Send trigger, wait for two triggers to come back and update analog output

[ErikHaverkamp]

Hello,

I am working with LabVIEW 7.1 and the DAQ unit I am using is a USB-DAQ 6211

I have to solve the following problem:

1) AO1 to 0V

2) Send TTL trigger to two external instruments (Keithley 2000's)

3) Wait for both the measurement complete signals of these instruments to come back (TTL)

4) increase AO by 0.01V and go to step 2 (untill AO=5V)

I am running into problems because of the two measurement complete signals, because they really come on different times. And also the triggering of the Analog Output strikes me with troubles, it should be retriggerable but how? Ah and third: the time between the measurements is about 1ms so it should also be relatively fast.

Could somebody give me ideas of where and how to start with this. I am not very experienced in DAQmx (I stopped using LabVIEW at version 5.1). I would already be great if I got some tips of how to handle!

Thanks in advance,

Erik

I am very sorry I accidentally posted this question to the LabVIEW forum, It should have been in the multifunction DAQ forum. I reposted it there, please don't react on this post!

Excuse me,

Erik
