Routing a Signal to Counter n Source

Each counter has independent input selectors for the Counter n Source
signal. Any of the following signals can be routed to the Counter n Source
input.
• 80 MHz Timebase
• 20 MHz Timebase
• 100 kHz Timebase
• RTSI <0..7>
• Input PFI <0..5>
• PXI_CLK10
• PXI_STAR
In addition, Counter 1 TC or Counter 1 Gate can be routed to
Counter 0 Source. Counter 0 TC or Counter 0 Gate can be routed to
Counter 1 Source.
Some of these options may not be available in some driver software.

Routing Counter n Source to an Output Terminal

You can route Counter n Source out to any output PFI <6..9> or
RTSI <0..7> terminal. All PFIs are set to high-impedance at startup.
