1 MHz ~ 1.2 GHz PLJ-0802-A frequency meter.

This is a listing for a frequency meter module with a range of 1MHz to 1.2GHz.

Here is a detailed specification sheet:

1 MHz ~ 1.2 GHz PLJ-0802-A frequency meter frequency measurement.

PLJ-0802 embedded intelligent frequency meter designed specifically for HAM frequency measuring instruments. Its compact, easy to operate, reliable, mainly for DIY transceiver for frequency display, can also be used in conventional frequency measurements. The main features of the frequency meter are as follows:

With Microchip's 8-bit microcontroller PIC16F648A as the core of a high-performance 1.2GHz frequency meter.

Built-frequency reference is temperature compensated voltage controlled crystal oscillator (± 2.5 ppm VC-TCXO).

Double IF design, IF value and the plus / minus mode can be preset separately.

Usins LCD0802 LCD display, can display up to seven digits, zero frequency value is invalid automatic blanking.

Anti-reverse power design, low power consumption for battery-powered solutions.

Two-button control, a good man-machine interface.

The settings are automatically saved in the EEPROM, the next boot called directly.
