Two edge separator with a NI DAQCard-6024E for PCMCIA

[Henke]

Hi,

I have two different TTL-level signals available, and I want to measure the duration of time starting when one signal goes high and stoping when the next signal goes high.

How can I do this using LabVIEW 5.1 and a NI DAQCard-6024E (PCMCIA)?

Thankful for every answer.


Regards,

Henrik

Probably the best way to do this is to set up counter 0 to do triggered pulse generation and then do buffered period measurement on counter 1, with the second signal being the gate signal. In other words, the first TTL signal starts the first counter producing a pulse train and the second counter measures this pulse train until the second signal causes it to latch. Look at some of the examples for triggered pulse generation and buffered period measurement and this will probably help you get started.
