Hi all,

I am currently working with Tek DPO3054 scope and want to extract the waveforms for analysis in MATLAB. I want to capture the full record length rather than just the screen. My first approach was to use a USB stick to save a (.csv) file and import the data into Excel. The problem is that saving the data to the USB takes too long. In hoping that a direct link to the computer would be faster, I downloaded VISA drivers and managed to talk to the device using MATLAB. However, when I issued the readwaveform() command, I noticed that it only captured whatever is on the screen. How can I ensure that I capture the complete record length?

Thanks!
