[. . . ] When used in conjunction with RFXpress the AWG7000 Series supports a wide range of modulation formats and simplifies the task of creating complex RF waveforms. The AWG7000 Series instruments provide customers with ways to generate fully modulated baseband, intermediate frequency (IF) signals, or directly generated RF waveforms. Wideband RF Signal Generation Creating RF signals is becoming more and more complex, making it more difficult for RF engineers to accurately create the signals required for conformance and margin testing. When combined with RFXpress, the AWG7000 Series can address these tough design challenges. RFXpress is a software package that digitally synthesizes modulated baseband, IF, and RF signals taking signal generation to new levels by fully exploiting the wideband signal generation capabilities of the AWG7000 Series arbitrary waveform generators (AWGs). [. . . ] Electronic environments have noise, jitter, crosstalk, distributed reactances, power supply variations, and other shortcomings. A real-world digital "square wave" rarely resembles its theoretical counterpart. Since the AWG7000 Series is an analog waveform source it is the perfect single-box solution that is used to create digital data streams and mimic the analog imperfections that occur in real-world environments. The AWG7000 Series uses direct synthesis techniques which allow engineers to create signals that embody the effects of propagation through a transmission line. Rise times, pulse shapes, delays, and aberrations can all be controlled with the AWG7000 Series instruments. When used in conjunction with the SerialXpress software package, engineers are provided control over every aspect of their digital signals reaching speeds of up to 6 Gb/s. This is exactly what is needed for rigorous receiver testing requirements. SerialXpress is an integrated SW tool that enables AWG7000 Series instruments to create a variety of digital data impairments such as jitter (Random, Periodic, Sinusoidal), noise, pre/de-emphasis, duty cycle distortion, Inter-symbol Interference (ISI), Duty Cycle Distortion (DCD), and Spread Spectrum Clocking (SSC). The transmission environments of both board and cables can be emulated using touchstone files uploaded into SerialXpress. The AWG7000 and SerialXpress solution also provides base pattern waveforms for many of today's high-speed serial applications such as SATA, Display Port, SAS, PCI-E, USB, and Fibre Channel. For high-speed serial applications the AWG7000 Series offers the industry's best solution for addressing challenging signal stimulus issues faced by digital designers who need to verify, characterize, and debug complex digital designs. The file-based architecture uses direct synthesis to create complex data streams and provides users with the simplicity, repeatability, and flexibility required to solve the toughest signal generation challenges in high-speed serial communication applications. 4 www. tektronix. com/awg7000 Arbitrary Waveform Generators -- AWG7000 Series Characteristics Definitions Specifications (not noted) ­ Product characteristics described in terms of specified performance with tolerance limits which are warranted/guaranteed to the customer.
