Integrated data acquisition system replaces modular units

Spectrum's digitizerNETBOX is aimed at industrial users, research and development departments, and engineers, who need a high-precision, multi-channel measurement system. The digitizerNETBOX comes complete with software and, when connected to a PC or company network, provides a total measurement solution.

The digitizerNETBOX is a fully integrated solution that can replace a current solution of an assembly of industrial PC, digitiser card, software etc. often from different sources: it is ready-to-use, straight out of the box providing a pre-tested and configured solution. It is compact and can be used for mobile applications unlike an industrial PC-based solution."

The digitizerNETBOX is available with two to 16 channels of fully synchronous data acquisition. Each channel has its own ADC and its own pre-amplifier, with either 8 or 16 bit resolution and sampling rates up to 200 Msamples/sec.

Each amplifier can be individually configured to allow the selection of several different input ranges (from ±50 mV up to ±10 V), 50 Ω or 1 M Ω input impedance and AC or DC coupling. Data is stored in an internal 1 GB (512 MSamples) memory and can be readout via Ethernet for processing and analysis. The 16 bit analogue inputs offer single-ended (referenced to ground) and true differential input mode. All inputs are equipped with BNC connectors eliminating the need for special cabling or adapters.

The unit has a range of recording modes and a comprehensive trigger engine. For example, the two external trigger sources, as well as each input channel, can all be used to produce a valid trigger. Users can select from edge, level, window, spike or pulse width trigger modes. Each individual trigger input can be combined with others to create conditional pattern triggers with standard AND/OR logic. Supported recording modes include single shot (Transient Recording), streaming (FIFO), segmented (Multiple Recording), gated (Gated Sampling) or the combination of segmented and slow chart recorder operation (ABA mode).

Controlling and accessing the data collected by the digitizerNETBOX is done by connecting it via GBit Ethernet to a host computer or anywhere on the corporate network. The platform is fully LXI compliant (following Core 2011 Specifications) and offers an IVI compatible interface for the IVI
