Abstract

PURPOSE: To carry out the test operation correctly and rationally by supplying a frequency-to-time test program, computing the amplitude and phase value output under continuous frequency condition from discontinuous frequency spots set initially, and applying the program to the vibrator.
CONSTITUTION: A frequency fN instructed from an external signal controlling part 10 is oscillated from a sweep frequency oscillator 11, and applied to a control part 14, where the frequency in a memory initially set is called. The amplitude values or phase valves of two, great and small, frequencies at the both sides of frequency fN are interpolated linearly, and the amplitude and phase corresponding to the frequency fN are computed at the control part 14. As a result, the computed value is supplied as output to a phase variable circuit 12 and an amplitude variable circuit 13, and an output of predetermined amplitude and phase are applied to the vibrator.
