1Hz-50MHz DIY Kit Digital LED Kristal Oscillator Frequency Counter Meter Tester

Color: Red

SIze: 8 x 5.4cm

Suitable For:

Crystal measure (4M, 16M crystal)

Crystal measure (20M, 11.0592M crystal)

Features:

This is a PIC microcontroller-based frequency meter, subtraction frequency is set with

crystal measurement functions and programmable, five digital display, easy and intuitive,

all using in-line components, the circuit is simple and easy 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;

3. Five-digit precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz);

4. Automatic range conversion, without human handover;

5. Programmable subtraction frequency setting, such as a transceiver for measuring equipment;

6. selectable power saving mode within 15 seconds if there is no significant change in the frequency automatically turn off the display;

7. You can use a common USB 5V interface, power supply, can also use an external DC power supply or 9V battery.

8. A small number of elements, all in-line components, installation is simple.

Instruction manual

1. All line elements, PCB printing press to the correct welding,

2. After welding is completed with a standard source input signal,

3. Adjust the yellow adjustable capacitor so that the display is equal to the value of the signal frequency
