ArmStart trigger not working with Frequency measurement on USB 6251 board

Hi there.

 

I am using a USB6251 board where I try to use a counter for frequency measurement. I want to trigger measurements on rising edge on PFI9.

If I configure the task for SemiPeriod measurement - the trigger works fine.

If I configure the task for Frequency measurement - the task never completes. (I have verified on logic analyzer that the rising edge on PFI9 happens of course)

 

Anyone encountered this issue?

 

(Using C# and NI-DAQ 8.5)
