3. Introduction Scope is utilized as a primary testing instrument for Time Domain signals. Its multichannel and coherent sampling capabilities makes it useful for a variety of applications in different and complex engineering disciplines. Automation of the scope is essential for an efficient utilization of the platform. MATLAB, in conjunction with its Instrumentation Control Toolbox , is an ideal SW platform to both control the instrument parameters and acquisition properties, as well as and post-process the acquired data arrays.

4. Project’s Goals Remote control of platform settings Capture and import Data matrices from the scope channels directly into Matlab On-line data processing Building user-friendly GUI

5. Proposed methodology Building a dedicated, GUI-assisted, interface scripts for an embedded device control and using the vendor-specified SCPI commands Utilization of the Matlab Instrumentation Control Toolbox as the SW platform Using Matlab signal-processing and display functions to on-line analysis the captured waveforms and provide graphical displays of the post-processed functions

6. Settings of Scope Channels – choosing and activating the active channels Scaling – controlling the display Horizontal (X) and Vertical (Y) axis values Building an embedded AGC feature Setting scope sampling rate Setting acquired traces record length Setting trigger options

7. Signal processing CW waveforms – calculations of Signal-to-Noise (SNR) ratio Clock waveforms: calculations of Jitter parameters

8. GUI Graphicaluserinterface
