Pulse Length
The duration of the ultrasonic transmission pulse generated by the transducer, measured in microseconds. Shorter pulse lengths provide better resolution of closely-spaced defects and reduce dead zone thickness. Pulse length is determined by transducer damping and bandwidth. Modern equipment allows control of pulse length to optimize resolution versus penetration for specific applications.
