R_DWELL: Resonance Dwell Resonance is detected by measuring the phase difference between the control point and the response signal from a resonant part of the item under test. The test frequency is controller to maintain resonance as the structure fatigues.
After holding at the resonance for a pre-defined duration, sweeping can be resumed, until the next resonance is detected.
A_DWELL: Amplitude Dwell A transmissibility plot is taken from two points on the structure under test and resonances listed.
A sine test can then be run at each resonant frequency, with tracking of the resonance by either amplitude or phase.
LIMIT CONTROL Response channels can be specified as limit control channels. If the level on a limit control channel would exceed its limit, the test level is reduced accordingly.
Multi Sweep Sine A traditional wide-band sine sweep is divided into several narrower-band sine sweeps, which when added together combine to cover the original wide band. Running the narrow band sweeps in parallel significantly reduces the test time required.

SOR: Sine on Random Random vibration and sine vibration frequencies are combined. Sine vibration can be swept.
ROR: Random on Random Broad-band random combined with sweeping or non-sweeping narrow-band random overlaid.
Extended ROR The extended ROR makes it possible to operate an ROR test with greater freedom when defining separate NBR references.
PSD LIMIT: PSD limit control Response channels can be specified as limit control channels. If the PSD on a limit control channel would exceed its limit, the test level is reduced over that range of frequencies to keep with the limit level.
Non-Gaussian A vibration testing method which precisely reproduces non-Gaussian vibration, such as transportation vibrations with large spikes.
Soft-Clipping A clipping function that can reduce the peak value of the output voltage without affecting control performance.

LONG WAVEFORM The length of a reference waveform is 16K points as standard. This can be increased to 200 K points by adding the LONG WAVEFORM option. At a sampling frequency of 512Hz for example , this produces approximately 6.5 minutes of waveform, compared to the standard length of approximately 30 seconds.
MEGAPOINT A further increase in waveform duration can be obtained by adding the MEGAPOINT option to the LONG WAVEFORM option. This increases the record length to 5000K points, about 163 minutes at 512-Hz sampling rate.
SRS: Shock Response Spectrum SRS (Shock Response Spectrum) can execute the test in which the test condition and evaluation are conducted not based on waveform itself, but on SRS analysis.
With standard shock test selected, SRS analysis of response waveform is also possible.
