Duty cycle measurement using RLP

[Fv1234]

Hi All,
I 'm using a PCI-6229 in RTX environment and, I would like to measure a duty cycle.
Is there any exemple file?
 
Your help is welcome

Hello Richard K,
I sorry but I would like to program my board with register level because I'm in RTX environment. I can start with gpctex3.cpp but I have no informations to do a buffered semiperiod measurement.
Thanks for your help.

I used also the <a href="http://digital.ni.com/manuals.nsf/websearch/E929838D7D0EE50986256728007FEADF" target="_blank">DAQ-STC Technical Reference Manual</a>
Thanks for your help

Hello Jeremy,
My acquisition works fine but sometime, the first acquired point is the High level and sometime, the first acquired point is the Low level. I created a semi period task with MAX and with each acquisition, the first acquisred point is the same level.
In my code, I programed the gate polarity at 1.
Do you know what is the source of my problem?
Thanks for your helps

Hi Tom,
It works, I configure the second gate and now every time, my acquisition starts at the same level.
Thanks a lot

Hi Fv1234,
I'm trying to do the same thing : measuring a PWM with a 6229 on a RTX OS, do you have son code example ?
Thanks for your help.
