Taking a screenshot of an Agilent signal analyzer over a TCPIP connection

Function to connect to an Agilent signal analyzer, capture the screenshot and transfer it to MATLAB.

Description

This example uses MATLAB to capture the image on the screen of an Agilent signal analyzer and transfer it to the local PC. The example uses the TCPIP address of the instrument to connect and control the instrument using SCPI commands. For more information on the SCPI commands used to control the instrument, refer to your instrument's programmer's guide.

To execute this function, download the file to a folder on your MATLAB path and type 'saveScreenshot('127.0.0.1','myScreenshot.png')' at the MATLAB command prompt.

Note: Change the TCPIP address to the network address of the instrument.

To view the image, type 'im = imread('myScreenshot.png'); image(im);' at the MATLAB prompt.

This MATLAB example has been tested using an Agilent MXA signal analyzer but should work on all X-series analyzers and the PSA.
