DBS 2050A
2.4 GS/s Dual-Channel Arbitrary Waveform Generator
C Size VXI Instrument Module
Introduction
Building on thirty years of success developing state-of-the-art measurement solutions, Analogic introduces the most advanced broadband stimulus instrumentation available today. Engineers and scientists who rely on ultra-high-performance arbitrary waveform generators can anticipate significant performance improvements from the new DBS 2050A. Finally, an arbitrary waveform generator (AWG) possesses the power and flexibility to provide the right signals for your applications. Dramatically improve the quality of performance characterization testing on all kinds of electronic devices Generate arbitrary waveforms, including Pulse Pattern and Sinusoidal stimulus, over a frequency range of DC to 1.2 GHz with 8 bits of vertical resolution and over 60 dB of programmable gain and offset Synchronize dual outputs with a maximum time skew of ±100 ps Produce rise/fall times of 400 ps Play back waveforms with sample rate jitter of less than 10 ps RMS Increase memory efficiency by over 100 times over conventional AWG designs by using the flexible waveform and sequence memory architecture Use waveform independent runtime parameters to change the output level and offset "on the fly" Preload up to 4096 unique waveforms in memory and seamlessly link them for playback (creating very long waveform playback periods), using Dynamic Waveform Sequencing Advance from one waveform to the next using conditional waveform repeat (loop) counts as well as internal or external trigger events. Generate precise standard waveforms: square, sine, positive and negative ramps, pulse, noise, triangle, positive and negative haversines, sin(x)/x, and DC Bring your next high-speed analog or mixed signal design to market faster while dramatically reducing errors or oversight in critical design verifications. The DBS 2050A is ideal for use on the production floor or in the laboratory.

General Description
Analog signal outputs are available in true differential or single-ended form for one channel operation and single ended when operating in dual channel mode. Output amplitudes are 1.0V peak-to-peak using the primary X1 amplifiers; 4.0V peak-to-peak using the high-level X4 amplifiers. Offsets can be set to ±3.5V with 2 mV resolution. In addition to the full bandwidth output, the DBS 2050A has three selectable low pass output filters with cutoff frequencies of 200 MHz, 20 MHz and 2 MHz. Other filter requirements are accommodated with available SMA feed-thru filter modules. The sampling clock is built around a precision phase detector capable of synchronizing to internal or external references. The sample clock rate is programmable over a range of 600 S/s to 2.4 GS/s. The external reference input can range from 2.5 MHz to 100 MHz.

Flexible Operating Modes
Each output channel has two physical ports; A and B. This h i g h l y flexible architecture facilitates fast switching between ports without external control elements. The high-level output amplifiers are capable of operation to 4.0V peak-to-peak. The low-level output amplifiers deliver 1.0V peak-to-peak waveforms with great spectral purity. Gain control has 60 dB of adjustment range.

2.0 V Differential 1.0V Single Ended (X1 Output) 4.0V Single Ended (X4 Output)
Control of the output signal path is decoupled from waveform memory so gain and offset changes can be made over a wide dynamic range without disruption of the output signal.

VXI Bus Interface
The DBS 2050A comes equipped with a fully compliant VXI Plug and Play Driver, soft front panel and application source code. The toolset supports application-specific developments in Visual C/C++ or Visual BASIC, as well as National Instruments' LabWindows/CVI and LabVIEW. Waveform creation and editing software is provided by WavesmithTM, a versatile waveform development system for Windows. This tool provides a "no programming required" work environment for rapid prototyping of user waveforms, as well as direct control of all instrument functions.
Dynamic Waveform Sequencing
The unique architecture of the DBS 2050A provides a level of flexibility and functionality not found in any other arbitrary waveform generator.
