Emulation Technology for Lab Engineers

IC Adapters, Test Clips, Sockets and IC Testing Accessories for QFP, BGA, PGA, PBGA, SOIC, TSOP.

Emulation Technology - VLSI SMT Interconnect

Emulation Technology Inc. (ET) develops and markets specialized solutions that close the interconnect gap between electronic design, test equipment and digital hardware designs.

Emulation Technology was founded in 1983 to produce and market time-saving very large-scale integration (VLSI) and surface mount technology (SMT) adapters and accessories for engineers involved in hardware and software product development, design and test, and electronic systems manufacturing.

The ET MicroClip

The ET MicroClip is specially designed for providing new or additional test points on Printed Circuit Boards (PCB). The engineer trying to debug an existing system will find this as an indispensable tool for probing and viewing signals on a logic analyzer, oscilloscope, meter or other instrument for almost any location on the PCB with a mounted passive device.

The Math Forum - Ask Dr. Math

One of my biggest weakness was and is Math. I did not give it much thought till much later. A Consolation was that even Einstein was not good at math, but then he had a Excellent Math Friend who helped him out with that EMC2 thing.

But dont take chances, get your number right and be a Master of Calculus and Fourier Series.

Sequences and Series of Functions Grapher

The applet plots consecutive terms of a user-defined sequence or a series of functions. Those can be, in particular, Taylor series and Fourier series. A piecewise defined limit function can also be entered and plotted.

A Tutorial on Binary Numbers

Computers understand numbers and logic, as most are digital computers. The Binary Hexadecimal System is the way the numbers or logical commands are instructed to the computer. All input devices or sensors must finally talk this language to the CPU, and all outputs and actuators must be able to understand this numbers to do their job.

A bimetallic thermostat is like a simple mechanical computer. Where the bimetal response is the sensor input, the contacts are the output to actuator and the bimetal thermal behavior is of the nature of intelligence. Similarly we have opamps which can be real-time complex analog computers. And the Living Being are like biologicals robot which have all the things - a control systems, computers, sensors and actuators, even probably a wireless network. :-)

Binary Numbers
  • Bit is 0 or 1 ... one digit ... 0 could be 0 volts and 1 five volts.
  • Nibble is four bits, 4 digits, like 0010 , in hex a nibble is 0 to F.
  • Byte is eight bits, 8 digits, like 1100 0010 , in hex 00 to FF.
  • BCD binary coded decimal is binary code for numbers 0 to 9.
