ABOUT internal timing/counter of DAQ

[1170]

I am using DAQ 6014 to get the analogue waveform? Does DAQ6014 have any internal timing and counter which I can use to sample the data of waveform? If not, how to do this? I checked user manual and also don't know is the CTR, ICTR or GCTR can be used in DAQ 6014?

The NI 6014 has an internal clock that you can use to set the scan rate of analog input. There are several example programs that use the LabVIEW or NI-DAQ function calls that illustrate how to set the scan rate of an analog input acquisition.

In LabVIEW, the AI Start VI has a scan rate input with which you can control the rate of analog input. If using NI-DAQ function calls, the DAQ rate function has the rate input parameter with which you can set the scan rate of the input acquisition.

The 6014 also has two onboard counters that can generate a digital pulse train and you could use that pulse train as a clock for the analog input. But, if you are just wanting to set a scan rate for the analog input, you won't need to use a counter on the device. I hope thi
s helps.

Thank you for your answer, but I am using labwindow/CVI, so how can I find the function you mentioned and where can I find the examples for aquire a number of waveforms from AI input port.
