Issue Details

While using 100Khz timebase in PCI-6602 for counter measurement, I got the error below. However, the specification mentioned that 100kHz can be used for counter measurement. How can I use 100kHz timebase in PCI-6602?

Solution

For PCI-6602, there is only one PFI input available to obtain 100 kHz timebase, which is PFI3.

The timebase clock can be routed to the PFI line programmatically in LabVIEW using the DAQmx Connect Terminal VI .
