Model WX1284C

1.25GS/s Four Channel Arbitrary Waveform Generator

The WX1284C is a 1.25GS/s four channel arbitrary waveform generators, which offer unrivaled performance, in unmatched case size and cost, without compromising bandwidth and signal integrity. Using the very same 12.5” width, 2U height box as the single and dual channel versions of the WX series, the four channel additions provide more channel density for high-speed AWG than ever revealed before in a benchtop, allowing customers to shrink, even further, their bench or system space.

Universal Waveform Source

Aside from its natural ability to generate arbitrary shapes with waveform granularity of 1 point, the WX series can also be used as a full-featured standard, modulation or pulse/ pattern generator to solve various applications. Equipped with up to 1.25GS/s, 14-bit DAC and up to 32Mpoints memory, the WX1284C can generate literally any waveform, short or long, at frequencies up to 500MHz with 12 digits of resolution, resulting in the highest precision signal creation and regeneration without compromising signal fidelity or system integrity.

Signal Integrity and Purity

One of the most important requirements in today’s testing and measurement applications is high signal quality. With a typical SSB phase noise of <-115dBc at 100MHz, and <-105dBc at 500MHz, at 10 kHz carrier offset and with exceptionally good SFDR of <-60dBc at 500MHz carrier, Tabor’s WX1284C unique platform delivers one of the best quality signals available on the market today, answering the ever-growing demand for clear and precise signals.

Common or Separate Clocks

The new four channel architecture offers two SCLK sources, enabling users to choose between a common or separate SCLK feed. A common SCLK source allows for all outputs to be fully synchronized with 10ps of skew control for accurate and controlled phase between channels, ideal for many X-Y modes, I&Q output and even 4 channel MIMO link applications. Alternatively, users can select to work with two separate SCLK sources resulting in two separate channel couples (1&2 and 3&4) with each having the ability to be programmed to output different function shapes, frequency, amplitude levels and/or to operate in different run modes, in effect having two separate dual channel instruments in one box.

DC or HV Output Amplifiers

Have a requirement for different output paths in your lab? Great! The new four channels additions to the WX series offer two single or differential ended DC coupled output amplifiers: 2Vp-p into 50Ω with 700MHz bandwidth, for applications demanding optimized transitions and aberrations or 4Vp-p into 50Ω with 350MHz bandwidth, for applications demanding high voltage.

Powerful Segmentation and Sequencing

Solving almost every complex application, powerful segmentation and sequencing produces 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, jump and nest, saving you precious memory space. The WX series also allows you to generate up to 1000 sequence scenarios and sequence between them to generate an even higher level of flexibility in waveform creation.

Dynamic Segment / Sequence Control

Working in the real-time world and need fast waveform switching? The WX series has a rear panel control designed specifically for that. Having the dynamic control feature, in effect, can serve as replacement of the sequence table where the real-time application can decide when and for how long a waveform will be generated. For much more complex applications, this same input may serve as a dynamic switch for complete sequences, creating real-life scenarios for real-time applications.

Smart Trigger

Until now, you've been forced to trigger on a specific event. Tabor's all-new SmarTrigger feature was designed to enhance the trigger capability and facilitate wider flexibility of a specific pulse event. It allows triggering on either a pulse having a larger pulse width than a programmed time value (time), or even on a pulse having a pulse width between two limits (<>time). In addition, the SmarTrigger has a hold-off function, in which the output is held idle after the first trigger and starts a waveform cycle only with the first valid trigger after a hold-off interval has lapsed, allowing you to solve endless «negotiation» scenarios.

Pulse / Pattern Creation

Generating complex pulse trains has never been easier. The Pulse Composer is a powerful built-in tool that converts the WX series to a very sophisticated Pulse/Pattern Generator, allowing to create literally any complex pulse train / pattern, whether it’s a single pulse, multi-level, linear-points, initialization or preamble pattern definition, user-defined or even standard random patterns with programmable resolution, so it doesn’t matter if your application is radar communications, nanotechnology or serial bus testing, the pulse/pattern composer is the right tool for your application. Moreover, all the WX series’ advanced trigger modes are applicable, hence one can choose to use the “step” mode to advance every bit independently or the “once” mode to advance a complete data block in one trigger event, enabling even more applications, such as trigger, clock and data protocols.

Programmable Markers

The WX1284C is equipped with one programmable differential marker for each output channel. Differential simply means outstanding signal integrity for high frequencies, whereas the programmability allows you to set position, width, delay and amplitude for any required peripheral triggering need. While bench usage enables setting only one marker position, you can set multiple markers and program different marker properties for each transition instance remotely, allowing various triggering profiles.

Digital Outputs (Option D)

In today’s world, many applications require multiple digital outputs or a parallel digital interpretation of the analog outputs. With the new digital option the WX now offers 32 programmable digital outputs, up to extra 16M of digital memory, up to 1.15Gb/s of data rate and controllable skew between outputs. Combined with Tabor’s dedicated digital signal amplifier, WXD1, the WX is, by far, the best mixed signal source on the market to meet all of today's requirements.

8-Channel Capability

Need more than four channels to drive your application? With two 4-Channel WX units you can reach 8 synchronized channels system using a Master-Slave arrangement, allowing users to benefit from the same high quality performance even for multi-channel needs.

Easy to Use

Large and user-friendly 4” backlit color LCD display facilitates browsing through menus, updating parameters and displaying detailed and critical information for your waveform output. Combined with numeric keypad, ten quick-link function & run mode buttons, cursor position control and a dial, the front panel controls simplify the often complex operation of an arbitrary waveform generator.

Multiple Environments to Write Your Code

The WX series 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.
