Sending waveform to function generator?

[Azazel]

Hello all,

I am using an agilent 33205A function generator and require it to use a special driving waveform.  Currently I load the waveform using this HP Benchlink software.  I would like to automate this in the startup of my vi.  Is there a way to download a "home-grown" waveform to the function generator using labview? 

Thanks,

Azazal

If you're using the driver from here, then use the function called ag33xxx - Arbitrary Wfm Ops. You will have to create the waveform in the form of a 1D array. Look at the high level example called ag33xxx - Arb - Application. I don't see a function in the driver that allows you to output a defined waveform so you may want to look in the instrument manual to see if there is such a function. If there is, then it should be a simple matter to read it and then place the values into LabVIEW as a constant or something you read from file.

Hey,

Even I have to do similar stuff. I have to send  arbitrary waveforms to 33120 using labview one after another for automated testing of line drop out test.Is there any way to send arbitrary waveforms through labview?

What part of the answer don't you understand? The function I mentioned will transfer a waveform to the instrument. What you will have to do is write some code to read the waveform from file and pass it to the Data input of the function. I think you can use BenchLink to create the waveforms and save them.
