Data Acquisition
When and Where You Need It

Distributed and Stand-Alone Data Acquisition

The DAXUS® DXS-R is a versatile data acquisition solution for local or distributed measurements. Units can be connected directly to a host PC, operate as stand-alone high-speed data loggers, or deployed as part of a distributed measurement system spanning large distances. The built-in hard drive and internal battery ensure data is saved during network or power outages. Its small size and rugged packaging make it ideal for use in the lab, field, or production environment.

Product Overview


Daxus units feature two slots that accept a variety of input modules. Each system can acquire up to 48 channels with sampling rates up to 200 kS/s per channel or as low as one sample per minute for long term monitoring. Multiple Daxus units can be stacked to increase the number of channels, and all inputs can be synchronized by sharing clock signals or via GPS or IRIG2.

The Daxus system supports three different sampling rates per channel which allows you to acquire high speed and low-speed data simultaneously and reduce file sizes. You can also create triggers to start and stop recording based on any input channel, event (e.g. external trigger signal), or a specific date and time.

The Utility / DIO port contains alarm inputs, alarm outputs, programmable outputs, and inputs for external sample clocks eliminating the need for a separate digital I/O module. Optional interfaces include IRIG for synchronizing data across multiple units, GPS for time and location, and CAN for vehicle applications. Selecting these options does not require you to give up a slot for input modules.

The Daxus architecture provides advanced digital signal processing (DSP) technologies that allow you to configure custom filters and perform frequency measurements on a per-channel basis.

Reduce testing costs and increase flexibility with the UNIV-4 universal input module. The UNIV-4 alleviates that need for dedicated modules by allowing you to perform voltage, DC bridge, thermocouple, RTD, and IEPE accelerometer measurements in a single module.


All systems come with the easy to use Daxus application software for the PC which allows you to configure systems, view data in real-time, review saved data, and transfer or copy data from the Daxus to your PC. In networked applications, you can connect to any unit from any PC on the network. Reviewing or transferring data during a capture does not interrupt the current acquisition.

Scope Mode is a powerful feature that allows you to acquire and save data at low sample rates while capturing high-speed snapshots based on user-defined triggers. This is particularly useful for capturing intermittent signals or analyzing the timing between signals. Icons on the real-time display indicate when a scope capture has occurred and trigger events are embedded in the data file. High-speed data from scope capture is saved in separate files and can be viewed in a scope-like display with high time-base resolution and cursor measurements without interrupting long term trending.


Daxus provides powerful tools to help you analyze data quickly and easily.

The derived channel feature allows you to create up to six calculated channels or combine any four channels based on user-defined equations. Derived channels are calculated in real-time and can be displayed and recorded along with the original input channels in real-time or review mode. You can also apply advanced filtering options post-capture.

To aid in analyzing acquired data, cursors provide built-in measurements such as average, Min-Max, Peak-Peak, slope, RMS, Sum, Std Deviation, and others. You can also configure Fourier Transform Windows for viewing and analyzing frequency content in real-time.

Advanced counter functions based on DSP technologies allow many common frequency measurements and eliminates the need for a separate counter/timer module – regardless of the input module type. Available functions include frequency, duty cycle, edge separation, quadrature encoder, gated pulse counter, pulse width, and more.

User notes can be added during an acquisition and are saved as part of the data file for later review.

Analysis and control functions can be extended and automated using Python scripting or LabVIEW.


With Daxus, all data is stored locally on an internal hard drive and streamed across the network on demand. This ensures that critical data is always captured regardless of network reliability. Choose from a 500 GB hard disk drive (standard) or optional solid-state drives for rugged environments and faster read/ write spreads.

Store derived channels, events, and notations along with measurement data to reduce post-processing and recall important events. Export only the channels or timeframe selected to ASCII using the application Daxus software. AstroNova also provides the free AstroVIEW X software for viewing data from any AstroNova data acquisition system and exporting to other common file formats.

The built-in Lithium-Ion battery automatically charges when the system is connected to power and provides backup power for continued operation and no loss of data in the event of a power outage.


Daxus PC software enables the user to print data to a PDF file or printer in real-time, scope, or review modes.


Each Daxus chassis features two slots for the signal input module, to configure your Daxus system-wide variety of input modules.

Channel meters provide a way to view any channel as a digital readout, bar meter, moving needle, or analog gauge making it easy to view current values at a glance. Visualize the relationships between inputs by plotting them in XYY plots. Channel meters and XYY plots can be sized and placed anywhere on the display for easy viewing. For viewing data on the go, AstroNova offers the Daxus mobile app which allows viewing data in real-time, review data files, and receive alerts on a smartphone or tablet.
