Abstract: A remote tone burst pulser for an electromagnetic acoustic transducer utilizes a circuit having a direct current power source which is provided to a main capacitor. A high power, high speed insulated gate bipolar transistor or metal oxide-semiconductor controlled thyristor is operatively connected to the main capacitor and the coil of the transducer. A drive circuit is operatively connected to this device for transmitting a train of switch pulses which causes radio frequency alternating current to be provided to the transducer coil. A power transistor is operatively connected to the first transistor and is activated by a second drive circuit for causing a conducting state which allows for the power being applied to the transducer coil to be rapidly dissipated by a resistor and the internal resistance of the power transistor.
