LeCroy 9400A Driver

for MATLAB

System requirements :

MATLAB R2010a or later
Windows or Mac OS
Prologix GPIB-USB
LeCroy 9400A or 9400

License : Freeware

VERSION : 1.2

A new driver for an old oscilloscope.

Autoscale High-Resolution Display : The function returns two figures (with up to 25’000 points per channel). The first one displays two channels on the same graph, and the second one displays one channel per graph. The two figures use autoscale (for x and y axis).

Data Processing : The function computes only the mean and RMS values of each channel, but all the data are saved in the workspace. So you can create your own signal processing.
