waveform generator

[Roxanne]

Hi David,

I have read that introduction. What I cannot figure out is when playing an .hws file on the card as opposed to 1D arrays generate din NI examples, I can see the .hws signal on the output and the also on the acquisition channel (physically routing a signal for test). But somehow the acquired data always look as N samples of one value (0,1), I am using a slightly modified NI example, for simultaneous generation and acquisition.

I have tried using "Multi Record: WDT" but still the same issue.

Any idea?

Thanks for your help,

Roxette

Seems all programs work fine once I shut down and restart the computer (NI card issue?).

Hi Roxette,

It may be an issue with the card.  There may have also been an issue with properly clearing the resources.  Regardless, what platform was this card for?

Hi David,

This is on Windows7.

My apologies.  I meant is the 6551 a pci or a pxi card?

It's a PCI.

So I don't think this is an RMA, but if the behavior happens again try reseting the device in MAX.  You can also try running examples if it happens again to see if the results are as expected.  If the issue persists you may need to post some more detailed information on how you have the card connected.
