You can control and acquire data from optical and RF power meters directly from MATLAB using Instrument Control Toolbox. Because you can control the instrument directly from MATLAB, there is no need to save the data and import it at a later time. You can also create graphical interfaces for collecting and analyzing data, visualizing the results, and automating tests.
Using SCPI commands described in the operating or programming manual for your optical or RF power meter, you can control and acquire data from any power meter over any of these supported interfaces:
Many manufacturers of optical and RF power meters supply industry-standard instrument drivers that you can use directly from MATLAB. Instrument Control Toolbox provides connectivity through instrument drivers such as:
