Using RTSI Terminals as Timing Input Signals

You can use RTSI terminals to route external timing signals to many
different X Series functions. Each RTSI terminal can be routed to any of
the following signals:
•
•
•
•
•
•
•
•
•
•
•
•

Most functions allow you to configure the polarity of RTSI inputs and
whether the input is edge or level sensitive.

RTSI Filters

You can enable a programmable debouncing filter on each PFI, RTSI, or
PXI_STAR signal. Refer to the
more information.
