Signal Generator

AT-2040 Signal Generator Feature.


AT-2040 features a built in signal generator capable of producing high accuracy electrical signals over a wide frequency and amplitude range. Designed specifically to simulate accelerometer output, the AT-2040 portable vibration calibrator features the ability to simulate current, voltage, and charge signals that precisely mimic a variety of transducers and sensors. The AT-2040 is capable of reproducing multiple wave shapes with precision, making it the ideal portable vibration calibrator for detecting faults within cabling, connectors, and data equipment.


Signal output types: Voltage charge and 4-20ma outputs:

  • Charge signal mode for simulating accelerometers and other piezoelectric sensors.
  • Voltage signal mode for simulating voltage generating sensors.
  • 4-20ma adjustable current for simulating 4-20ma sensors (also known as a 4-20ma loop simulator.)


  • Cabling and wiring troubleshooting
  • Vibration signal simulation – accelerometers and velocity probes
  • Machinery speed signal simulation
  • Calibration of:
    • Accelerometers
    • Proximity Probes and Drivers
    • Monitoring systems
    • Charge amplifiers
    • Avionics equipment

NOTE: This Feature is NOT Available on AT-2030.
