AVT976 A

The logic analyzer is one of the basic devices in the electronics studio dealing with digital technology. Its operation is relatively simple - just sample the digital input signals and store them in RAM. Then you have to present them in a transparent way.
Presented waveform imaging device uses a graphic LCD display and works without having to be connected to a computer. The system was designed based on two ATmega microcontrollers. One of them deals with display operation, the other one is responsible for collecting digital signals. Thanks to this solution, it is possible to study waveforms with sampling frequencies higher than the clock speed of the processors.

The device is especially recommended for people and laboratories dealing with digital technology
