    Can any one suggest me any circuit for displaying RF frequency at around 3GHz? This RF is produced using DRO and input to the display circuit is provided after dividing the signal frequency by 4 (F/4 module). i.e. 3GHZ/4 == 750MHZ is to be read by the display circuit. And provisions be made to multiply it again to 3GHz. Precision for displaying 3GHz is upto 7 digitby using 8 seven segment displays.

    So, can any one suggest me any circuit for displaying frequency using 8No. seven segment displays in this fashion ===> 88888.888 MHZ (ie."03000.000" MHz)

    Thanx :)

  2. I don't know much about high speed stuff... like what's the fastest counterone can buy. But you could just divide your input (by say 100) so 30MHz. and then count for one second.

  3. 2,6 Ghz enough?

    This is a divide by 1000.

    For a 8 digit counter just add another display sections.
