Seamless transition from simulation to generation

If a waveform can be defined or captured, then the AWG70000A can generate the signal. The creation of the waveform can happen in many ways. Waveform creation plug-ins, which are optimized to work specifically the Tektronix AWG family, provide specific waveform creation capabilities, while 3rd party solutions like MATLAB, Excel, or others, have the flexibility to create any waveform you desire. Waveforms created in any of these packages can be imported and played back in the AWG70000A, seamlessly transitioning from the simulation world to the real world.

Additionally, any signals captured on Tektronix oscilloscopes or Real-Time Spectrum analyzers can be loaded into the AWG70000A and played back. With the use of the built in waveform generation plug-ins, the captured signal can also be modified or changed to meet any specific requirements that may exist.

Wideband RF signal generation

RF signals are becoming more and more complex, making it more difficult to accurately create the signals required for the testing and characterization of RF systems. To address these challenges, RF Generic delivers advanced capabilities to synthesize digitally modulated baseband, IF and RF/microwave signals supporting a wide range of modulation schemes.

The RF Generic, Radar, Multitone, OFDM, and Environment plug-in’s easy to use graphical user interfaces integrate seamlessly with the AWG70000A Series user interface or the SourceXpress remote PC application.

The AWG70000A with the RF Generic Plugin allows complex RF Waveform Generation

The latest digital RF technologies often exceed the capabilities of other test instruments because of the need to generate the wide-bandwidth and fast-changing signals that are increasingly seen in many RF applications such as Radar, RF communications, OFDM, and Multi-tone. When used in conjunction with the specific plugin, the AWG70000A Series supports a wide range of modulation formats and simplifies the task of creating complex RF waveforms. The AWG70000A Series instruments provide customers with ways to generate fully modulated baseband, intermediate frequency (IF) signals, or directly generated RF waveforms up to 20 GHz.

Radar signal creation

Generating advanced radar signals often demands exceptional performance from an AWG in terms of sample rate, dynamic range, and memory. The Tektronix AWG70000A Series sets a new industry standard for advanced radar signal generation, by delivering wide modulation bandwidths up to 20 GHz. With a sample rate of up to 50 GS/s the AWG70000A Series can directly generate RF signals never before possible from an AWG. In instances where IQ generation is desired, the AWG70000A offers the ability to oversample the signal, thereby improving signal quality with its outstanding SFDR performance.

The AWG700000A and the Radar plug-in are the perfect solution for creating complex radar signals. Users get 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 of the plug-in enables the creation of waveforms requiring customer-defined modulation. The combination AWG and Radar plug-in solution also has the ability to generate pulse trains with staggered PRI to resolve range and doppler ambiguity, frequency hopping for Electronic Counter-Counter Measures (ECCM), and pulse-to-pulse amplitude variation to simulate Swerling target models including antenna scan patterns, clutter, and multipath effects.

Environment signal generation

The mission-critical nature of many radar signals requires that they coexist with standards-based commercial signals sharing the same spectrum without performance degradation. To meet this expectation, a radar designer has to thoroughly test all the corner cases at the design/debug stage. The AWG70000A and the Environment plug-in offers extreme flexibility to define and create these worst-case scenarios.

You can specify up to 50 scenarios to define your environment, including WiMAX, WiFi, GSM, CDMA, W-CDMA, DVB-T, Noise, Bluetooth, LTE, OFDM, Radar and more. This plug-in also allows you to seamlessly import signals from other plug-ins (including Radar, RF Generic etc.), as well as from Matlab® and from Tektronix spectrum analyzers and oscilloscopes, into your environment. You can also configure PHY parameters of your standard-specific signals. You can define the carrier frequency, power, start time, and duration for all the signals in your environment, so you have full control over the way these signals interact/interfere with each other.

Coherent optical

Today's high speed and increasingly web driven world is pushing the demand for short and long haul coherent optical development. Phase modulation, high baud rate, high sample rate, bandwidth and resolution are all critical to optical applications. Tektronix understands the challenges and inconsistencies of coherent optical testing and offers a reliable, easy to set up and high performing tool set for optical testing, waveform generation and calibration.

The Tektronix AWG70000A Series Arbitrary Waveform Generator (AWG) can reach sampling rates as high as 50 GSa/s with 10 bits vertical resolution. Such level of performance allows for the direct generation of IQ basebands signals required by modern coherent optical communication systems based on quadrature modulation of an optical carrier with data rates well over 200Gb/s. Multiple AWG70000As can be synchronized (manually or with the AWG Synchronization Hub) to use the max 50 Ga/s on each baseband signal with low EVM and 32 Gbaud performance.

Generating the desired signal is only the first challenge in coherent optical. The quality of the signal, low EVM's and having a clear open eye is crucial. The Optical plug-in, in conjunction with the pre-compensation plug-in, can be used for calibration of the AWG to the device under test and for precompensation of coherent optical signals.

Generic OFDM creation

In today's wireless world, OFDM is becoming the modulation method of choice for transmitting large amounts of digital data over short and medium distances. The need for wide bandwidths and multiple carriers create challenges for engineers who need to create OFDM signals to test their RF receivers. The AWG70000A Series, when coupled with the OFDM plug-in, allows users to configure every part of the OFDM signal definition. Engineers can build signals symbol-by-symbol to create a complete OFDM frame or let the plug-in choose default values for some signal aspects. The combined AWG and OFDM plug-in supports a variety of data coding formats that include Reed Solomon, Convolution, and Scrambling. Users also have the ability to define each subcarrier in the symbol which can be configured independently for type, modulation, and base data. The OFDM plug-in gives visibility into all aspects of the OFDM signal by providing a symbol table that gives a summary of all the carriers in the selected symbol. OFDM packets/ frames can be built by specifying the spacing between the symbols/frames and parts of the OFDM packets can be stressed by adding gated noise.

High-speed serial signal generation

Serial signals are made up entirely of binary data- simple ones and zeros. As clock rates have increased, these simple ones and zeros have begun to look more like analog waveforms because analog events are embedded in the digital data. 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 AWG70000A 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 AWG70000A Series uses direct synthesis techniques to allow engineers to create signals that simulate the effects of propagation through a transmission line. Rise times, pulse shapes, delays, and aberrations can all be controlled with the AWG70000A Series instruments. When used in conjunction with the High Speed Serial (HSS) plug-in, engineers are provided control over every aspect of their digital signals reaching speeds of up to 50 Gb/s. This is exactly what is needed for rigorous receiver testing requirements.

Easily create digital data impairments with the AWG70000A and HSS plug-in.

The HSS plug-in allows the AWG70000A 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 S-parameter files that can be applied to any waveform. The AWG70000A and the HSS plugin 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 AWG70000A 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.
