| Description |
MATLAB is a software environment and programming language with over 1,000,000 users and supports Tektronix Arbitrary Waveform Generators through its Instrument Control Toolbox.
One of today’s most challenging design problems in RF technologies, as well as other wireless applications, is the creation of stimulus signals that can fully exercise a prototype. Complex high-frequency modulated signals with jitter, spread spectrum clocking, and other time-variant effects require a benchtop of pulse, function, modulation and RF generators. Using MATLAB to generate such a signal and output it through a Tektronix Arbitrary Waveform Generator replaces the need for all that equipment.
The ‘generate_arb_waveform_Tektronix’ script connects to the Tektronix AWG, resets it, puts the waveform onto channel 1 of the instrument by calling the ‘chirp_signal’ function, enables channel 1 output, and disconnects the instrument. This ‘generate_arb_waveform_Tektronix’ script was generated by Test & Measurement Tool, a graphical tool provided by Instrument Control Toolbox that allows the user to configure and control instruments in MATLAB.
To execute this example, extract the files from the zip file and type ‘generate_arb_waveform_Tektronix’ in the MATLAB command window. Notes: Change the IP address in the generate_arb_waveform_Tektronix.m file to the IP address of the AWG. If the Signal Processing Toolbox is not installed, replace the CHIRP function in chirp_signal.m with a different function.
