Abstract :
WITH THE advancing application of sinusoidal analysis to servo systems, the need has arisen for instruments that will measure a-c steady-state quantities in the frequency range of usual servo operation, either by use of conventional portable instruments or by the development of new instruments. At the present time the oscillograph and oscilloscope are the most commonly used tools in the analysis of servo systems. If the indicating instrument could be used, it would eliminate analysis of oscillograms.
