Tektronix has introduced a more convenient and flexible way for engineers to control signal sources and generate waveforms. The new PC-based SourceXpress platform allows users to easily setup, synchronize, and remotely control multiple arbitrary waveform generators. This tool introduces a versatile plug-in architecture for waveform creation modules that will span a wide variety of applications from high speed serial and coherent optical to RF and wireless.
The ability to create, generate, or replicate ideal, distorted, or "real-life" signals is essential in design, testing and operations of complex components, systems and experiments. The Tektronix AWG70000 Series of arbitrary waveform generators use direct synthesis to create a virtually unlimited number of analog or digital signals with up to 50 GS/s and 10-bit vertical resolution.
A key challenge to date, however, has been keeping pace with the rapid change in the electronics industry and the wide variety of applications for signal sources. With its plug-in architecture, the SourceXpress simplifies development of new waveform creation modules for faster time to market as new applications emerge. Over time Tektronix plans to roll out an extensive library of modules to compliment the Generic Pre-Compensation and Multitone & Chirp plug-ins introduced today alongside SourceXpress.
Running on either a PC or an instrument directly, SourceXpress features the same interface as the native GUI of the AWG70000 series. Many applications require multiple signal sources, which all must be precisely coordinated. With SourceXpress uses can control multiple signal sources from one location for faster test set up and execution.
Generic Pre-Compensation Plug-in - When creating waveforms for testing wideband receivers, it is important that the test equipment generate signals with flat frequency and linear phase response. The Generic Pre-Compensation plug-in for SourceXpress creates correction coefficients that can be applied on waveforms to obtain flat frequency and linear phase response. The plug-in works for a variety of waveform types and applications including RF, IF, IQ & NRZ signals.
Multitone & Chirp Plug-in - The hallmark of RF and signal generation applications is the ability to produce clean chirps, tones and notches. The Multitone & Chirp plug-in for SourceXpress is ideal for a wide variety of military, aerospace, and RF applications. This plug-in can be used to create noise power ratio (NPR) tones with a set of desired start and end frequencies and spacing. Frequencies can be notched out by setting the start and end frequency of choice. When generating chirps, the user can decide between "high to low" or "low to high" frequency sweeps and define chirp characteristics by sweep time or by sweep rate.
