Versatile Laboratory Aid
The Versatile Laboratory Aid (VELA) is a 4-channel Data logger, data logging tool that was created as part of a joint venture by Ashley Clarke, Keith Jones and David Binney of Leeds University and Educational Electronics. The VELA was designed to be used as a stand-alone data logger that could be used out in the field and it could then be taken back to the laboratory where it could be connected to a chart printer, oscilloscope or microcomputer for data analysis purposes. The VELA was designed and built with the intention that it would be used in schools and Universities to monitor Physics and Chemistry experiments as it could be attached to all manner or analogue probes and sensors such as pH meters, Thermometer, temperature sensors, light gates, Signal generator and microphones. Each of the VELA's four channels can be independently set to record voltages in the ranges of +/–250mV, +/–2.5V and +/–25V allowing a range of different input devices to be connected simultaneously. ...

Signal Generator
A signal generator is one of a class of Electronics, electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well. There are many different types of signal generators with different purposes and applications and at varying levels of expense. These types include function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators, and frequency generators. In general, no device is suitable for all possible applications. A signal generator may be as simple as an oscillator with calibrated frequency and amplitude. More general-purpose signal generators allow control of all the characteristics of a signal. Modern general-purpose signal generato ...

IBM-PC Compatible
An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. "Wintel" is a similar description that is more commonly used for modern computers. The designation "PC", as used in much of personal computer history, has not meant "personal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
