Issue Details

I'm trying to create a DAQmx-Task for a counter measurement with type "Frequency" for a NI 9361. If I set the measurement method to anything but "Dynamic Averaging" I receive Error -200077.

Solution

The NI 9361 only supports "Dynamic Averaging" as a measurement method for frequency measurements. This is documented in the Choosing a Counter Frequency Measurement Method Knowledgebase.
For other measurement methods you need different hardware. You may use the internal counters of your cDAQ-Chassis instead.

Additional Information

You may consider using a pulse width measurement instead of a frequency measurement. Still, this is not applicable for all applications.
