Precision Waveform Generation is Key for Industrial Control and More

Sophisticated ADwin Control System Generates Any Waveform You Need

A signal generator is an device that produces analog or digital signals in either repeating or terminating modes.  The aim of signal generation is to produce signals that conform as closely as possible to a desired shape using frequency, phase, and offsets to fine tune the system.  CAS Data Loggers offers ADwin Real-Time Data Acquisition and Control systems for many common automation applications where specific waveforms shapes are required.

Practical applications for precision waveform generation include control of lasers, electron beams and high-voltage pulsers most often used in research environments.  Signal generation is also used in R&D for simulation of sensors and dynamic excitation for determining system characteristics for troubleshooting.  As a side note, there are also artistic applications for audible tone generation for music making.

ADwin High Performance Real-Time Control

16_waveform_examplesFrequency, phase and offset can be smoothly adjusted online, often in a single step. Users can also generate arbitrary waveforms by the superposition of various base signals.

The numerically-generated waveforms can either be output directly or used internally as set-point values for digital closed-loop or open-loop controllers running simultaneously on the same ADwin system. Additionally, input signals can be acquired and evaluated at the same time for monitoring limit values.

Additionally, users can set up complex controls by using the ADwin system’s capability of synchronously outputting multiple analog and digital signals on a time- or event-triggered base.

When an ADwin system is used as a signal generator it falls under the adaptive signal generator category.  This means you can define each signal’s properties by adjusting set points and how the system responds to measured values.  Any waveform is possible and it doesn’t matter what your application is ADwin can control it!

Real-Time for Complex Applications

The ADwin data exchange with a PC is fully compatible to work with the interfaces for VB, Matlab, etc.  Users save considerable time by reusing valuable ADbasic source code after just a few changes to the tried and tested algorithms.  The new Pro-II system provides extraordinary speed that enables demanding applications at high data rates.  In addition, the fast T-11 processor allows an intelligent process to pre-determine  relevant data, mathematical functions, or digital channel filtering.

All new Pro-II modules automatically sync when run in the Pro II chassis which allows fully-synchronized time measurements from multiple modules without any special software to program.  The ADwin ADSP processors enable complex calculation, for example it processes up to 50 ADbasic lines in just 1 ms!  The T11 processor also has extremely short response times so your control or regulatory processes can run reliably on the with cycle frequencies far above 1 MHz.
