The SC-121 Sine Servo Controller provides an economical solution
to modern sinusoidal vibration testing with a remarkably convenient
operator interface and dual microprocessor design. Crystal controlled
digital signal synthesis and filtering insures performance found
only in the best controllers available.
Selectable one or two channel acceleration feedback enables control of large head
shakers, slip plates or large fixtures by averaging signals from
two strategically placed accelerometers. The difference output makes
transfer function determination and calibration tests as easy as
running a simple sine test.
Flexible programming allows internal storage of up to three independent
1, 2, 3, or 4 level test profiles. Stored test profiles are easy
to modify or replace. Digitally generated analog outputs facilitate
plotting or recording test profiles. |
