How to set the time interval for data obtain through labview via write measureme

[qinn]

I'm need to programme to obtain data from oscilloscope. Currently my laptop able to communicate with Agilent DSO6014A oscilloscope via USB. I'm include the write measurement in mty program and save the data in .lvm file. But the time interval in the data are too small which is in micron seconds. Is there a way to modify the interval values?

Hi,

can you post your code or an image.

I suppose writing to the file is fast, so you can use any of the timing vis to wait (msec) in your loop.

The attached file is the capture of my diagram. Thanks.

Looking at your screen grab you could either reduce the loop rate by increasing the ms delay, or if you need the high loop rate for your other processing you could put the log vi in a case structure and trigger it every x ms or loop iterations

Hope this helps

The dt that is recorded in the file is the sample rate of the scope. You are not setting the sample rate and are depending on the auto-setup function of the scope. Use the function to set the horizontal to whatever you want and whatever the scope supports.
