trigger config, retrigger

[General2]

Dear Sir/Madam:
I have PCMCIA NI-DAQ 6715 Card and i generate signal with 50 Hz frequency. I want to synchronize this signal with the mains voltage. I use PFI0 pin for the start trigger. It's works good, but i want want to retrigger my analog output continuously. I working with the LabView Programm (please see attachment). If I retrigger (I use AO Start in While Loop), I have problem with my signal. The signal is no more continuously (about 30 ms i don't have any signal). Is there any other method I can use to get continuosly signal?

Many Thanks

Hi General2,

I think the problem is that you are using the VIs in the wrong order.

Please look at the following VI located in the Example finder:

Open LabVIEW, click Help -> Search Examples...

Signalmeasurement - and acquisition with Hardware -> Traditional DAQ-Driver -> Analog Output -> Cont Generation - E-series D-Trig.vi

In this VI you can see how to create a continuous generation triggered by a digital trigger.

I hope this can help.

Best Regards,
