16bit data acquisition over 48 channels at 125Msample/s

  • Author:Ella Cai
  • Release on:2018-07-26
Spectrum Instrumentation has added twelve new products to its family of German-made LXI-based digitizerNETBOX data acquisition instruments.

Designed specifically for situations where multiple signals need to be acquired, stored and analysed, users can select from models that provide 24, 32, 40 or 48 synchronised channels.

Called the DN6.59x series, the digitisers are all based on 16bit ADCs (up to 81dB signal-to-noise, up to 103dB spurious-free dynamic range and down to -86dB total harmonic distortion) and come with a choice of maximum sampling rates (20, 40 or 125Msample/s) and bandwidths (10, 20 or 60MHz).

While each channel has its own ADC and signal conditioning circuitry, all the ADC’s all share a common clock – which is where the synchronisation comes from, “and have zero phase error”, claimed the firm. “The design of the clocking system ensures that cross channel timing measurements are made with the highest possible precision while the independent signal conditioning enables the units to be used with signals that have a wide range of amplitudes.”

The gain of input amplifiers can be programmed for ranges between ±200mV and ±10V, input offset (for unipolar measurements) and termination resistance (50Ω 0r 1MΩ).

Inputs can be single-ended or differential.

Multiple triggering options are provided, as are a number of intelligent acquisition modes, all backed by on-board memory.

“They should be of interest to everybody working with multiple signals, such as those produced by arrays of sensors, receivers, detectors or antennas, and also to users who need to test signals from multiple electronic components or test points,” said Spectrum CTO Oliver Rovini. “As such, we believe the instruments will find wide application in areas such as ultrasound, lasers, communications, lidar, radar, power, physics, automotive, medical and materials science, as well as general electronic test and measurement.”

Remote control is via Gbit Ethernet to a host laptop, workstation or corporate network.

The platform is LXI compliant (following Core 2011 Specifications) and offers an IVI compatible interface for the IVI Scope and IVI Digitizer classes.

Users can write their own control program using languages including C++, LabVIEW, MATLAB, VB.NET, C#, J#, Delphi, Java and Python code – or users can run Spectrum’s own ‘SBench 6 Professional’ software which comes as standard with the digitizerNETBOX.

The in-house software allows control of all modes and settings, and has handles waveform display, data analysis and documentation. Included is FFT analysis, XY display, a function interpreter, parameter measurements, export into ASCII, Wave and MATLAB.

There is an SDK for both Windows and Linux.

The warranty is five years.
