Analysing Continuous Cycle Data

[danieleaston]

Hi there,

I am running a cyclic machine which I need to process some signals on a per cycle basis.

I'm currently using a USB 6009 DAQ device to measure 2 signals on differential analogue input channels.  I have a rotating slot and photodetector which I can use to create a pulse at a set point in my cycle.  I need to do some maths processing on the signals on a per cycle basis using the rising edge of the pulse as a reset trigger each cycle.  I have spare analogue, digital and counter/trigger channels on the USB 6009 device but am not sure which channel is best to use for the reset and how best to implement a solution in Labview (version 8).

Any help is much appreciated

Hi Daniel,

It will be quite simple to create a solution for this using LabVIEW.  What have you being using up until now?  Are you using any other hardware/software?  Do you want your complete solution to only use the 6009 and LabVIEW? 


If you already have a copy of LabVIEW, the best place to start would be the NI example finder.   If you go to help then find examples.   From there you can select browse,   Hardware input output, DAQmx.  Then in there you will see examples which may help.

Please write back if you need further help.

Rgds,

Seamus,

I've looked through the examples but most are too complicated for me - took over Labview programming responsibilities from a (since departed) collegue in January.  I haven't had any training but am slowly getting to grips with Labview.

I've reposted this question (with more detail) in the Labview forum as I've solved the DAQ issues I was having and am confident my input signals are all OK.  I just a bit of help to lick the processing and analysis bit into shape
