  • Short duration pulses are required for the testing of computer switching and wide-band devices.

    The TF1389 employs the coaxial line discharge process to provide pulses with a risetime of less than 500 psec. A coaxially mounted mercury wetted relay contact is driven by a sinusoidal signal at up to 350 c/s, discharging a length of coaxial cable and forming the pulse. The pulse width is determined by the length of cable used, and provision is made for pulse lengths of 2·5, 5, 25, 50 and 100 nsec;
    different length pulses are obtainable are obtainable by using external cables. 600 W of peak pulse power is given. Wireless World, July 1962, Page 316.
