EDM Modal SIMO FRF Testing includes a dedicated test setup
and operation process flow using a single shaker to acquire
FRF signals. Using a large channel count data acquisition
system (i.e., Spider- 80X or Spider-80Xi), this shaker excitation
method provides much higher test execution efficiency for the
FRF measurements.
The output type supports pure random (white noise), burst
random, Chirp/Burst Chirp, pseudo random, and periodic
random. For pseudo random and periodical random types,
delay block and cyclic block numbers can be set bringing the
structure to periodic response prior to data acquisition and
cyclic average. This results in leakage-free measurements and
requires no window function.
