JAGUAR Multiple Input, Single
Output
There was a time when Analog Sine controllers
were the only way to get accurate tests.
With JAGUAR, you get true analog signal generation with a pure
signal, where harmonic output is at least 80 dB down from the
fundamental. A sine controller should include
state-of-the-art-tracking filters that deliver accurate
resonance peak G definition. Q and correct frequency are
critical to decision-making after the test and to accurate
control during excitation to avoid overtest and undertest. You
need not accept estimates of Q, frequency, and peak G delivered
by FFT based “tracking filters. ”
Accurate, safe, closed-loop Sine tests are now normal – with
JAGUAR.
Excellent filtering is achieved with the combination of 6 pole
analog Butterworth filters and specialized digital filters. The
combination gives you the assurance that extremely high
frequencies, present in your laboratory, will not masquerade
(alias) as lower frequencies, slipping into your measurement
regardless of how fast you sample. The hardware filter cutoff at
225 kHz guarantees that your data are always correct.
The world is non-linear. This knowledge must be reflected by
your control system. JAGUAR is unique in its ability to adapt to
amplitude non-linearities during Random, Sine and Shock testing.
Adaptive control enhances the safety of your test article,
safely speeds progress to full level, and assures better and
easier control of your test than was ever possible before.
