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.
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:
•
(USB-6210/6211/6215 Devices)
PFI <0..3>
•
(USB-6212/6216 Devices)
PFI <0..15>
•
(USB-6218 Devices)
PFI <0..3>, PFI <8..11>
•
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)
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 output PFI terminal.
Counter n Aux Signal
The Counter n Aux signal indicates the first edge in a two-signal
edge-separation measurement.
Routing a Signal to Counter n Aux
Each counter has independent input selectors for the Counter n Aux signal.
Any of the following signals can be routed to the Counter n Aux input:
•
(USB-6210/6211/6215 Devices)
PFI <0..3>
•
(USB-6212/6216 Devices)
PFI <0..15>
•
(USB-6218 Devices)
PFI <0..3>, PFI <8..11>
