HGL Data Recorders (HDR)

HGL Dynamics has developed the HDR family to provide simple multi-channel data recording without the need for additional PCs and software.

All HDR units include HGL’s standard interface connections presented on the Hardware Overview page. This means that all HDR units can connect with and operate with any other HGL Modular Front-Ends.

HDR family are presented in 3U Milled Aluminium Hard Anodised Chassis and can be used on a tabletop or in a 19” rack. Whilst the HDRs include their own touch based software they can also be controlled from HGL’s Data Acquisition Software.

Features

16 / 32 Input Channels

The HDR family currently includes two input cnannel configurations, 16 and 32.

16 / 32 Analogue Outputs

The HDRs can be configured to include 16 or 32 Analogue Output Channels powered by Delta-Sigma DACs driven by 24-bit data at up to 256kHz.
With the powerful FPGA on board this provides numerous processing / replay / passthrough options

Multiple Conditioning Types

Depending on Signal Conditioning option(s) chosen, HDR can support Voltage, IEPE, SE & DF Charge and 4-20mA on each channel.

Multiple Synchronizing Types

HDR natively supports IRIG A/B, IEEE-1588 (PTPv2) and HGL LVDS for precise synchronisation to < 50nS resolution across entire systems. GPS is optionally available.

Simultaneous Sampling

HDR supports individual Sigma-Delta ADCs per channel synchronized to better than 10ns across individual units.

Flexible Sample Rates

HDR allows sample rates from 1kHz to 256kHz (in 1Hz steps) to be chosen for each block of 8 channels. Due to careful design the majority of these sample rates are precise.

140dB Dynamic Range

HDR utilises instrumentation grade Sigma-Delta 24-bit ADCs across the range. These provide up to 140dB Dynamic Range and with oversampling rates to 1024x provide superb anti-alias capabilities.

Flexible Power

All HDR models support DC power from 9 to 36V (automotive ranges).
AC power supplies are supported through a range of external adaptors

Environmental

HDR has been designed to be used in relatively challenging environments and all models have no exterior openings and are sealed to IP64 (min) standard against water ingress.

Aided Conduction Cooling

All HDR models are primarily conduction cooled through innovative internal design and materials.
The need for the onboard PC module means that some external fan-based forced air cooling is required, but this is achieved without an external opeaning. HDR is able to operate accurately from -10 to +40C ambient.

Flexible and Scalable

Every HGL DAQ module is fully interoperable with other DAQ modules and this includes HDR. Connection of multiple units is simple and quick and allows complex systems up to and above 1000 channels to be realised easily

HDR Models

HDR is available in a range of models and signal conditioning options. The most popular units provide the same conditioning for all channels, but HGL Dynamics can provide mixed conditioning models on request.

The table below indicates the Signal Conditioning types in the first column and the types of conditioning supported by that type.
