NI-FGEN Arb Express Responsiveness

[William.Maier]

Hi,

I am trying to play around with the NI-FGEN Arb Express VI (with NI PXI-5421) in order to learn how to create my own VI to generate arbitrary pulses.  However, I am finding that when I click "Run" in the express window, my o-scope never seems to receive the waveform properly.  I am using the sample sine wave, and when I click "Run" with it set to "Start Continuous" the o-scope screen will update several seconds later with a fragment of a sine wave, and it does not continuously update.  The Test Panels for the 5421 work fine with the o-scope, so I am not sure what is going wrong.

Any help is appreciated.

Thanks,
Billy Maier

EDIT:  Never mind, the problem resolved itself.  I'm not sure how to delete threads.

Glad to hear that you found an answer to your probem, one additional piece of advice is to move beyond the express VIs as quickly as you can. The simplified interface they provide comes at a price. Banely, these VIs will nake assumptions that don`t always work in your favor.

That's what I plan on doing.  I was having a hard time getting what I wanted by just looking at the examples so I am building what I want with express and then viewing it's front panel.  That is working well so far.

Yes, that is the good way to use Express VIs: As learning tools.
