Multichannel acoustic and vibration analyzer
FFT analyzers

The OROS series multi-function FFT analyzer is PC-based, high-performance, reliable, and easy to operate.

We have further increased the arithmetic processing speed and real-time analysis capacity to more than 16 times that of conventional models. An Ethernet LAN interface is used for high-speed connectivity.

In addition, the number of simultaneous recording channels in the frequency range (40 kHz) has been expanded to a maximum of 1000 channels, and the dynamic range has been improved to 140 dB. These improvements allow users to measure time signals over a wide frequency range simultaneously on multiple channels.

Introducing the Hardware

OROS noise and vibration analyzer instrument

Small and Lightweight

  • **OR10-8ch**: 0.8kg
  • **O4-4ch**: 0.5kg
  • **OR35 TW-10ch**: 3.0kg
  • **OR36 TW-16ch**: 5.2kg
  • **OR38 TW-32ch**: 8.2kg

Ethernet LAN Interface

Achieves high-speed communication with a PC through a reliable Ethernet LAN interface.

Built-in Battery

OR10, OR35, TW OR36, and TW OR38 models include a built-in battery:

  • **OR10**: up to 4 hours
  • **OR35**: up to 3 hours
  • **TW OR36 / OR38**: up to 2 hours
  • **O4**: powered by the PC battery

External Battery

External battery on spectrum analyzer

A compact and lightweight external battery is available for all models, providing up to 8 hours of autonomy. It can be conveniently stored in the "PC integrated carrying case."

Synchronous Measurement (Up to 1000 Channels)

(TW OR35 / OR36 / OR38 only)

High-precision synchronous measurements (0.2° @ 20kHz) are achieved by daisy-chaining analyzers with standard LAN cables. This setup is ideal for large-scale modal analysis or complex tracking measurements.

Cascade mode setup

Sound, Vibration, Strain, and Temperature

(OR35 / OR36 / OR38 only)

Temperature and strain conditioner

By adding a strain gauge or thermocouple conditioner, the OROS FFT analyzer becomes a complete multi-physics acquisition system.

CAN-bus Module

Can-bus module for OROS instrument

(OR10 / TW OR35 / OR36 / OR38 only) The CAN-bus module allows for tracking analysis using engine speed (RPM) or other parameters directly from the vehicle's bus, eliminating the need for external tachometers.

Standalone Recording (D-Rec)

(OR35 / OR36 / OR38 only)

Vibration time signal measurement without PC

The D-Rec feature allows for recording signals without a PC. Simply select a predefined setup and use the physical record button on the instrument.

The hardware is also equipped with audio terminals and power supplies for proximity probes, tachometers, and DC sensors.
