DASylab. Get time difference in milliseconds.

[Nils]

Hello,

I'm quite new to DASYLab and is searching for a way to save / get / extract time difference between two events. The difference is 3 to 5 ms and thus cannot use module Time Base as it only outputs in seconds.

I have TTL signals for the two events and the time stamp in CSV. 

Do anybody know how to measure the time difference?

 

Thank you!

Nils

Assuming you have a device like the USB-1608G, the digital input is too slow to record the pulses. But you could use two analog inputs to digitize the two pulses at a high sample rate. Connect the analog input signals to a Combi trigger module set to trigger using two signals. Set both the start and stop conditions to the rising edge. One signal will make the Combi output go high and the other will set it back low, producing a pulse. Then use the Pulse Analysis module to measure the pulse width. The whole thing will be clocked using the device time base, which can be set relatively high.
