PLJ-0802 intelligent frequency meter is a frequency measuring instrument
specially designed for embedded applications. It's small, simple and reliable.
Mainly used for DIY transceivers to display frequency value, and can also be used
for conventional frequency measurement.
Main features of this frequency meter are as follows:
Ø Microchip PIC16F648A forms the core of the 2.4GHz frequency meter.
Ø Frequency reference using a temperature-compensated voltage controlled
crystal oscillator (2.5 ppm VC-TCXO).
Ø Dual mode IF modes allow the offset value and the IF up / down mode to be
separately preset.
Ø Using LCD0802 liquid crystal display, it can display up to 7 digits, and the zero
is automatically blanked.
Ø Reverse power protected connection design, low power consumption battery
power supply scheme.
Ø 2 Button Control
Ø Setting is automatically saved in EEPROM, and it will be recalled directly at
next startup.
