20/40 MHz Logic Analyser

With analogue electronics, an oscilloscope is usually sufficient for solving any problems encountered during development or troubleshooting. With digital electronics, things are not so simple. It is often necessary to observe several different logic levels at the same time, and on top of that, high working frequencies are quite common. A logic analyser is clearly the proper tool in such a situation.A normal oscilloscope is not particularly suitable for working with circuits containing microprocessors, DSPs or other digital components. The bandwidth is usually too small for the extremely fast signals used with such components. Furthermore, it is usually not possible to view more than two signals at once (in the best case, four signals can be viewed). Also, an analogue oscilloscope can only measure repetitive signals, which is not very helpful with digital signal streams.
