1. PRODUCT DESCRIPTION 

                   

1-1. Introduction 

                   
This reciprocal UNIVERSAL (FREQUENCY) COUNTER series are microprocessor 
controlled instrument for frequency measurement at high resolution within a short 
period of 7 digit display with one second gate time due to uniquely developed LSI as 
well as the expanding/reciprocal system. It covers a frequency range from 0.1Hz to 
3.7 GHz (FC-8300: 3.7GHz, FC-8030/8030U: 3.0GHz, FC-8150,8150U: 1.5GHz) 
based on 10MHz time base T.C.O (temperature controlled oscillator) and also 
featuring,

  A self-test mode is also provided for a quick check of several facets of operation. 
Each operating mode can be selected by front panel push button switches with 
automatic decimal points and indicators. The high accuracy, sensitivity and 
versatility of this counter make it an extremely valuable instrument to the scientist, 
engineer, experimenter and communications technician. Light weight and compact 
size make it practical for use by the hobbyist or field technicians.
