• Color: Red SIze: eight x 5 Suitable For: Crystal measure (4M, 16M crystal) Crystal measure (20M, 11 crystal) Features This is a PIC microcontroller-based frequency meter, subtraction frequency is set with crystal measurement functions and programmable, 5 digital display, easy and intuitive, all using in-line components, the circuit is easy and straightforward to make 1 measurable frequency range of 1 Hz -50 MHz (1Hz-50MHz); 2 The most commonly used measure of the oscillation frequency of the crystal; three Five-digit precision decision (eg zero kHz, four MHz, 11 MHz); four Automatic differ conversion, without human handover; 5 Programmable subtraction frequency setting, corresponding to a transceiver for measuring equipment; 6 selectable energy saving mode inside 15 seconds if there isn't any meaningful replace in the frequency routinely flip off the display; 7 You can use a standard USB 5V interface, strength supply, can also use an exterior DC strength supply or 9V battery 8 A small number of elements, all in-line components, set up is simple Instruction handbook 1 All line elements, PCB printing press to the correct welding, 2 After welding is completed with a typical supply input signal, three Adjust the yellow adjustable capacitor in order that the show is equivalent to the value of the signal frequency Packing Included 1 x 1Hz-50MHz frequency meter (DIY kits, no longer assembled)
