Take Advantage of the Wonder Wave Series Capabilities To make the most of Tabor`s AWG, test engineers need the signal creation and edition tools that perform without exposure to complex signals and instrumentation. Wireless communication, with its ongoing evolution, emerging standards, increasing bandwidth and complexity requirements is an area where traditional generators must often be replaced or upgraded to keep pace with application needs. Arbitrary Waveform Generators, on the other hand, are limited only by their resolution, sampling speed, record length and intrinsic linearity. With devices reaching or exceeding 16-bit resolution, 1 GS/s and 75dB SFDR, multi-carrier, channel coded, high quality signals can be generated easily.

Ideal Tool for Various Signal Environments MODULAR provides the wireless engineer with the ideal tool to easily define, analyze and transfer such signals to the target AWG. In fact, MODULAR provides all the essentials to use any AWG in a specific signal environment: Baseband: 2 or more channel AWGs support I and Q baseband      signal generation. These signals can be used directly or as an input      for an external I-Q modulator. IF: Intermediate frequency signals can be used directly or as an input      to an external up-converter. RF: Modern AWGs with sampling frequencies beyond 1 GS/s allow      direct generation of multiple carriers right at the required carrier      frequency. Mixed signal environments are not a problem as AWGs support digital generation easing the integration of DSP based software-radio architectures.

Signal Quality that Meets Your Expectations Measurements of the distortion introduced by any DUT are dependent on the stimulus signal applied to them. Using MODULAR, engineers control the quality necessary to meet the expectations required by each application. Users can make trade-offs between compilation speed and ACLR, between time-domain (EVM) and frequency domain (ACLR), or simply make the most of the available hardware. Continuous signal generation requires seamless signal repetition. Modern AWGs provide seamless looping and sequencing but error--free signal generation requires continuity at all levels: sample, carrier, symbol, baseband filtering, and, in some cases, channel coding. MODULAR meets all these requirements by automatically adjusting the carrier and modulation parameters and performing continuous signal convolution to eliminate any wrap-around effects in all the component signals. The result is a clean signal without any degradation in any frequency, time, or modulation domain parameter, no matter how many carriers or modulation schemes (analog, QAM, FSK/MSK) involved. Furthermore, MODULAR supports seamless sequencing of dissimilar (different payload) signal fragments, enabling generation of pseudo-random signal sequences with real traffic spectral density behavior allowing performance of nearly impossible measurements such as residual carrier. High quality signals with multiple channels/carriers require an additional feature - uncorrelated payloads. MODULAR allows complete definition of pseudo-random binary sequences (PRBS) for payloads, controlling both the generation polynomial and the seed values in a carrier-by-carrier basis. Additionally, carrier phase can be defined by the user or at random. This feature sharply reduces the PAPR (Peak to Average Power Ratio), hence improving linearity, dynamic range and SNR.

End-to-End Modulation Scheme Support MODULAR incorporates a complete range of modulation schemes supports including: BPSK, QPSK, O-QPSK, pi/4-DQPSK, 8PSK, O-8PSK (EDGE) QAM-16, QAM-32, QAM-64, QAM-128, QAM-256, QAM-512,       QAM-1024 8-VSB, 16-VSB 2-FSK, 4-FSK, 8-FSK, 16-FSK, 32-FSK, MSK (including GMSK) Sinusoidal Analog: AM, FM, PM User-defined modulations schemes, data, baseband filters, and data

Channel Coding and Channelization Channel coding and channelization are important features for 2G, 2.5G and 3G mobile telephony, wireless LAN and digital TV testing. MODULAR offers channel-coded signals for the following environments: DVB-C: QAM-64, QAM-256. Scrambling, interleaving, Reed-Solomon      and differential coding supported. CDMA IS95 (CDMAOne) Downlink: Spreading, channelization (Walsh      codes), complex scrambling supported. WCDMA IMT2000 (UMTS) Downlink: Spreading factor, complex      scrambling codes, channelization (OVSF codes), CCPCH-SCH      multiplexing. IEEE-802.11b: DSS spreading, Barker sequences, CCK modulation.

Analyze and Compare To be precise, MODULAR lets you analyze and compare mathematical, predictable nature of signals generated by AWGs makes them ideal for degradation analysis. MODULAR incorporates an array of analysis tools and features that can be used as references that can be compared with results generated by measurement instruments such as oscilloscopes, spectrum analyzers, or vectorial analyzers. These are some of the analysis functions available: Spectrum display: Spectral analysis allows validation of the signals in      the frequency domain Phase/Constellation diagrams Signal Density/Histogram display: It creates a gray-scale display      including histogram analysis in both the I and Q axis Eye Diagram for both I and Q components I and Q vs time displays CCDF Additionally, MODULAR can export signals in a variety of formats readable by spreadsheet applications such as Excel, or scientific/mathematical packages such as Matlab for further analysis, manipulation, and/or documentation.

Open environment with virtually endless possibilities MODULAR is an open environment. Users can choose from built-in signal parameters or define their own. Signals characteristics such as baseband filtering and payload data can be imported from externally defined files. Users can even create their own modulation schemes by editing their constellation diagrams and symbol mapping. Non-supported modulation schemes can be also accommodated through the external I-Q symbol/envelope feature.

Margin Testing Margin testing requires more than ideal signals. Impairments, noise and interfering signals must be added in order to obtain the required results. MODULAR, with its built-in impairment tool, featuring carrier feed-through and quadrature error and imbalance and multi-carrier capability, makes it possible to do all this with just a single unit.

Non-linear Impairments Non-linear impairments such as amplifier distortion (AM/AM, AM/PM distortion) are also supported. Non-linear support also helps implementing and experimenting pre-distortion correction for high-power amplifiers. Multipath emulation is as easy as filling a form with the description of the different paths by entering the delay/amplitude/phase for each delay. Testing equalizers and rake receivers has never been so easy.
