Zusammenfassung:PROBLEM TO BE SOLVED: To provide a portable terminal and its frequency characteristic adjusting method, which reduces the time for adjusting frequency characteristics (variation at each frequency) of the portable terminal, having a plurality of different output frequencies. SOLUTION: The portable terminal 101 uses a spectrum analyzer 103, which is under the control of a computer (PC) 102 for adjusting its frequency characteristics. The terminal 101 comprises a CPU 105, an interface 115 for interconnecting the CPU 105 and the PC 102, a frequency controller 106, a gain controller 107, a timing generator 104, a modulator 109, a gain control amplifier 111, a local signal oscillator 110, an up-converter 112, and an external connector 114 for connecting an amplifier 113 to the spectrum analyzer 103.
