
Connect the signal source’s positive terminal Ch1 of a signal source to
PCIe/PXIe-5211 counter0’s edge counting source (CTR0_Source, Pin#65),
negative terminal to the ground (GND, Pin#66) as shown in
Table 2-15 Pin
Defination . (CTR0_Source, GND) consists of an edge counting counter input.

Set the signal source Ch1’s output to squarewave signal (f=1Hz,
