8.7 External Input Channels
Description
Recording channels for the recorder’s external (digital) input signals.
Input
The recorder’s physical external input channels.
Calculation
The binary state of each external input is read at the selected high speed sample
rate. A filter is applied to the samples to prevent triggering on spurious state
changes, requiring that a state change be present continuously for a minimum
of approximately 700 microseconds to be considered valid for triggering pur-
poses.
Triggers
• Active state
• Inactive state
Recording
Records the state of all external input channels at the selected high speed sam-
ple rate. The input filter is not applied to the recorded data; all state changes
are included in the records.
Number of
Channels
Up to 38 External Input Channels can be defined, one for each physical input.
