What is the onboard memory size of your NI 5124? The available options are 8, 32, 256 and 512 MB. What is the rate at which you are reading from digitizer and how many samples?
You should read fast enough so that whatever onboard memory is available is not filled up.
Under NI Example finder you will get niScope EX Fetch Forever.vi which you can use to coninuously acquire.

Hello jacklkb,
It depends on the sampling rate specified for acquisition and how many samples you are reading. The digitizer card is capable of 200MS/s sampling rate. With 256 MB buffer, ideally you should be able to capture with maximum capacity.
