hi all,
im a student performs my final project. Briefly, i generates pulses with pulse generator , square wave 5V/ 100hz, to a transmitter-receiver pair of ultrasonic
transducers.
My aim is to measure the distance between those transducers. I want to synchronize the pulse generator triggering with the data acquisition from the ultrasonic
receiver, while pulse generator exceeds 4V (ch 0) , record x samples (ch 2). i tried to sample the two signals( square wave and Ultrasonic wave) simultaneously
and noticed for time delay between them.
i have labview 2010(student edition) and advantech PCI1714UL ( 4 single-ended analog input channels, up to 10Mhz sample rate) with advantech vi's for labview.
thanks alot,
gal.

What is the question?

how can i sample the Ultrasound signals exacly( with the error of the A/D) from the same point while using the Ultrasound pulse generator and labview?
thanks alot, Gal.

Hi gal.co,
Sounds to me like you are trying to achieve triggerable, synchronized input and output?
I suggest looking through this white paper: Timing and Synchronization Features of NI-DAQmx.
Also, National Instruments does not support the third party Advantech devices. If you require further assistance with the Advantech VIs, I suggest contacting Advantech. It does not hurt to post on the National Instruments forums, however, as other National Instruments customers use various third party drivers and could offer assistance.
