SIRIUS® XHS​​​​​​​ highlights

HybridADC signal conditioning technology

HybridADC delivers the best of both worlds, combining high bandwidth and dynamic acquisition capabilities. It features 16-bit ADCs with up to 5 MHz bandwidth and a sampling rate of up to 15 MS/s for high-speed data collection. Additionally, it offers high-dynamic, alias-free acquisition with a sampling rate of up to 2 MS/s. 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 modes of 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 operates at sampling rates of up to 2 MS/s, acquiring data with a dynamic range of up to 150 dB. It employs an alias-free filter with a bandwidth closely aligned with the Nyquist criterion, making it ideal for frequency domain analysis of signals such as sound and vibration (NVH). This performance closely mirrors that of Sigma-Delta ADCs.

By today's data acquisition standard, you would need two 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 200 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 100 V. 5 MHz bandwidth. 0.03% accuracy. It offers sensor excitation. This amplifier is perfect for directly connecting 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.

Amplifiers overview

SIRIUS® XHS data acquisition systems can use any of the available amplifiers. 8 amplifiers (analog input channels) can be installed in one SIRIUS® XHS modular chassis. You can mix different amplifier types and select your custom front-end, the way it suits your needs.

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.

SIRIUS® XHS digital counter inputs

As highlighted earlier, the SIRIUS® XHS data acquisition systems boast Dewesoft's cutting-edge SUPERCOUNTER® technology across all eight counter inputs. The counter inputs are available for all SIRIUS® XHS instruments, providing users with enhanced counter/encoder input capability.

Conveniently located on the back panel of the SIRIUS® XHS instrument, the counter inputs ensure easy accessibility and seamless connection of all sorts of counter and encoder sensors via the LEMO 1B 7-pin female connectors.

The counters boast a timebase of 150 MHz, a maximum bandwidth of 15 MHz, and a 32-bit resolution. Dewesoft SUPERCOUNTER® features advanced input filtering to address glitching issues. Counter inputs are compatible with 3.3 V TTL/CMOS logic levels.

SIRIUS® XHS counter inputs support all these modes:

  • Event counting

  • Waveform timing

  • Encoder

  • Tacho

  • Geartooth

Each counter channel comes with three standard inputs (A, B, Z) necessary for encoder applications. It also provides +12 V and +5 V for sensor supply, along with digital output for alarming and fast triggering.

The counter channels can also be used as a digital output. Digital outputs utilize 5 V push-pull logic with a fast triggering option. The triggers out module enables digital outputs based on custom conditions. Either from the analog input channel or digital input channel. This trigger option operates in real-time on the hardware itself. Users have the flexibility to customize the shape of the output pulse in terms of delay and duration.

The total response time can go below 500 ns, proving beneficial in time-critical applications such as emergency shutdowns or alarms.

PTP synchronization

SIRIUS® XHS instruments utilize Precision Time Protocol (PTP) synchronization. The Precision Time Protocol is a protocol used to synchronize clocks throughout a computer network.

If you combine and mix analog channels coming through Sigma-Delta and SAR ADCs (high-bandwidth and alias-free), channels are delayed due to the sigma-delta filter group delay. SIRIUS® XHS can run both modes perfectly aligned and synchronized. This is achieved by the nature of the HybridADC and filtering design.

Multiple SIRIUS® XHS devices can be connected together in synchronization with each other using the PTPv2 synchronization method, IRIG, NTP, or PPS signal. This provides absolute time synchronization using in-house time servers or GPS time.

SIRIUS® XHS is also backward compatible and it can be synchronized with any other Dewesoft data acquisition devices like standard SIRIUSKRYPTONIOLITEDEWE-43A, etc.

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.

Intuitive and easy to use

Using Dewesoft data acquisition systems does not require any complex configuration setups or programming knowledge. We also kept this in mind when designing SIRIUS® XHS.

Plug-and-play technology with smart sensors and advanced TEDS is supported by default. This makes performing measurements with the Dewesoft DAQ systems easier than riding a bike. You will be ready to measure in no time. 

Getting precise and graphically rich results is easier than ever. The drag-and-drop user interface of bundled DewesoftX software will allow you to define your measurement screens and results in no time. A rich mathematics library for signal processing is also available one click away. Just connect the right widget with your input channel and Voila! Works like magic.

Great connectivity with open and standard data protocols

SIRIUS® XHS has two ways of transmitting the data to the PC:

  • Ethernet interface (GLAN): perfect for distributed data acquisition.

  • USB 3.0 (Type C connector): perfect for very high-speed data acquisition.

SIRIUS® XHS acquires data with a very low load on the computer's CPU. It uses a​​​​​​​ DMA transfer on the system level to reduce loads.

In today’s world of open toolchains and intercommunication, devices should be compliant with standard protocols. SIRIUS® XHS can serve acquired data via these protocols, all in parallel to storing data on a PC running DewesoftX software.

  • OPC UA: This is the industry standard and is a perfect framework where the devices can be integrated into any system, including SCADA, MES, ERP, and others.

  • XCP: XCP is a very widely used protocol in the automotive industry for data exchange. In modern vehicles, the required data bandwidth is higher than ever. 1 GBIT XCP interface allows data transfers with as high as 1 Ms/s.

  • CAN and CAN FD: Vehicle bus systems can be read through the included CAN FD interface. At the same time, SIRIUS XHS allows the measured data to be transmitted in the CAN FD format.

Expand channel count and distribute measurement

SIRIUS® XHS slices can be used as a stand-alone DAQ device or stacked and daisy-chained together into a larger channel count system. Stacking systems together is made simple with easy click-mechanism.

If you need a distributed data acquisition system, then SIRIUS® XHS devices can easily be distributed via the GLAN interface. Data and PTP synchronization are available with a single ethernet cable running from node to node.

SIRIUS® XHS devices are also compatible and can be interconnected with other Dewesoft DAQ systems like SIRIUS, KRYPTON, or IOLITE.

Working with multiple SIRIUS® XHS instruments is as easy as working with a single unit. Configuration is seamless inside our DewesoftX data acquisition software.

Next-gen power and power quality analyzer

The SIRIUS® XHS is a cutting-edge power analyzer capable of capturing voltage and current signals at up to 15 MS/s and with a 5 MHz bandwidth. This makes it exceptional for electrical power and power quality analysis, delivering the highest precision possible.

Bundled with DewesoftX software, the SIRIUS® XHS includes a power analysis module that calculates various power and energy parameters, such as P, Q, S, D, power factor, and Cos φ for each harmonic, among many others.

The SIRIUS® XHS stores raw data from all connected channels and automatically calculates the specified power, power quality, and mechanical parameters. These parameters can be visually displayed in multiple formats, including recorder graphs, digital and analog displays, scopes, and vectorscopes.

Leveraging a computer graphics card (GPU) as a multi-threaded calculation platform, the DewesoftX software and its power module can compute power parameters at full 15 MS/s sampling rate for multiple phases in real-time.
