Sample code for syncing AO with diffrent AI

[RRobertH]

I'm trying to figure out some sample code (C#.Net, VB.NEt or C++.NET) for the following

Triangle Wave of -5V to +5V to -5 Vin 0.01 V Steps (so 2002 Steps)

For Each Step of the Wave using A0 Output I want to take a Voltage Measurment on AI1.

With each step being about 1 to 2 Milliseconds long.

If I'm reading it correctly, this should be able to be done with the Internal clock, correct ?

Hi RRobertH,

Yes this should be possible with the internal clock. However, this depends on the DAQ card that you have. For example, the USB-6008/9 will not be able to do this because those cards are software-timed.

Please let me know what DAQ card you are using so I can confirm that this is possible. Thanks!

Sorry, We are using the PCI 6229 for our testing.

Hi RRobertH,

Yes, you will be able to use the internal clock.

Is their any sample code on how to do that ? (Syncing an Output with an Input) ?

Hi RRobertH,

Could you explain a little further how exactly you want your AO synced with your AI?

I do not think there is sample code available for this, but perhaps I could give you some suggestions on getting started.

I'm using the -5V to +5V back to -5V in 10mV steps to drive our driver.

The load has a 10mA Source from a External Supply.

The Load's Resistance  Will change depending on the Driver Voltage.

We need to sync the Measurment from the Analog In with the Voltage Driven 

so at -5.00, -4.99, -4.98, -4.97 ect to +5 And then Back to -5V (about 2002 Measurments), 1 Measurment for each step of the driver.

The Sweep from -5V to +5V back to -5V should take about 2 Seconds.

Hi RRobertH,

I did find an example in this location that might be useful to you:

C:\Documents and Settings\All Users\Documents\National Instruments\NI-DAQ\Examples\DotNET2.0\Synchronization\Multi-Function\SyncAIAO_DigStart

You should be able to modify it to fit your purpose. Let me know if that was helpful!
