High-speed 5 Gsample/sec LXI digitisers

April 27, 2015 // By Graham Prophet
For applications where fast electronic signals in the GHz range need to be remotely acquired and analysed, Spectrum has extended its digitizerNETBOX series of LXI based instruments and released eight new models.

Available with two, four or eight fully synchronous channels the units feature sampling rates up to 5 Gsample/sec, bandwidth in excess of 1.5 GHz and on-board acquisition memory up to 8 Gsamples. The combination suits the digitisers to capturing long complex high-frequency signals and for characterising fast timing events that go down to the nano- and sub-nanosecond ranges.

Fully LXI compliant, the digitizerNETBOX products allow remote control and data transfer over fast GBit Ethernet. Connect them directly to a Notebook or PC, or in fact to anywhere on a company LAN, and automated data acquisition becomes easy. Offering significant advantages in measurement speed, flexibility, size and channel density the products can be used to replace conventional bench instruments such as oscilloscopes, spectrum analysers, multi-meters, counters, timers and older generation digitiser products.

The digitizerNETBOX instruments include Spectrum’s powerful SBench 6 software that allows full instrument control, graphical display, data storage and analysis. The program offers both oscilloscope and transient recording modes, including continuous data streaming. A feature of SBench 6 is the segmented acquisition view for, for example, capturing burst type signals together with all the associated trigger time stamping information. SBench 6 can be used to measure parameters, perform FFTs and run a variety of different math and processing functions such as filtering, averaging and histograms. Data can be exported into a number of formats such as ASCII, Wave and MATLAB, allowing use of digitizerNETBOX products with a variety of third party software tools.

Users who want to control the digitizerNETBOX units with their own software can use the Spectrum drivers (available for Windows and Linux) that are included as part of the product. A set of standard programming examples illustrates the main signal capture functions and support is provided for Visual C++, Borland C++, Gnu C++, LabVIEW, Visual Basic, VB.NET, C#, J#, Python and Delphi code.

Eight different models include the DN2.225-08 with top of the range performance with
