SIRIUS® signal conditioning technology

Data acquisition systems are built around our world-class SIRIUS® signal conditioning technology and offer the same top-performing technologies:

  • DualCoreADC® technology: high-dynamic range and signal-to-noise ratio (SNR).

  • SuperCounter® technology: high-speed synchronized angle and speed measurement.

  • Galvanic isolation: channel-to-channel and channel-to-ground isolation for best signal quality and safety.

Note: galvanic isolation does not apply to SIRIUS mini and MINITAURs instruments.

Available signal amplifiers

SIRIUS® data acquisition systems offer different signal conditioning amplifiers grouped into three main amplifier families.

DualCoreADC® amplifiers

High dynamic range inputs (160dB)

These amplifiers feature dual 24-bit Delta-sigma ADC. 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.

Each channel is capable of acquiring the input signal at a 200 kS/s sampling rate.

High-density (HD) amplifiers

Same Speed. More Channels. Optimized Price. 

High-density (HD) amplifiers are built with the same dual 24-bit Delta-sigma ADC with an anti-aliasing filter and 200 kS/s sampling rate per channel. The main difference to DualCoreADC® amplifiers is that HD amplifiers use each of the two Delta-sigma ADCs as separate input and thus double the number of input channels while still keeping great signal-to-noise and dynamic range specs.

SIRIUS high-density signal conditioning cards thus offer double the input channels (16 analog channels) in the same chassis enclosure. These modules offer the best price-per-channel-to-performance ratio.

High-speed (HS) amplifiers

16-bit SAR ADC with high-speed sampling

SIRIUS® high-speed (HS) amplifiers are equipped with 16-bit SAR ADC. They offer high bandwidth and acquisition rates of up to 1 MS/s sample rate per channel. These amplifiers are suitable for recording fast transients and for applications where a high sampling rate is a must (such as power analysis).

The SIRIUS® modules with high-speed (HS) signal conditioning amplifiers are available in 8 analog input channel configurations.

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.

Channel-to-channel galvanic isolation

SIRIUS DAQ devices offer high galvanic channel-to-channel and channel-to-ground isolation (±1000 V). The DAQ systems even offer isolated sensor excitation.

With such isolation, we have no problem measuring high voltage potentials and no problem with common-mode voltages. We are also safe with measurements like vibrations, temperatures, or any other measurement where non-isolated sensors are placed next to the high voltage potential against the DAQ system ground. In such cases, a non-isolated DAQ system would burn or at least give faulty wrong results. With SIRIUS it is just one thing less to worry about.

Digital isolation has another big advantage - preserving the frequency bandwidth of the amplifiers. SIRIUS provides "worry-free" measurements, less noise, no ground loops, and the best possible signal quality.

For less demanding measurement and lower-cost applications, SIRIUS DAQs are also available in a differential version where only power supply isolation is offered.

SuperCounters®: precise speed and angle measurement with counter and encoder sensors

Dewesoft data acquisition systems utilize a patented and registered trademark technology called SuperCounter®.

Counter inputs can measure the RPM and angle of rotating machines. In comparison to standard counters, which only output integer numbers one sample later (e.g. 1, 1, 2, 2, 3, 4), the Dewesoft SuperCounter inputs are able to extract accurate values like 1.37, 1.87, 2.37, etc. fully synchronized for time and amplitude.

This is done by measuring the exact time of the rising edge of the signal with an additional counter. Our SuperCounter inputs work on a 102.4 MHz time base, independent of the current analog sampling rate.

Counter inputs are fully synchronized with analog, CAN bus, and other data sources to enable easy applications like balancing, order tracking, and torsional vibrations.

External calibration reference

SIRIUS® R8 systems feature optional calibration reference input. External calibration reference can be connected via a single BNC connector on the rear side of the system. It can be switched in the software to all input channels at once to check the amplifier performance and accuracy.

Please note: check your local sales office for information on which SIRIUS® amplifiers have the support for external cal reference.

