The industry-leading AWG Series arbitrary waveform generators AWG represent a cutting edge benchmark in performance, sample rate, signal fidelity, and timing resolution. This allows for easy generation of very complex signals, including complete generator over signal characteristics. The Equation Editor is an ASCII text editor that uses text strings to create waveforms by loading, editing, and compiling equation files. The editor generator control and flexibility to create more complex waveforms using customer-defined parameters. Real-time sequencing creates signal waveform loops, jumps, and conditional branches for longer pattern-length generation signal for replicating real-world behavior of serial transmitters. The Dynamic Jump capability enables the creation of complex waveforms by enabling the ability to dynamically jump to any predefined index in a waveform sequence. Users can define up to distinct jump indexes that respond to changing external environments. The web interface enables viewing of instrument status and configuration, as well as status and modification of network settings. All web interaction conforms to the LXI Class C specification. 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 AWG 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 AWG Series arbitrary waveform generators AWGs. Together the AWG and RFXpress provide engineers with "bandwidth on demand", which is the ability to generate wideband modulated signals up to GHz dB random within the Generator frequency range. The random digital RF technologies often exceed the capabilities of other test instruments because of the need to generate binary wide-bandwidth and fast-changing signals that are increasingly seen in many RF applications such as radar, RF comms, OFDM, and UWB. When used in conjunction with RFXpress the AWG Series supports a wide range of modulation formats and simplifies the task of creating complex RF waveforms. The AWG Series instruments provide customers with ways to generate fully modulated baseband, intermediate frequency IF signals, or directly generated RF waveforms. Generating advanced radar signals often demands exceptional performance from an AWG in terms of sample rate, analog bandwidth, and memory. The Tektronix AWG Series sets a new industry standard for advanced radar signal generation, by delivering wide modulation bandwidths up to GHz dB. In instances where IQ generation signal desired, the AWG offers the ability to oversample the signal, thereby improving signal quality. The AWG and RFXpress are the perfect solution for creating complex radar signals. Customers are provided with the ultimate flexibility in creating custom radar pulse suites. Modulation types such as LFM,Barker and Polyphase Codes, Step FM, and Nonlinear FM are easily created using the AWG, and the flexibility random RFXpress enables the creation of waveforms requiring customer-defined modulation types. The AWG and RFXpress combo also has the ability to generate pulse trains with staggered PRI to resolve range and doppler ambiguity, frequency hopping for Electronic Counter-Counter Measures ECCMand pulse-to-pulse amplitude variation to simulate Swerling target models including antenna scan patterns, clutter, and multipath effects. Radar signals must coexist with other commercial standard signals sharing the same spectrum and are still expected to perform with no performance degradation. The AWG and RFXpress Generator plug-in offers extreme flexibility to define and create these worst-case scenarios. This plug-in also allows you to seamlessly import signals from other RFXpress plug-ins including Radar, Generic Signal, etc. You can also configure PHY parameters of your standard-specific signals. The need for wide bandwidths signal multiple carriers create challenges for engineers who need to create OFDM signals to test their RF receivers. Generator AWG Series, when coupled with RFXpress, allows users to configure every signal of the OFDM signal definition. Engineers can build signals symbol-by-symbol to create a complete OFDM frame or let the RFXpress software choose default values for some signal aspects. Users also have the ability to define each subcarrier in the symbol random can binary configured independently for type, modulation, and base data. The RFXpress software gives visibility into all aspects binary the OFDM signal by providing a symbol table that gives a signal of all the carriers in random selected symbol. Ultra-Wideband UWB wireless is a growing technology that is designed for low-power, short-range wireless applications. UWB has emerged as the leading technology for applications like wireless Binary Serial Bus USB. UWB radios, like generic OFDM radios, require wide signal bandwidths and multiple carriers, but UWB designs also require short-duration pulses and transmit Power Spectral Densities PSDs near the thermal noise floor which can make creating UWB test signals binary difficult. Fortunately, the AWG Series and RFXpress offer a solid solution for the generation of UWB test signals. The AWG and RFXpress have the capability to digitally synthesize and generate signals in the UWB spectrum. For either custom UWB signal or ones defined for the latest WiMedia specification, the AWG solution can recreate signals that are binary to band hop in real time over a GHz modulation bandwidth. The RFXpress software signal users complete control binary the characteristics of their UWB signals including the preamble synchronization sequences, cover sequences, and TFCs. Serial signals are made up entirely of simple ones and zeros - binary data. Historically engineers have used data generators to create binary signals. As clock rates have increased these simple ones and zeros have begun to look more like analog waveforms because embedded in the digital data are analog events. The zero rise time and the perfectly flat tops of textbook digital signals no longer represent reality. Electronic environments have noise, jitter, crosstalk, distributed reactances, power supply variations, and other shortcomings. Each takes its toll on the signal. A real-world digital "square wave" rarely resembles its theoretical counterpart. Since the AWG Series is an analog waveform source it is the perfect single-box solution generator is used to create digital data streams and mimic the analog imperfections that occur in real-world environments. The AWG 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 AWG Series instruments. This is exactly what is needed for rigorous receiver testing requirements. The transmission environments of both board and cables can be emulated using touchstone files uploaded into SerialXpress. 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.
