徴とする第１項記載の周波数測定アダプタ。[Claims for Utility Model Registration] (1) An input terminal, a voltage divider that receives a frequency measured signal from the input terminal and creates a low voltage that has a constant relationship with the signal voltage, and a voltage divider between the voltage divider and a subsequent device. There is an impedance converter with appropriate impedance in its front and rear devices, a comparator that inputs the output of the impedance converter and creates a rectangular wave from the input waveform, and a comparator that inputs the output of the comparator and creates a rectangular wave from the input waveform. A frequency measurement adapter comprising: a frequency divider that creates a signal by dividing the frequency of the signal into an integer; and an output terminal that outputs the signal. (2) The frequency measurement adapter according to item 1, further comprising a power source consisting of a battery, a load for checking the power supply voltage, and a switch connected to the output terminal for switching on and checking the power.
