Precision Waveform Generation is Key for Electronic Stimulus & Response Testing
By: CAS DataLoggers
A signal generator is a device that produces analog or digital signals in either repeating or terminating modes. The aim of signal waveform generation is to produce signals that conform as closely as possible to the desired shape using frequency, phase, and magnitude. CAS DataLoggers offers ADwin Real-Time Data Acquisition and Control systems (https://www.dataloggerinc.com/
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 design, tuning, and troubleshooting. As a side note, there are also artistic applications for audible tone waveform generation for music making.
ADwin High-Performance Real-Time Control
Frequency, 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.
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 based on 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 Pro-II system provides extraordinary speed that enables demanding applications at high data rates. In addition, the fast T-12 processor allows an intelligent process to pre-determine relevant data, mathematical functions, or digital channel filtering.
All Pro-II modules automatically sync when running in the Pro II chassis which allows fully-synchronized time measurements from multiple modules without any special software to program. The ADwin ARM processors enable complex calculation, for example, it processes up to 50 ADbasic lines in under 1ms! The T12 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
