AVT5106 A

The system is a complete block of logic of the digital frequency meter. The AVT964 kit can be used as an input path. The "brain" of the device is the Dallas-Maxim microcontroller. The processor has implemented a synchronous frequency measurement method. Thanks to it, it is possible to study high and low frequency waveforms with comparable duration of measurements and the same relative accuracy. The result is presented on the LED display. The device management program was written in C language with assembler elements. As a result, the device was designed with high parameters, as for amateur conditions.

The device is especially recommended in amateur electronics workshops and on the website

Selected parameters:

• displaying results - LED display, 7 significant figures
• automatic range selection
• 10-6Hz measuring step
