About Setting Up a Test to Acquire Trend Data
To acquire trend data during your test, you should define a Group process that
includes the Trend process and your command process.
Note Your command process is typically a Profile or Time History Output
process.
Typical trend tests are sequenced so that:
• When the command process starts, the Trend process starts.
• When the command process ends, the Trend process is terminated.
• When the Trend process ends, the Group process ends.
One pass of this Group process will yield only one point of data for each
statistical value, which is not enough to create a trend plot. To acquire more
points, you must set the number of times the Group process runs equal to the
number of command process passes you desire (this is typically greater than one
hundred).
