Abstract :
The possibilities and restrictions for the use of the simple experimental method differential electronic gating (DEG)-developed to determine the shape of repetitive subnanosecond THz pulses in the presence of a large jitter in the trigger signal are investigated. This method, a modification of the recently reported differential optical gating method, is based on subpicosecond electronic gating employing a high frequency sequential oscilloscope. As the ultimate test, the shape of 10 ps FWHM THz pulses from the free electron laser FELIX has been measured
