fig. 1-1. A double exposure photograph of the output pulse from the Tektronix Type 110 (no external charge line) and a 1 gigacyclel sec timing train. The waveforms are displayed on a Tektronix 0.12 nsec risetime research-type oscilloscope. This photograph shows the risetime to be well under 0.25 nsec. The minimum pulse width is approximately 0.5 nsec. Note the freedom from overshoot.
