AVT389 A

The logic analyzer is for the designers of digital circuits the basic measuring instrument. The prices of factory equipment are very high, the solution is to make the analyzer by yourself.
The system has a nice and functional interface for a PC. The analyzer allows you to register up to 32768 samples. The recording can be triggered in three ways: manually, automatically CMP (any combination of states on inputs) and automatically EDGE (any edge). The main element of the system is memory 62256 cooperating with the ATMega 8515-16 processor. Communication with the computer is provided by the serial port.

The device is especially recommended for lovers of digital technology, in the service of microprocessor systems and construction studio
