Oscillographic techniques for the evaluation of magnetic amplifier response
D.L. Critchlow · Transactions of the American Institute of Electrical Engineers Part I Communication and Electronics · 1955
A COMMON way to study the transient response of a magnetic amplifier upon application of a step of signal or to examine its frequency response to periodical signals is to use a recording oscillograph or a cathode-ray oscilloscope. If an oscilloscope is used its sweep rate can be slowed down so as to contain a whole transient in a single sweep. Repetitive switching arrangements controlling the initiation of the transient and the time sweep make the latter procedure suitable for direct visual observation of a stationary pattern.1
