Using Digitizer with motion card

[Project Support]

Sir,

In my application of Non-Destructive Testing of tubes using Ultrasound, I am using a motion card for controlling the motion of the Ultrasound probe (that runs with stepper motor)using the motion card. This probe moves all over the specimen under test. I am using Scope card to get the data from the probe and display and storing the waveform. Now I am moving the Probe step-by-step manner by specifying the step-increment and acquiring the data. Is it possible to acquire the data if i move the probe in the continuous manner by specifying the speed and end position alone? What are all the things i should take in to consideration to get and store the data efficiently?

Kindly help me regarding this.

Thanks,

Hello Ramkumar,

Thank you for contacting National Instruments. You should be able to use breakpoints to synchronize motion with your digitizer. Breakpoints are used to generate a trigger when a predefined position is reached. Refer to the links below for a tutorial on using breakpoints:

The above link shows you how to synchronize motion with an E-series DAQ card. You should be able to follow the same procedure to synchronize motion with the digitizer. Hope this helps you out. Have a great day!
