Operating the DC Power Analyzer 3

If a trigger source is grayed out, it is unavailable. For example,
current levels are not available as trigger sources on outputs that
have been grouped (paralleled). Note also that a trace must be turned
on for it to be used as a trigger source. This differs from the way that
current and voltage level trigger sources are selected in Scope View.
The Level field lets you specify a trigger level if you selected a
Voltage level or Current level as the trigger source. Along with the
level, you must also specify a Slope - if the measurement will be
triggered on the positive (up-slope) or negative (down-slope) portion
of the waveform.
The Trigger Position % of Duration lets you specify a trigger offset.
This allows the specified percent of pre-trigger data to be logged to
the data file. The trigger position is expressed as a percentage of the
data log duration.
For example, if you specified a data log duration of 30 minutes and a
trigger position of 50%, the Data Logger will log 15 minutes of pre-
trigger data to the file when the trigger occurs. Subsequently, 15
minutes of post-trigger data will then be logged to the data file.
NOTE
Once the Data Logger has been triggered, do not change the display to Scope
View; otherwise the Data Logger will stop.
Filename
Select the Filename button to specify a filename in which to save the
data. Data will be logged to this filename the next time the Data
Logger runs. If you do not specify a filename, the data will be logged
to default.dlog, which is overwritten each time the Data Logger runs.
Enter the filename in the Path\File field. Check Append date and
time at start of log to include time-stamp information in the file.
