Enter frequency/amplitude breakpoints in an easy to read table form. Operator can select to control constant or ramped acceleration, velocity, or displacement. Automatically calculate and enter the frequency of intersection between any combination of constant acceleration, velocity, or displacement lines. Over 1000 separate frequency/amplitude breakpoints can be entered, allowing entry of virtually any test spec.

Either linear (Hz/minute or minutes/sweep) or logarithmic (octave/minute, decade/minute, minutes/sweep) sweeps can be specified. Sweep rate can be changed in the test while running.

Test duration can be entered in terms of length of time, number of sine wave cycles, or number of sweeps.

Sequences of fixed-frequency tones of a specified acceleration, velocity, or displacement can be run. Looping functions allow easy entry of repeating tone sequences.

The control signal can be a single input channel, or configured from 2 to 32 input channels with either multi-channel averaging or (optional) multi-channel extremal control.

Transmissibility peaks can be automatically detected from a sine sweep, and then dwell tests run at the detected resonance frequencies for a specified time duration or number of sine wave cycles. In a sine dwell test, the controller can automatically track the resonance frequency to keep the output on resonance even when fatigue damage causes the resonance frequency to shift.

The controller can be configured to abort if the controlled acceleration goes above or below the desired level by an operator-configured number of dB. Abort limits can also be enabled for individual monitoring channels. Drive limits can be configured to protect from overdriving your shaker in case of failed accelerometers.

Input channels have individually selectable tracking filters to remove harmonics and out-of-band noise from the measurements. The tracking filter bandwidth and signal averaging is user configurable.

All of the test data can be stored to the disk for later retrieval. Data storage can be done manually, or programmed to automatically save at user-defined intervals.

Stepped frequency sine tests such as those used in MIL-STD-167 are supported. The on and off duration and the step size are programmable.

Provides an easy interface to calculate accelerometer sensitivity. This will allow the user to perform a sine sweep, controlling on a reference accelerometer, and produce a calibration report suitable for calibration record keeping. Automatically calculates the accelerometer sensitivity at the chosen frequency.

Allows more than one input channel for control in a control strategy where the highest, lowest or an average of accelerometer readings will be used for control of the test

A configurable large numeric readout displays the current test frequency and channel amplitudes.

The frequency sweep and amplitude level can be manually controlled through the mouse.

The second output channel supplies a 1-volt constant amplitude reference signal. The phase of this signal relative to the main output can be fixed at any phase or set to shift at a configurable rate. This signal may be used to trigger a strobe light or other measurement device requiring triggering lock with the output signal.

A multitude of graphical display options are available, including peak acceleration, peak velocity, peak-to-peak displacement, output drive, channel-to-channel transmissibility, and phase as a function of either frequency or time. Graphs can be easily auto-scaled or zoomed, and cursors displayed. Data and text annotations can be easily placed on the graphs, with data values updated live as the data changes.

Assigns maximum limiting breakpoint profiles to individual channels. The drive output will be limited (or ´notched´) if necessary to keep the input amplitude for that channel below the defined profile. Up to 1024 breakpoints can be entered for each channel, or the limit can be entered simply as a dB level relative to the demand profile. In addition, minimum limits may be defined to boost the drive output if a channel is below a defined profile. The notching profiles may also be used as spectrum abort limits, so that abort limit breakpoint profiles can be assigned to each individual channel, and if that channel reaches the defined limit the test will safely shut down.
