PLJ-0802-E Mini Portable 1MHz-1200MHz Frequency Measurement Module Embedded Intelligent Frequency Meter
Description:
- PLJ-0802-E embedded intelligent frequency meter is a frequency measurement instrument designed specifically for HAM. It is compact and exquisite, easy to operate, and reliable in operation. It is mainly used for DIY transceivers to display frequency values, and can also be used for conventional frequency measurement.
Features:
- It is a high-performance 1.2GHz frequency meter based on 8-bit microcontroller PIC16F648A for Microchip.
- The built-in frequency reference adopts a temperature compensated voltage controlled crystal oscillator (± 2.5 ppm VC-TCXO).
- Dual intermediate frequency design, intermediate frequency value and addition/subtraction mode can be pre-set separately.
- Using LCD0802 LCD screen display, it can display 7 digits, and the frequency value will automatically disappear if it is invalid or zero.
- Anti reverse power design, low-power battery power supply solution.
- Dual button control, good human-machine interface.
- All settings are automatically saved in EEPROM and can be called directly upon the next power on.
Specification:
- Gate time: 0.64s
- Measuring range: 1MHz - 1.2GHz
- Measuring accuracy: ±100Hz
- Intermediate frequency setting: The minimum adjustable step length of the intermediate frequency is 100Hz, and the intermediate frequency range is 0~999.9999MHz. It can be set to add or subtract intermediate frequency mode.
- Frequency reference: adopting VC-TCXO with a frequency stability of ±2.5ppm
- Working voltage: DC 9V - 12V
- Working current: backlight on ≤55mA
- Display bit: 8 bit digital display
- Product size: 58 x 32 x 27mm
- Module net weight: 40g
- Onboard interface:
RF input (measuring signal input): XH2.54-2P square socket
ICSP input (MCU programming interface): XH2.54-6P pin
POWER input (power supply interface): XH2.54-2P square scket
Package Included:
