アス電源として１２０〜１３０Ｖの電源を加えている。The transmitters of the DME and Takan devices use klystrons as electron tubes that generate high power. This klystron has a plate voltage of 11-13KV.
A high voltage of 120 to 130 V is applied to the cand, and a bias power supply of 120 to 130 V is applied between the cand, grid, and rad.

がある。As mentioned above, in order to measure the voltage of a conventional bias power supply, it is necessary to take large-scale insulation measures using high voltage, and since it is not possible to directly measure the superimposed bias power supply, it is difficult to measure the voltage using a partial voltage that includes high voltage. The disadvantage is that measurement accuracy cannot be obtained.

In the figure, the bias power supply voltage is divided into voltages within a measurement range by a light emitting diode 6 and a constant voltage diode 8 connected to the bias power supply. The light emitting diode 6 is an element whose intensity of emitted light changes depending on the applied voltage, has insulation against high voltage, and outputs an analog signal a generated by optical coupling to the differential amplifier 10. The light emitting diode 7rt connected to the −1 reference voltage 9 has the same standard as the light emitting diode 6 described above, and outputs an analog signal corresponding to the reference voltage to the differential amplifier 10. Differential amplifier IO uses analog signals a and b
It compares and outputs the difference to the correction circuit 11, and also has the effect of canceling out drifts caused by the surrounding conditions.
