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 eight fully synchronised channels each with over 1.5 GHz of bandwidth and a separate ADC capable of running at 1.25 Gsample/sec. For faster sampling the DN2.225-08 lets you combine channels to have four running at 2.5 Gsample/sec or two at 5 Gsample/sec. For cost effective solutions models are also available with 500 MHz bandwidth and lower maximum sampling rates.
All the digitisers are equipped with fully calibrated front-end signal conditioning circuits that offer input ranges from ±200 mV up to ±2.5 V full scale. Further signal conditioning can also be provided through the use of a range of optional amplifiers. Signal conditioning allows signals to be scaled correctly so that they use the full 8-bit dynamic range of the digitiser, optimising measurement accuracy and resolution.
