Abstract

PURPOSE:To make analysis receiving and sound receiving possible simultaneously by sweeping a frequency synthesizer for local oscillation in time division and performing the sampling in the IF output synchronously with this sweep. CONSTITUTION:Frequency synthesizer 22 has the oscillated frequency sweep-controlled during a tuning mode period and a weep mode period in time division, and the oscillated frequency is made fixed during the tuning mode period and is changed in steps during the sweep mode period. The output converts the input signal to an IF signal in 11, and the tuning mode detection output is supplied to speaker 17, and the sweep mode detection output is supplied to spectrum display device 21.
