[Question] PCI-6220: digital level at the pause of a continuous impuls train with external trigger

[Wei_X]

Hallo,

I'm trying to use a PCI-6220 card to generate a continuous impuls train which will be paused at an external trigger. I've used the example code in the example library to generate the impuls train. The idle state of the impuls train is set to be high. But I figure that die digital level at the pause is sometimes high and sometimes low. I suppose that the level stays at the exact time when the pause begins?

Is my assumption correct? Is there any way to let the impuls always pause at the idle state, like it will then be paused after a full impuls is finished? Any tips or links will help. Thanks in advance.

Yes your assumption is right. The output is latched to the last set value.

If you are generating the pulse through the counter,  setting the Idle state in Create Virtual Channel.vi   doesnt help?

Thanks Vsh,

but the setting of idle state doesn't work. Like I said, I have set the idle state to high in Creating the virtual Channel, but the output is still sometimes high and sometimes low.
