteristics of both Time and
RolloverTime. To do this, select both types of signals for the data acquisition process (Time and
RolloverTime), map the signals to variables, and create a calculated variable derived from the Time and
RolloverTime variables, as follows:
CompositeTime = floor(Time/3600) x 3600 + RolloverTime
Where “CompositeTime” is a calculated variable and the “floor” function is the largest integer less than or
equal to the specified number.

High-Speed DAQ Activity Overview

Note:
This activity is only available in the Multipurpose Elite application.
Note:
This activity cannot be used with 793 demo or simulation software.
The High-Speed DAQ activity records short bursts of conditioned sensor data. This activity is typically
used in tests where it is triggered and then quickly interrupted by other activities, so that it is only active
for short periods of time.
Note:
Unlike other Data Acquisition activities, this activity is not designed to acquire data for the duration
of a test, or for even long periods of time within a test.
Configuration of this activity requires the following information:
• Type of controller hardware you are using - 494 hardware-based system (FlexTest 40, 60, 10, 200) or
493 hardware-based system (FlexTest GT, TestStar IIm)
• Version number of the 793 controller (Station Manager) software
• Version number of the MPE software
