I bought this device to automate current and battery life testing for my projects. I use Python, pyVISA and Octave on Linux to collect, plot and report results; Setting up the interface and working with it was trivial. The device works flawlessly with all my devices (HP E3640A, 33120A, 34401A and 54501A). I am very happy with this purchase; I plugged it in and it just worked. Really high praise.
