The WW2074 offer a 200 MS/s four-channel universal waveform synthesizer. Each is built in a small case size to save space and cost but without compromising bandwidth and signal integrity. The instrument outputs either standard or user-defined waveforms in the range of 100µHz and up to 80MHz.

As technology is evolving and new devices are developed every day, faster signals are needed to simulate and stimulate these new devices. The four channel models provide the highest bandwidth in their class and hence provide accurate duplication and simulation of test signals. With a wide range of sample clock generators (up to 100MS/s), 16-bit vertical resolution and wide output bandwidth (up to 50MHz), one can create mathematical profiles, download the coordinates to the instrument and re-generate waveforms without compromising their fidelity and compatibility to the original design.

16-bit DAC`s are used for building waveforms with excellent accuracy and resolution which are suitable for the finest test signals that are needed for today`s sensitive instruments. Using the latest technology, you can be assured that the features and capabilities of the four channel models will be useful for many years.

The four channels models have four output channels which are all synchronized to the same reference clock and share the same sample clock. This is not a limitation because the output frequency is a function of the number of points which are used for creating the waveform shape. On the other hand, the advantage of having four synchronized channels is huge in applications that require accurate and controlled phase between channels. Many applications require XY drive so two channels is just what is needed however, for three phase power simulation and four channel MEMS micro engine actuators, the four channel model is the most suitable product to use.

Care to use the instrument as a function generator? No need to fuss with loading complex waveform coordinates, simply select the standard waveforms tab and start generating any one of the ten waveforms that are pre-computed and available for immediate use. Included are: sine, triangle, square, pulse, ramp, sinc and others.

As standard, the instrument is equipped with a frequency reference that has 1ppm accuracy and stability over a period of 1 year. An external frequency reference is provided on the rear panel for applications requiring greater accuracy and stability.

Waveform memory is the internal “black board” where the waveforms are created and reside. Large memory bank provides for longer waveforms. One can use the entire memory for a single waveform or split the length to smaller segments. In this case, many waveforms can be stored in the same memory and replayed, one-at-a-time, when recalled to the output. The memory segmentation is combined with a sequence generator that can take different memory segments and link (and loop) them in any order as required for the test. The ability to loop waveform segments in a sequence saves a lot of memory space and hence, extends the capability of the generator to produce complex and much longer waveforms, which would otherwise require large banks of memory. The four channel models have four sequence generators that can be designed to generate unique sequences for each output channel.

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.

Access speed is an increasingly important requirement for test systems. Included with each instrument is a variety of interfaces: Ethernet, USB and GPIB so one may select the most suitable interface for the application. Remote control of instrument functions, parameters and waveform download is easily tailored to specific system environment regardless if it is just a laptop to instrument or full-featured ATE system. IVI drivers and factory support will speed up system integration and hence minimize time-to-market as well as significantly reduce system development costs.

Normal 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. Leading-edge technology was implemented to allow calibration from any interface, USB, GPIB or LAN. Calibration factors are stored in a flash memory thus eliminating the need to open instrument covers.

All models come 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.

Multiple four channel models can be synchronized using a Master-Slave arrangement allowing users to benefit from the same high quality performance in their multi-channels system.

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.
