My question has to do with analog input and triggering? Does anyone have any suggestions on how i can improve the attached vi so it can trigger on a 50kHz ten cycles pulse after the pulse has been sent out on the output?

[JrodMillar]

Could you just look at this vi and tell me if i am doing anything wrong? I get errors that are different each time I change something. here are the inputs I am using

Output Side:
amplitude = 1
freuency = 50kHz
Sampling Frequency = 1MHz
3 of Samples = 200

Input Side:
Input Buffer 4000
trigger type = analog
pretrigger = 5
edge or slope = rising
scan rate = 500kHz
# of scans = 2000

Conditional Retrieval
mode = on
slope = rising
skip count = 0
level = .1
offset = 0
hysteresis = 0

So what we want to do is capture the ten
cycles of the 50k output pulse on the input and need to store that so we can plot it later, do you have any suggestions. we are using the PCI-MIO- 16E board.

Thanks,
Jarrod

1) Toss the sequence frames (no flames please).

2) Set you read and have it ready to trigger before oing the output.

3) After the output, go back and read the data that is waiting for you.

4) If you have errors tell us what they are and under what conditions they occured.

End of Ben's suggestions for now.
