Digital trigger by PF1 of 5133

[alex.]

1. May I know how to program 5133 trigger by PF1 in ni-scope

2. As learned, the PF1 is digital trigger. Will it trigger when voltage change from 0 to 3V only, or when the voltage is 3V, it will keep triggerring all the time. If it is in the second case, is it true the next trigger will start as soon as the 1st data is fetched. Or will it wait the first data to be fetched or just overwrite again and again.

3. I've 2x5133, the 2 PF1 will connect together, may I kow in software how to gurantee to fetch the data triggered at same time, how to make the program.

Thanks

I tried to use the attached program, but got error as the attached screenshot.

The most challenge is how to fetch the same time triggered data.

Thanks.

After change the external trigger source to PF1, it works.

Now the 2x5133 should be able to be triggered at same time, but I am not sure if the fetched data are belong to the same triggering.

May I know how to verify it, thanks.
