1.2GS/s Performance

As products, which use increased signal bandwidths evolve, test equipment and systems must keep pace with this trend. The WW1281A with its high sample rate generator assures that this test tool does not lag the outbreak of new technology. Combined with unsurpassed price tag, the WW1281A is the logical choice for future test technologies.

16M Memory

The WW1281A offers 8M words of waveform memory and 16M word as an option for generating extremely long arbitrary waveforms. In addition, the memory can be divided into as many as 16k segments, which can be looped and linked in many different ways. Harnessing such memory to the high speed performance of the WW1281A provides breakthrough solution for many applications.

Powerful Segmentation and Sequencing

Solving almost every complex application, powerful segmentation and sequencing produce a nearly endless variety of complex waveforms. The waveform memory can be divided into multiple waveform segments and sequenced in user-selectable fashion to create complex waveforms that have repeatable segments and thus saving precious memory space. Five different advance modes are available for the WW1281A to step through the sequence table, including stepped and mixed advance modes and thus increasing efficiency of the test system. In addition, a rear panel connector has 8-bit control of segment replay providing additional and extremely useful hardware tool to hop between segments.

Frequency Agility

Decrypting radio transmission often employs frequency hopping. The WW1281A provides breakthrough technology that allows simulation of 2-level decrypted code as easy as simply writing two frequencies. The frequency hop mode is fast, coherent and provides a great tool for simulating code transmission without loosing speed and/or integrity.

Accurate Output

As standard, the instrument is equipped with an internal frequency reference that has 1ppm accuracy and stability over a period of 1 year. A rear-panel input for an external frequency reference is available for applications requiring greater accuracy or stability. Using the external reference input and an external controlling host computer will enhance frequency setting resolution to an amazing 9 digits of resolution.

Modulation Capability

Agility and modulation capabilities open the way for limitless array of applications. Not only can the WW1281A generate any shape and style of waveforms, but modulations such as FM, FSK, PSK, and Sweep are easily employed without sacrificing the power of the instrument control and output run modes.

High Speed Function Generator

The WW1281A generates 10 standard waveforms such as sine, square and triangle waves. Sine and square waves can be generated at frequencies up to 400MHz, making the WW1281A one of the fastest function generators available today. The internal reference oscillator provides 1 ppm accuracy and has excellent long-term stability. An external frequency reference can be used if greater accuracy or stability is required.

Two Serial Digital Output Bits

Standard with the WW1281A are two digital outputs, placed on the rear panel and supporting applications that require simultaneous generation of analog waveforms and digital streams. The instrument’s sample clock generator drives both front and rear outputs and therefore provides jitter-free simulation of analog signals combined with serial data streams. The serial data is generated from the digital outputs at baud rates up to 2.4GHz.

Automated External Self-Calibration

Usually, calibration cycles in the industry range from one to three years where instruments are sent to a service center, opened to allow access to trimmers, calibrated and certified for repeated usage. In contrast, the innovative advanced technology implemented in these systems allows calibration from any interface, USB, GPIB or LAN. Calibration factors are stored in a flash memory and thus eliminating the need to open instrument covers.

Easy to use

Large and user-friendly 3.8” back-lit color LCD display facilitates browsing through menus, updating parameters and displaying detailed and critical information for your waveform output. Combined with numeric keypad, cursor position control and a dial, the front panel controls simplify the often complex operation of an arbitrary waveform generator.

High Speed Access

Access speed is an increasingly important requirement for test systems. Included with the instrument is a variety of interfaces: LAN, USB and GPIB so one may select the interface most compatible to individual requirements. Using any of the external interfaces, controlling instrument functions and features as well as downloading waveforms and sequences is fast, time saving and easily tailored to every system regardless if it is just a laptop to instrument or full-featured ATE system. IVI drivers and factory support will speed up system integration thus minimizing time-to-market and reduce system development costs significantly.

Multiple Environments to Write Your Code

Model WW1281A comes with a complete set of drivers, allowing you to write your application in various environments such as: Labview, CVI, C++, VB and MATLAB. You may also link the supplied dll to other Windows based API’s or, use low level SCPI commands (Standard Commands for Programmable Instruments) to program the instrument, regardless if your application is written for Windows, Linux or Macintosh operating systems.

Two-Instrument Synchronization

Two WW1281As can be synchronized using a Master-Slave arrangement allowing users to benefit from the same high quality performance for their multi-channel needs. This arrangement can convert two WW1281As into a two-channel system that is phase-coupled for applications such as I & Q and more.

ArbConnection

The ArbConnection software provides you with full control of instrument functions, modes and features. ArbConnection is a powerful editorial tool that allows you to easily design any type of waveform. Whether it is the built in wave, pulse or serial data composers, or the built in equation editor with which you can create your own exotic functions, with ArbConnection virtually any application is possible.
