Interactive Trigger; Over Range Detector; Pulse Frequency - HBM SomatXR CX23-R User Manual

4 Setting up and running a test

After true - false edge: Reset on the sample after the trigger channel
o
transitions from TRUE to FALSE. If the Integrate only when true option is not
selected, then the output sample after the TRUE to FALSE edge is the sum
of the initial value and the scaled input sample.
NOTE
When using the Integrate only when true option, the Reset mode is limited to
After true - false edge.
Reset when sum exceeds: When selected, the integration resets to the initial
o
value when the absolute value of the integrator sum exceeds the entered value.
4.4.9 Interactive trigger
The Interactive trigger channel provides a means to trigger
computed channels directly from the
eight Interactive triggers.
Trigger index: Set the index from 1 to 8 to identify the trigger during a test run.
Invert trigger: If selected, the trigger logic is inverted.
4.4.10 Over range detector
The Over range detector provides a simple user interface to allow users to determine
if any selected channels in the test have exceeded a defined Alarm min / max value.
The output is a logical channel that is updated at the user selected test engine frame
rate. The output is set to Boolean true (i.e., 1) when any input channel data sample
exceeds a defined Alarm max or Alarm min value in the test engine frame period;
otherwise, the output is set to Boolean false (i.e., 0). The output can be fed into a one
or more Digital Output channels to drive an LED indicator.
This computed channel is provided for use with analog sensor channels primarily;
however, any sequential input channel or computed channel can be selected as long
the one or both of the Alarm min / max parameter values are defined.
When a channel trips an alarm, a message is generated in the system Log file that
starts with "Over range" to simplify searching the Log file for the messages. Only one
Alarm max exceedance and one Alarm min exceedance message will be generated
for each channel over the duration of a test run. This allows the user to determine
which channel(s) have tripped an alarm limit, while preventing the Log file from
becoming saturated with redundant error messages.
Input channels: Select the desired set of input channels. The input channels can
have different sample rates. There is no limit on the number of input channels.
4.4.11 Pulse frequency
The Pulse frequency computed channel is designed to measure pulse frequencies,
primarily in conjunction with
input channel for falling edge and rising edge transitions. The pulse period is updated
based on the time between rising-to-rising edges and falling-to-falling edges.
