Measurements and triggers

[LabViewDud1]

Hi

I have created an output of the form ABCB (i.e., four square pulses of different amplitudes). The program is also set up to measure the corresponding input continuously. However, I am interested in the data during the period of pulse C, i.e. I wish to implement a trigger that starts the measurement everytime pulse C is on.

I'm somewhat new to LabWindows, so any suggetions are very welcome.

Best.

Hi ,

A good way to start is MultVoltUpdates-IntClk-DigStart example it will show you how to make analog output with external trigger.

Then look for the Digital generation examples , bassicly you have lots of exmples for that kind of actions.

The basic sequence is like that :

1. create a task.

2. create digital outour channel

3. define you vars & trigger.

4. start the task.

in order to define the trigger you can use DAQmxErrChk (DAQmxCfgDigEdgeStartTrig(taskHandle,triggerSource,triggerEdge));

hopes it helps
