The Application of Direct-Current Resonant-Line-Type Pulsers to the Measurement of Vacuum-Tube Static Characteristics

In order to utilize a power tube efficiently, the static characteristics of this tube must be known. From these characteristics, optimum load lines may be determined and circuit components of the equipment may be defined. The problem of obtaining these characteristics is usually not a simple one, due to the power-input limitations put upon a tube. For this reason, characteristic curves were previously plotted by capacitor-discharge methods or were calculated mathematically, using low power points as references. This paper describes a method of obtaining this information, employing pulse circuits commonly used in radar transmitters.
