Frequency Counter 2.5 GHz (to buildt yourself)

   Frequency range 5 MHz to 2.5GHz
   High sensitivity input typ 15mV at 150MHz
   Two level of resolutions, 1kHz and 100Hz
   On-board oscillator 13MHz or external 5 MHz
   Counter data can be displayed on PC via com port (RS232)
   Add or subtract 3 different IF frequencies : (±455 kHz ,±10.7 MHz and ±21.4 MHz)
   +7.5 to 35 VDC input power supply
   Low current consumption typ 35 mA

What you are buying are the  three most important components of a 2.5 GHz Frequency Counter Kit

3 Components are the Pre Programmed Microcontroller (PIC16F870) and the PLL Synth (LMX2322)  and the 5 Mhz external oscillator module (temperature compensated with external PPM adjust- will supply detail to buyer)

Other components should be readily available in South Africa
