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:
•
100 MHz Timebase
•
20 MHz Timebase
•
100 kHz Timebase
•
RTSI <0..7>
•
PFI <0..15>
•
PXI_CLK10
•
PXI_STAR
•
PXIe_DSTAR<A,B>
•
Analog Comparison Event
•
Change Detection Event
In addition, TC or Gate from a counter can be routed to a different counter 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 PFI <0..15>, RTSI <0..7>, or PXIe_DSTARC
terminal. All PFIs are set to high-impedance at startup.
Counter
n
Gate Signal
The Counter
n
Gate signal can perform many different operations depending on the application
including starting and stopping the counter, and saving the counter contents.
