HGL Hawk data acquisition

High-Performance Data Acquisition and Monitoring

  • Affordable high-quality multi-channel data acquisition
  • Up to 64 channels per acquisition unit
  • Control in excess of 1024 channels from one screen with multi-unit facility
  • Standard: 0 - 256 kS/s sample rate (0 - 100 kHz bandwidth) per channel
  • High-speed:
    • 0 - 2 MS/s sample rate (0 - 1 MHz Bandwidth) on all channels
    • 4 MS/s sample rate (measuring every second input)
  • > 90 dB SNR
  • Simultaneous sampling across all input channels
  • Built-in real-time monitoring and detailed analysis tools
  • Full network/Internet connectivity
  • Remote control and interrogation facilities
  • PC architecture


Acquire hundreds of analogue or digital dynamic data channels, with simultaneous sampling across all channels, and analyse the results within seconds - all on a single compact data acquisition system. A Hawk system delivers that solution today.

The Hawk system provides a range of modular multi-channel data acquisition and processing units. The Hawk range is able to acquire data from a wide range of analogue and digital sources. The built-in data analysis unit is capable of reducing the acquired data into meaningful results in either the time or frequency domains.

The Hawk has many applications and is particularly appropriate for those requiring high channel-count, long-duration, high-resolution dynamic data capture at fixed test locations.

  • Medium/large scale gas/steam turbine and compressor development test facilities
  • Vibration analysis systems for reciprocating engines
  • Structural vibration monitoring
  • Noise monitoring and analysis
  • Very high-speed data logging (50 MB/second per unit and above)
  • Seismic data capture and analysis

Hawk units are available in several flavours:



These systems feature analogue input from 32 or 64 channels respectively, using true simultaneous sampling across all channels, at up to 256 kS/s sample rate per channel. For higher sample rates, please consider the High-Speed Hawk alternative. Analogue input Hawks can be connected together with LVDS synchronisation, forming systems of much larger capacities - and all controlled from one Hawk User Interface screen.


This system detects, decodes and records digital telemetry streams from multiple sources, such as may be found in a development test cell for rotating machinery. A single HawkDigital can support up to eight telemetry streams at once. The HawkDigital can be linked with other Hawk units as part of a larger test cell system. All captured data is written to time-stamped files which are then stored in the Hercules data management database.

High-Speed Hawk

This system features HGL's high-speed acquisition cards to cater for specialised applications such as rotating turbo-machinery monitoring from fixed casing sensors, or for acoustic emissions measurements. When all fitted input channels are in use, the high-speed Hawk can record data at rates up to 2 MS/s per channel. Operating with only half of the input channels being measured, this maximum rate can be doubled up to 4 MS/s per measured channel. The entire system can then be controlled from one Hawk User Interface screen.


This system is used alongside the Eagle platform, for harsh environments where it is not advisable to put computers with disk drives and moving parts close to the equipment under test. Instead, the Hawk captures and processes real-time data streamed from a remote acquisition device such as a Dragonfly or an Eagle.
