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.
