Abstract: PURPOSE:To improve frequency flatness by adding a filter provided with the same frequency characteristic as that of a path, which causes the leak of a high frequency signal, and inputting the output and an original output to a high input impedance differential amplifier. CONSTITUTION:In the case of observation while selecting the attenuation factor of an input signal to (1/10), the state of switching means 2, 4 and 6 is selected so as to connect a contact (b).

Filed: 1989-03-24
Abstract: PURPOSE:To generate a transmission pulse of prescribed voltage even when the frequency of a control signal exceeds the set max. frequency by generating a trigger signal at frequency lower than the prescribed max. frequency when control signal input is higher than said prescribed max. frequency. CONSTITUTION:A transmission pulse generating circuit 5 has a capacitor charging high voltage power therein and discharges the charge of the capacitor charged corresponding to a trigger pulse to generate a transmission pulse and outputs said transmission pulse from an output terminal 7 to apply the same to a probe. When a change-over circuit 4 is changed over to an external trigger to be brought to a state receiving an external control signal, even when the external clock received from an external control apparatus such as a computer by a clock control circuit 1 is a nonstandard clock pulse higher than the max. frequency set to the circuit 5, since the frequency of the trigger pulse is lower than the max. frequency, the transmission pulse generated from the circuit 5 can be generated at frequency equal to or less than the max. frequency. Therefore, the transmission pulse actually applied to the probe becomes a prescribed high voltage pulse.
