Generate analog values using 6052E and wait for a specific time between each generation:

[Mizar]

Hi:

I have to generate voltage values from 0 - 10 Volts using PCI6052E.  However, I have to wait a specific time between each voltage value generation.  Anybody knows how I can achieve this?

Look at the shipping example called Gen Voltage Update (assuming you are using DAQmx). You can put the DAQmx Write inside a for loop and auto-index an array of step values though the loop. Add a Delay function and you are done. You could get a bit fancier and use a while loop and exit if there is an error. Other shipping examples show that. You would just have to add another condition to stopping the loop. Instead of (or in addition to) get the array size and stop the while loop when the iteration count is greater than the number of elements in the array.

Hi:

I am not using DAQmx.  How do I go about this hurdle?.  I am using LABVIEW 6.1.

Thanks,

Then you can just use AO Single Update in a loop. A bit higher level function is AO Update Channel. You can also look at the shipping example called Generate 1 Point on 1 Channel.

Hi:

I have to generate a sine Wave with a particular DC offset.  Have tried many ways, but have not been successful.

Mizar,,.

[Dennis_Knutson]

You haven't tried anything in this example. You just have to use the Sine Pattern function and add an offset.

Hi Dennis:

If I have to do the stepping for the amplitude based on my array (from the VI you had helped me out with last week) how do I go aboit it?

Thanks,

Mizar

[Dennis_Knutson]

This would be one way if I understand your question correctly. With each iteration of the outer for loop, it would take one amplitude value and step though it based on how many samples you define for the sine wave.

Hi Dennis:

Thanks a lot!.  That works.  However it asks for a file name everytime it iterates.  Can I move the file dialog anywhere else?

Mizar,

[Dennis_Knutson]

Yes. Move outside the outer most for loop if you want a single file for every iteration.
