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)
