Hello, I've donwloaded the labview driver (plug and play) for Agilent DSO1012 running in Labview 8.2. The oscilloscope is connected via USB to computer. I was intended to acquire waveform continuously by running 'Agilent DSO1000 Series Acquire Waveform Continuously.vi'. The vi can only be running for less than 20 seconds and it was always terminated by the following error:Error -1073807339 occurred at VISA Read in Agilent DSO1000 series.lvlib:Wait for Acquisition Complete.vi ->Agilent DSO1000 series.lvlib:Read Waveform (Single).vi->Agilent DSO1000 Series Acquire Waveform Continuously.viPossible reason(s):VISA: (Hex 0xBFFF0015) Timeout expired before operation completed. Anyone could help me? I am new in controling instrument using Labview. Rui DU

Do you have your context help window open and did you read what it says when you place your mouse over the Read Waveform function? If your scope is not triggering and acquiring, then you will get the timeout error. If you can acquire a single waveform and display it, you might need to add some scope configuration functions to the example you are using. I would assume you already changed the maximum time control to higher values.

VISA Read error in Agilent DSO1012A oscilloscope, time out expired before operation

Solved!

Instead of choosing at random various VIs to run, why don't you try reading the programmer's manual to understand what commands are being sent by these VIs and what these commands actually do?