Analog Out

SIRIUS® R8 system can be configured with up to 64 analog output channels. These output channels can function in any of the following modes:

  • stand-alone digital signal amplifier,

  • multi-channel function generator for modal/shaker control,

  • control channels or

  • a replay of the analog data.

To learn more visit the SIRIUS DAQ system page for a detailed description of individual modes. 

For the real-time low-latency output and control capability we offer SIRIUS R8rt data acquisition and control system. R8rt is a unique solution on the market. It has an additional real-time EtherCAT bus and can feed data to any 3rd party EtherCAT master controller for real-time control. Please visit the SIRIUS RT page to learn more.

Analog Output Modes

The analog outputs on SIRIUS can be configured and used with one of the following modes of operation.

Function Generator

The DewesoftX software offers a multi-channel function generator. Together with the SIRIUS analog out hardware options it can generate and output signals like sine, triangle, rectangle, saw, or even an arbitrary table. The generated signal can be continuous or in a sweep, step sweep, burst, and other modes. A lot of fine-tuning can be done in the function generator during the measurement in real-time.

Function generator on SIRIUS can be an excellent way to excite vibration shakers​​​​​​​ or any other device requiring simple analog input signals.

Standalone Signal Conditioning

With this mode, you can use the SIRIUS data acquisition systems as a pure, standalone signal conditioner. No DewesoftX software or USB connection to a PC is required. Any physical input signal is converted directly to an analog output voltage signal of max. ±10 V.


  • Any analog input is possible

  • Signal conditioning: scaling, offset, gain

  • Redundant DAQ system: simple mathematic functions

  • Standalone operation possible

Control Channels

DewesoftX software features control channels that allow any SIRIUS data acquisition device with analog output to directly access its analog outputs and manually assign a value in real-time during the measurement. 

The control channels mode can be used for controlling peripheral hardware with actions like Start, Stop, Pause, Freeze, Store, Trigger, Screen event, Keyboard even, and many more. Choose out of many different instruments like vertical and horizontal slider bar, turning knob, buttons, edit box, etc.

File Replay to Analog

When your measurement data is recorded you can replay your data file and output the conditioned channels on the SIRIUS analog out channels. This feature is useful for post-processing and analysis or to feed the data to a 3rd party testbed and simulate e.g. the vibrations during a test drive. Please note that this is not a 0 latency output.

For real-time data feed to a 3rd party EtherCAT master controller SIRIUS DAQ systems also offer Dual Mode capability. Dual-mode gives the ability to feed data to a 3rd party controller in real-time with very low latency. This is enabled through all SIRIUS devices with EtherCAT port.

Real-time, low-latency data output

We offer an "RT" (real-time) version of SIRIUS® data acquisition systems. These systems include a secondary EtherCAT® data bus on the back side of the instrument. This data bus can be used to output reduced rate data in parallel in real-time to any 3rd party EtherCAT® masters.

The real-time EtherCAT® bus is available on the following SIRIUS systems:

  • SIRIUS® modular EtherCAT®

  • SIRIUS® R2, R2-HUB

  • SIRIUS® R4, R4-HUB

  • SIRIUS® R8

Lovedby Many Engineers

I wanted to personally write to you and tell you how impressed I am with Dewesoft products. The whole Dewesoft team impressed me as extremely happy, smart, and dedicated.

The combination of software, hardware, and the Polygon plugin is really great. And on top of that, we can use it for so many things. This is just what we have been looking for!

It has been a long day, but before going home I wanted to say few things. Thank you from the bottom of my engineer heart and in the name of OneSubsea for what you did today! Yesterday at 10 PM I sent you an email asking for urgent help on a Saturday morning. 30 minutes later you replied you would come. This morning you were 5 people involved in resolving the issue. I have never experienced such customer service! Thanks again, customer service matters a lot to us, and today's response blew me away.

I think I mentioned in previous emails how Dewesoft has mushroomed here, but even I didn't know how much. I was informed today that the data was being reviewed by up 50 to 60 different centers, along with NASA personnel as high as the manager of the entire Space Shuttle program.
