DESCRIPTION
The Set Scan Interval (
The first is the "normal" scan interval, used when the unit is collecting scans before the start trigger has occurred
or after stop trigger has occurred. Scans in these two regions are called pre-trigger scans and post-stop scans,
respectively.
The second is the "acquisition" scan interval, used when the unit is acquiring scans after the start trigger has
occurred but before the stop event has occurred. Scans in this region are referred to as post-trigger scans.
The
norm
The scan interval can be set to run as fast as the current unit configuration will allow. This is referred to as "fast
mode". Each of the two scan intervals can be configured as such by specifying
for the desired scan interval.
When the
configuration, if it is capable of running at the desired interval. If the unit determines that it is not capable of
running at the desired interval, it will automatically enable fast mode for the interval(s) in question. It will also
issue a Conflict Error to inform you that it is not running at the user-specified interval.
The scan interval can be programmed from a 24-hour period to a 0.1-second period in increments of 0.1 second.
If a scan interval of zero is programmed, the interval will default to fast mode. Likewise, if a scan interval is
programmed less than the unit is capable of running at, the interval will default to fast mode.
