7.14 Settings
All parameters required for a measurement are configured in the settings
dialog. These include the setting of the measurement type (manual and / or
trigger-driven measurement) and their characteristic values (trigger event, pre/
post trigger, interval, measurement duration, threshold value, etc.) In addition,
measurement variables and visual attributes are selected here.
7.14.1 Measure Parameter Tab
This tab defines the measurement type, duration and interval of the
measurement.
During manual measure, both the scan interval (every x-measurement is
saved) as well as the duration can be set. If the value 0 has been specified
as measurement duration, the measurement will be continuous. This
measurement can only be terminated by pressing the Stop button.
If a measurement duration greater than 0 is entered, the scan interval will be
automatically corrected if necessary, to ensure that the measurement duration
corresponds with the buffer size x of the (corrected) scan interval. An automatic
correction of the measurement duration is implemented if the scan interval is
changed so that the measurement duration (once more corrected) corresponds
with the buffer size x of the scan interval. If a continuous measurement is set
(measurement duration = 0) the scan interval is not corrected.
Example
:
Buffer size: 2,000 measurement values, scan interval: 0.01 s, then
measurement duration = 20 s.
During the triggered measure it is possible to specify a time pre-trigger as
well as time post-trigger along with the scan interval and the duration. The
configuration of a continuous measurement is not possible. The pre-trigger and
the post-trigger are specified as a time period and the measurement duration
is the cumulative sum of pre-trigger and post-trigger. If the scan interval is
changed, the time values for both, pre-trigger as well as post-trigger, are
adjusted proportionally.
