This is a frequency meter based on PIC single chip microcomputer, with crystal oscillator measurement function and programmable addition and subtraction frequency setting, five digit nixie tube display, convenient and intuitive, all use in-line components, simple circuit and easy to make.
Circuit features:
Measurable frequency range: 1hz-50mhz (1hz-50mhz);
It can measure the oscillation frequency of most common crystal oscillators;
Five bit precision resolution (e.g. 0.0050 kHz, 4.5765 MHz, 11.059 MHz);
Automatic range conversion without manual switching;
Programmable addition and subtraction frequency settings are used to measure equipment such as radio transceivers;
Power saving mode can be selected. If there is no obvious change in frequency within 15 seconds, the display will be automatically turned off;
The universal USB 5V interface can be used for power supply, and external DC power supply or 9V battery can also be used.
The number of components is small, all in-line components, and the installation and commissioning are simple.
PCB size: 80 * 53mm
Single set weight: 0.034kg
