Analog & Digital Waveform Generator, 50MSa/s, ELMII Series

The Analog & Digital Waveform Generator ETC M631 is a hardware and software package that turns your PC into a powerful, dual channel generator. It connects to a PC via a parallel port or to a USB port with an optional USB-to-parallel-port adapter.

Waveform Generator Key Features

Two independent output channels
Two modulation inputs
One external trigger input/trigger output
Update rate up to 50MSa/s
Voltage output levels from 160mVpp to 16Vpp
Voltage shift from -4V to +4V
Powerful waveform editors
Import from ASCII (e.g. Mathlab)
Import of waveforms from M621 digital storage scope
Generation of 16-bit digital words
Software for Win 9x, ME, NT, 2000, XP

Both analog signals and digital events can be defined using up to 256K points. The resolution of a voltage waveform is 8 bit, The width of a digital word is 16 bit. Digital event generation requires the optional A631 digital adapter, which is not contained in the basic package.

The included M631 control software allows an easy access to all the waveform generator functions by mouse. Predefined functions allow easy generation of standard waveforms, such as sinus, saw, triangle, rectangular and noise.

Several powerful waveform editors allow you to custom define virtually any desired waveform.

Digital patterns can be generated using the digital wave editor (pattern generator).
A mathematical editor allows you to express a waveform as a mathematical function. Supported expressions are addition, subtraction, multiplication, division, absolute value, sin, cos, square and percentage.
With the manual graphical editor you can simply draw a signal waveform.
The harmonic editor synthesizes a signal from up to 256 harmonic components.
The amplitude modulation editor, finally, enables you to create a harmonic wave of a given frequency that is modulated by a chosen wave.

It is possible to set the signal waveform, level and magnitude of a superimposed voltage (one-directional shift) for each channel independently.

The generator's output voltage amplitude can be modulated by applying an external signal through the external modulation inputs

Channel B frequency can be defined as an integer multiple of the channel A frequency. In addition a phase shift between the output voltages of channel A and B can be set.
