AT2040 Portable
Vibration Calibrator
The AT-2040 Gen-2 Portable Vibration Calibrator provides multiple test modes for real-world vibration calibration, sensor verification, and analyzer validation. Each mode supports different workflows — from direct shaker excitation to sensor simulation and bearing fault reproduction — enabling comprehensive testing in the field or lab.
Four operating modes — one complete verification workflow
Each mode supports a specific step in sensor testing, system validation, and reliability training.
Vibration Output
Establish and verify true mechanical motion using the built-in electrodynamic shaker while continuously measuring actual vibration output.
Live feedback includes sensor sensitivity, bias voltage, mass loading, and distortion — providing confidence before automated testing.
Bearing Defect
Generate realistic bearing fault signatures — including inner race, outer race, and rolling element defects — to validate analyzers, support training, or demonstrate diagnostic techniques without running machinery.
Sensor Test
Perform automated, multi-point sensitivity testing with configurable frequency and amplitude sweeps.
Live graphing and onboard data storage allow technicians to validate sensor performance quickly and repeatably.
Sensor Simulation
Simulate the electrical output of vibration sensors without physical motion, acting as a vibration-specific signal generator.
Validate cabling, inputs, and monitoring systems independent of sensor mounting or machine operation.
Together, these modes allow technicians to verify sensors, validate systems, and build confidence in vibration data — from initial setup through advanced diagnostics.
Vibration Output
Vibration Output mode is used for manual vibration testing with real-time measurement of actual shaker output. Rather than assuming vibration levels based on drive settings, the AT-2040 continuously measures true mechanical motion using its internal reference sensor.
In this mode, the user manually sets vibration frequency and amplitude while the system provides live feedback on measured vibration level, sensor sensitivity, displacement, harmonic distortion, and amplifier load. This closed-loop approach allows users to confidently verify sensor performance and system response under real mechanical excitation.
Vibration Output mode is particularly useful for manual verification, troubleshooting, and exploratory testing, where direct control and immediate feedback are required before transitioning to automated test routines.

Bearing Fault Simulation & Verification
The AT-2040 Gen 2 includes an integrated bearing fault pulse generator that produces realistic, repeatable bearing defect waveforms for condition monitoring system validation, alarm testing, and technician training.
Fault simulation capabilities
- Inner race, outer race, ball, and cage defect simulation
- Adjustable defect frequency and repetition rate
- Stable, repeatable pulse generation
- No damaged bearings or rotating machinery required
When to use this mode
This mode is used when validating bearing fault detection logic, alarm thresholds, and analysis techniques, rather than overall vibration level accuracy.
Why This Matters
Bearing Fault Waveform Behavior
The oscilloscope captures shown below illustrate the waveform characteristics produced by the AT-2040 Gen 2 bearing fault simulation.
Automatic Sensor & Proximity Probe Testing
Fully automated vibration and proximity verification — no manual setup, no spreadsheets, no PC software.
The AT-2040 automatically controls frequency and amplitude, measures sensor response in real time, and calculates sensitivity across defined test points — all directly on the instrument.
The Sensor Test mode automates vibration sensor calibration by controlling output levels, measuring response, and calculating sensitivity across defined test points.
This mode reduces setup time and eliminates manual calculations, providing consistent, repeatable results suitable for both field verification and laboratory use.
- Automatic frequency and amplitude control
- Live sensitivity, bias, and deviation measurement
- Repeatable test points with no user input
- Cert-ready results for calibration documentation
- Designed for both field and laboratory workflows
Not limited to accelerometers
The same automatic test framework also supports proximity probe dynamic testing, including controlled amplitude sweeps and sensitivity verification — using the same on-device workflow with no external software.
