High-Speed Data Acquisition (DAQ) System SIRIUS® XHS

IRIUS XHS is a high-speed data acquisition system (15 MS/s) with the new HybridADC signal conditioning technology capable of high-bandwidth transient recording and very high-dynamic, alias-free data acquisition.

Modern data interfaces such as USB 3.0, GLAN, XCP, CAN, and OPC UA, with PTP synchronisation allow for open and flexible connectivity. SIRIUS XHS is the ultimate high-speed DAQ.


HybridADC signal conditioning technology

HybridADC offers the best of both worlds. The high-dynamic alias-free acquisition of 24-bit ADC systems with up to 1 MS/s acquisition rate. High 5MHz bandwidth of 16-bit ADCs up to 15 MS/s sampling rate. Modes are software selectable for every input channel..

15 MS/s @ 5 MHz bandwidth

SIRIUS® XHS instruments offers up to 15 MS/s sampling rate with 5 MHz bandwidth. It captures transients down to microseconds levels. The sampling rate is software selectable for every analog input channel

High dynamic alias-free acquisition

SIRIUS® XHS implements alias-free filtering which allows the acquisition of analog signals in 24-bit resolution with up to 150 dB dynamic range at 1 MS/s sampling rate.

PTP synchronisation

Even though users can select some channels to be high bandwidth and some to be alias-free, filtering is designed in such a way that all signals are perfectly time aligned with zero phase shift. Multiple devices can be synced together using the PTP synchronization method.

Modern Data Interfaces

GLAN interface allows the distribution of devices with the PTPv2 synchronization. The USB 3.0 interface is there for the fastest data transfer to the PC computer. OPC UA, CAN and XCP data interfaces allow easy integration into the 3rd party system and test benches

Open protocol support

Data is transferred to any host using the open OPC UA industry-standard protocol. In parallel the data is available over XCP or CAN protocols, allowing connection to ECU calibration software packages like ETAS INCA or Vector Canape.

High galvanic isolation

High channel-to-channel and channel-to-ground isolation up to CATII 1000V. This prevents damage to the systems from excessive voltage and avoids ground loops.

Smallest Form Factor

With the standard SIRIUS-sized chassis you can easily carry the SIRIUS XHS in your backpack along with your laptop for field measurements

The familiar data acquisition system with a completely redesigned brain

The new SIRIUS XHS looks the same on the outside, but on the inside, it is a completely new beast. Everything is new and designed from scratch to face the future of high-speed data acquisition systems:

  • New brake-through HybridADC signal conditioning technology.
  • New amplifiers that follow the capability of the new HybridADC technology.
  • A new, much more powerful FPGA with an ARM processor running onboard Linux OS.
  • Better galvanic isolation technology for channel-to-channel and channel-to-ground isolation.
  • USB3 type C and Gigabit LAN data interfaces support huge data sampling speeds.
  • PTPv2 synchronization technology.

We have been developing SIRIUS XHS high-speed data acquisition system for the last 6 years and the results are astonishing. We simply love how the technology supersedes even our expectations and lays foundations for the future of data acquisition.

HybridADC signal conditioning technology

Which ADC converter is better? SAR ADC or Delta-sigma ADC? Well, now it doesn’t matter anymore. SIRIUS XHS data acquisition systems introduce Hybrid ADC signal conditioning technology. HybridADC offers the best of both worlds. It allows users to select modesof operation for each analog input channel:

  1. High bandwidth mode: This mode offers an extremely high bandwidth of 5 MHz and a 15 MS/s sampling rate. SIRIUS XHS instruments can perfectly acquire impulse, step, and square signals without any ringing or overshooting. Such a mode is perfect for transient recording and applications such as power analysis. Such acquisition mode is typically found in SAR ADCs.
  2. High dynamic alias-free mode: This mode is used with sampling rates up to 1 MS/s. The data is acquired with a dynamic range of up to 150 dB. The alias-free filter with a bandwidth close to the Nyquist criteria is used for frequency domain analysis of signals like sound and vibration (NVH). This behavior is very similar to Sigma-Delta ADCs.

By today’s data acquisition standard, you would need two totally independent data acquisition devices for the measurements mentioned above. The SIRIUS XHS DAQ systems allow you to select the sampling rate independently per channel. This ensures that all measurements fit your current testing application. All modes are available on one device and can also work in parallel – acquiring two channels at different rates, bandwidths, and dynamic ranges completely synchronous with each other.

High-end signal conditioning amplifiers

The SIRIUS XHS provides several amplifiers that utilize our new HybridADC technology. The input channel configuration can be freely configured with one of the following signal amplifiers:

  • XHS-HV: Highly isolated CATII 1000V amplifier. Measure in a range of 20 V to 2000 V peak directly. 5 MHz bandwidth. 0.03% accuracy. This amplifier is perfect for the direct connection of high-voltage signals.
  • XHS-LV: Highly isolated voltage input amplifier. Measure in a range of 0.05 V to 100V. 5 MHz bandwidth. 0.03% accuracy. It offers sensor excitation. This amplifier is perfect for a direct connection of low voltage signals and current transducers.
  • XHS-ACC: Highly isolated IEPE/ICP and voltage input amplifier. Offers 2 mA – 20 mA IEPE excitation current. Offers TEDS support and high-temperature stability.

Noise floor, common-mode rejection, and gain and offset drifts at lower sampling rates are comparable to the SIRIUS DualCoreADC amplifiers. SIRIUS XHS amplifiers are perfect for high-speed data acquisition, transient recording, e-mobility measurements, and power analysis where the highest precision is an absolute necessity.
