1Hz-50MHz oscillator frequency meter measuring frequency measurement

Translation missing: zh-CN.products.product.overview 1Hz-50MHz oscillator frequency meter measuring frequency measurement Five-digit LED display DIY kit


Description
This is based on PIC microcontroller frequency, plus or minus the frequency with crystal measurement function and programmable settings,
five digital display, easy and intuitive, all using in-line components, the circuit is simple, easy to make.
Circuit characteristics:
Measurable frequency range of 1 Hz -50 MHz (1Hz-50MHz);
The most commonly used to measure the oscillation frequency of the crystal oscillator;
Five-digit precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz);
Automatic range switching, without human handover;
Programmable subtraction frequency setting, such as a transceiver for measuring equipment;
Selectable power-saving mode, if within 15 seconds no significant change in the frequency automatically turn off the display;
You can use a common USB 5V interface, power supply, can also use an external DC power supply or 9V battery.
A small number of elements, all in-line components, installation is simple.
PCB Size: 80 * 53 mm
A single set of weight: 0.034KG


You can also directly input frequency signals between the IN and G (ground) were measured,
note the measured signal amplitude not higher than 5V to avoid damaging the IC.
Decimal point flashes to indicate whether the unit of measure,
when the test frequency value is KHZ decimal point flashes
when the test frequency is MHZ decimal point is not blinking.
Plus or minus a certain frequency can be set through the programming mode,
the program built four frequencies 455kHz, 4.1943MHz, 4.4336MHz, 10.700MHz can be directly used settings.
Specific use programming mode please request product specification,
All line components, PCB printing press to the correct welding,
after welding is completed with a standard source input signal,
adjust the yellow adjustable capacitor so that the display is equal to the value of the signal frequency.
Our signal generator can be used to adjust, without the standard signal, you can use the direct calibration accuracy better crystal.
Power can use USB to 3.5 mm power cord, you can also - direct input 5-9V DC power supply and + pad place.

Features:
100% Brand New and High Quality

Note: Purchase Notes:
1. Product title marked "DIY kit" are parts, need your own welding assembly, to demonstrate the convenience,
the main products of the physical map Pictured welding is completed,
the second figure is all the parts that you receive,
be sure to pay attention distinction;
2. The  kit production needs appropriate electronic technology and ability,
make sure you can complete the production!
We offer a suite of high-quality components and all are done by real,
will provide the product after giving electronic version of the installation instructions with detailed pictures and comments,
and provide technical advice, try to help you solve the problems in the installation,
but the element and PCB can not be returned after the cut foot tin,
does not accept the result of the installation is unsuccessful and request a return or negative feedback!
