TTL Count

[flolite]

Hello,

I have a PCI-MIO-16XE-10 card.  I have a TTL signal coming from an encoder.  I want know the frequency of the TTL signal.  The TTL signal continue for a few minutes (I don't know if this matters, just more information).  The question is: how do I do this with labview?  (I only the most basic of labview)

Thank you.

Hey flolite,

You'll want to use the counter input of the 6030E (PCI-MIO-16XE-10).  You can look through the examples in the LabVIEW Example Finder to see how such an acquisition could easily be done.  Look under Hardware Input and Output >> DAQmx >> Counter Measurements >> Digital Frequency.  The first example you'll see shows how to measure frequency on the counter's default input terminal.  Additionally, this example could be extended to measure frequency with other measurement methods for different frequency and quantization error requirements.

Check it out and post back if you have any further questions
