Introduction for waveform generation module, PC-based platform providing remote control


Tektronix recently announced a method that enables engineers to control signal sources and generate waveforms in a simpler and more seamless manner. The new PC-based SourceXpress platform allows for the easy configuration, synchronization, and remote control of multiple arbitrary waveform generators, and introduces a multifunctional plug-in architecture for waveform generation modules, enabling expansion into a wide range of applications from high-speed serial and coherent optics to RF and wireless.

The ability to generate, produce, or replicate ideal, distorted, or "real" signals is essential when designing, testing, or operating complex components, systems, and experiments. The Tektronix AWG70000 series arbitrary waveform generator produces virtually unlimited analog or digital signals with up to 50 GS/s and 10-bit vertical resolution using direct waveform synthesis.

The main challenge to date has been continuously addressing the rapid changes in the consumer electronics industry and the wide range of signal source applications. SourceXpress simplifies the development of new waveform generation modules through its plug-in architecture, thereby further reducing the time required to launch new applications. In the future, Tektronix plans to release an expansion module library to complement the newly released Generic Pre-Compensation plugin and Multitone & Chirp plugin together with SourceXpress.

Jim McGillivary, General Manager of RF and Component Solutions at Tektronix, stated, “SourceXpress applications take signal source instrumentation control and waveform generation to a higher level, enabling the full performance of AWGs. Instead of having a large-scale software platform for various applications, we are developing smaller waveform generation plugins that can be integrated into the AWG70000 user interface or PCs using SourceXpress. Therefore, customers can select only the modules needed for specific applications without having to spend money on unnecessary features.”

SourceXpress, which runs directly on a PC or equipment, features an interface identical to the default GUI of the AWG70000 series. Many applications require multiple signal sources, all of which must be precisely tuned. Using SourceXpress allows you to control multiple signal sources from a single location, enabling faster test setup and execution.

Generate correction coefficients with a standard pre-correction plugin

When generating waveforms to test broadband receivers, it is important to generate signals with a flat frequency and linear phase response on the test equipment. The Generic Pre-Compensation plugin for SourceXpress generates compensation factors that can be applied to waveforms to obtain a flat frequency and linear phase response. This plugin works with various waveform types and applications, including RF, IF, IQ, and NRZ signals.

A defining feature of RF and signal generation applications is the ability to create clean chirps, tones, and notches. The Multitone & Chirp plugin for SourceXpress is suitable for a wide range of military, aerospace, and RF applications. This plugin can be used to generate NPR (Noise-to-Power Ratio) tones using a desired set of start and end frequencies and intervals. Unwanted frequencies can be eliminated by setting selectable start and end frequencies. When generating chirps, users can choose between "high-low" or "low-high" frequency sweeps and define chirp characteristics based on sweep time or sweep speed.

The SourceXpress platform can be downloaded for free from http://kr.tek.com/sourcexpress, and Generic Pre-Compensation plugins and Multitone & Chirp plugins are currently available worldwide. Domestic sales prices can be inquired about directly with Tektronix Korea (main number 6917-5000).
