This reciprocal FREQUENCY COUNTER is a microprocessor-controlled instrument for frequen-
cy measurement.  Due to uniquely developed LSI circuitry in an expanding/reciprocal system,
high accuracy with 9-digit resolution is achieved with a one second gate time.  It covers a fre-
quency range of from 0.1 Hz to 3.5 GHz based on a 10 MHz TCO (Temperature Controlled
Oscillator).  Other features include:

Also provided is a self-test function for a quick check of several operating modes. Each mode

can be selected by a front panel push button switch with automatic decimal points and indica-
tors. The high accuracy, sensitivity and versatility of this counter make it an extremely valuable
instrument to the scientist, engineer, experimenter and communications technician. Lightweight
and compact size make it practical for use by the hobbyist or field technician.
