LeCroy’s LW400B Series WaveStation“ is a dual-channel, 400 MS/s arbitrary waveform generator (AWG) that combines high-performance with the flexibility and capability needed to quickly generate long, complex waveforms. The LW410B offers the same performance characteristics in a single channel unit. The WaveStation offers more than just great technical specifications. It provides a high level of functionality and ease of use while eliminating many of the traditional obstacles of AWGs.
LeCroy’s WaveStation combines innovative signal processing, high-performance design, and human factors engineering to provide a truly intuitive and highly interactive arbitrary waveform generator.

The Choice is Yours

Specify the waveform and let the LW420B handle the details, or take control yourself.
With the WaveStation, you don’t need to know the sample clock period or the particular reconstruction filter being used. All the LW420B needs is your waveform’s time and voltage relationships. No matter which of the many available tools you use to specify the waveform, the LW420B will generate the output using the optimum combination of sample clock rate and filter bandwidth. The automatically selected filters will ensure that aliasing is avoided and that all the timing relationships within the waveform are precisely maintained. Full control of the clock and bandwidth filter also exists for those who need it.

Control Waveshapes Easily and Interactively

Real-time waveform manipulation lets you quickly control the waveshape -- easily and interactively --while viewing it on the built-in CRT display.
Select a section of the waveform using the time cursors, then select one of a set of waveform manipulation operations (e.g., move feature, delay, amplitude) and turn the knob. That’s how easy it is to continuously modify all or part of a waveform. Time shifts as small as 100 ps, amplitude variations on a peak, or changes in signal duration are instantly reflected in the output signal. Margin testing or characterization, even of the most complex waveforms, has never been so easy.

Waveform Creation Has Never Been Easier

You can select application-specific waveform libraries of traditional functions, or create waveforms using equations, or import them from external sources such as oscilloscopes, computer programs, and simulator output files. After waveforms are created or captured, they can be further modified using internal waveform (array) math processing. The waveform math functions include basic arithmetic operations, smoothing, integration, differentiation, and convolution.

The highly developed waveform editing capability uses advanced signal processing to provide bandlimited cut/paste/insert, and offset operations with minimal editing artifacts. Single-sample resolution, which further simplifies waveform creation, is possible because waveforms are not constrained to eight sample multiples as with most other AWGs.

To simulate real-world signals, the internal, asynchronous, wide-band noise generator is easily used to add controlled amounts of noise to your signals. Simply dial in the noise level as a percentage of your signal’s amplitude. And here’s a real timesaver: if you vary the signal’s amplitude, the signal-to-noise ratio is maintained.

Flexible Waveform Import and Transfer

Pull waveforms directly from most digital scopes, then connect a GPIB cable between the LW420B and your digital oscilloscope. You’re ready to begin importing waveforms.

Waveforms of up to 1 Mpoint in ASCII format or from programs such as Mathcad, MATLAB, PSPICE, IQSIM, TOPSIM, and others can be imported from the floppy drive. You also can use a shareware program offered by LeCroy to convert your files to DIF format and transfer them directly to the LW420B over GPIB.

When importing or transferring files, you have the choice of oversampling or importing the points exactly as they are. Then the WaveStation’s modification, editing, and math tools can be used to put the waveform in the shape you need for your task.


Fast Switch Group Sequence

LeCroy’s Fast Switch Group Sequence capability lets you switch between many different preloaded waveforms in less than 11 ms. Waveforms continually play until a sequence advance is received from the front panel or a remote command. Choose to auto advance from sequence to sequence, or choose to jump to the n’th sequence in a group. Generate a continuous output of a sequence selected from the group, or use the external trigger input to initiate a burst or single shot of the selected sequence.

Digital Output Option

The digital output option provides 8-bit TTL and ECL digital outputs corresponding to the current value of the CH 1 analog output. The latched digital data is held for the duration of the sample clock. The digital data, including the sample clock and its complement, are available via rear-panel connectors. A special digital editing mode is useful for creating and editing byte-wide data patterns or selected bits, and the standard “cut-and-paste” tools are available for analog waveforms.

Generate Complex Stimuli

A maximum sample rate of 400 MS/s, up to 1 Mbyte of waveform memory, a precise timebase, and single-point resolution give you the power to generate the most demanding, complex stimuli. The timebase’s 3 ppm accuracy and 1 ppm/year stability ensure the waveforms you use to test your systems next year will be the same as the ones you use today. Low single-sideband phase noise and a 1 Hz frequency resolution over a continuous 6 kHz to 400 MHz range provide the flexibility and capability needed to generate even the most complex and demanding waveforms.

Fully Integrated AWG

With its high-speed 486 processor; internal hard disk drive; built-in nine-inch, monochrome VGA display; and 24 Mbytes of RAM, WaveStation provides all the power needed to work with long and complex waveforms. The LW420B is a fast, responsive instrument, ideally suited for the interactive graphical operations required in a high-performance AWG.
