Counters
Routing a Signal to Counter
n
Gate
Each counter has independent input selectors for the Counter
n
Gate signal. Any of the following
signals can be routed to the Counter
n
Gate input:
•
RTSI <0..7>
•
PFI <0..15>
•
AI Reference Trigger (ai/ReferenceTrigger)
•
AI Start Trigger (ai/StartTrigger)
•
AI Sample Clock (ai/SampleClock)
•
AI Convert Clock (ai/ConvertClock)
•
AO Sample Clock (ao/SampleClock)
•
DI Sample Clock (di/SampleClock)
•
DO Sample Clock (do/SampleClock)
•
PXI_STAR
•
Change Detection Event
•
Analog Comparison Event
In addition, Counter 1 Internal Output or Counter 1 Source can be routed to Counter 0 Gate.
Counter 0 Internal Output or Counter 0 Source can be routed to Counter 1 Gate.
Some of these options may not be available in some driver software.
Routing Counter
n
Gate to an Output Terminal
You can route Counter
n
Gate out to any PFI <0..15> or RTSI <0..7> terminal. All PFIs are set
to high-impedance at startup.
Counter
n
Aux Signal
The Counter
n
Aux signal indicates the first edge in a two-signal edge-separation measurement.
