Portable 4-Channel Sound and Vibration Analyzer SIRIUS® Mini

Small, portable, USB-powered 4-channel data collection system for sound and vibration measurement. SIRIUS mini offers an amazing 160 dB dynamic range and is the perfect portable vibration analyzer or acoustic noise measurement device


USB Powered on the Go

SIRIUS mini does not require any external power supply. It can be powered straight from the USB connection, for example, a laptop. Two USB cables are included. One for power, THE second for data transfer.

Small Form Factor

SIRIUS mini is our smallest 4-channel data acquisition system. It fits into one hand, is light, and is easily transported in a backpack. Still, in this small box, you can find the power of a giant.

IEPE and Voltage Inputs

The SIRIUS mini data acquisition system is configured with four high dynamic analog inputs for direct voltage or IEPE/ICP signals. Amplifiers are equipped with two 24-bit Sigma-Delta ADC’s with a 200 kHz sampling rate per channel. DualCoreADC® technology offers an astonishing 160 dB dynamic range.

SuperCounter® Inputs

Each counter channel input is capable of three digital inputs, one event counter, encoder, period, pulse-width, duty-cycle, and precise frequency and angle measurement using patented SuperCounter® technology.

Unmatched Price

SIRIUS mini offers a very attractive ratio between price and quality. It ships with the highest quality signal conditioning amplifiers and is bundled with award-winning data acquisition software.

DualCoreADC® signal conditioning technology

The DualCoreADC® technology solves often-faced problems with signal measurement:

  • signal input overload,
  • noise, and
  • artificial frequencies in the signal caused by aliasing.

The input signal can be higher than expected by the signal conditioner (out-of-range) and therefore clipped by the ADC. This will result in an incorrect measurement and will require you to repeat the test all over again.

DualCoreADC technology prevents these problems. Each channel amplifier has two A/D converters that measure the high and the low gain of the input signal in parallel. This results in the full possible measuring range of the sensor and prevents the signal from being clipped.

With DualCoreADC technology, SIRIUS data acquisition systems achieve more than 130 dB signal-to-noise ratio and more than 160 dB in dynamic range. This is 20x better than 24-bit DAQ systems and 20x less noise.
