Hi there,
I have a PCI 6229 DAQ installed in my PC and I am accessing it using the SCB-68A breakout board. I am struggling with generating a Pulse Train using either of the counters on-board. Here is how I have tried it:
- Using the Test Panels in NI MAX, I have tried to Counter Output on CTR0OUT (PFI12) and CTR1OUT (PFI13) without providing any signal to CTRxTRG or CTRxSRC pins. Checking by connecting an oscilloscope probe between CTRxOUT and DGND, I get no output. I am using the default values for Frequency (1000 Hz) and Duty Cycle (50%).
- Using NI MAX, creating a task CouterOutput is of no use either. Choosing either of the counters in Continuous Pulses with 1000 samples, gives nothing. Other options have been explored in this task too but to no avail.
- I have successfully tried other functionalities of the board such as Analog Output, Edge Counting (using either of the counters), so there is something wrong only with the Counter Output.
Could it be that my assumption of Pulse Train being RSE is wrong? Am I trying to measure it correctly? Or do counters require triggers to generate output?
Looking forward to useful directions.
