200 MSPS digitisers join Ethernet/LXI instrument range
The three models (DN2.203-02,-04 and -08) come with two, four or eight channels. Each channel has its own 100 Msamples/sec, 8-bit ADC and an independent amplifier. The amplifiers have calibrated gain and signal offset so that measurements can be made using the full dynamic range of the ADC. All the channels are synchronously clocked, minimising phase error and allowing inter-channel measurements to be made with the best possible precision. Channels can be combined to allow faster 200 Msamples/sec sampling rates.
Digitised signals are stored in large on-board memories (up to 2 x 4 Gsamples) making it possible for the digitizerNETBOX to acquire, store and analyse very long and complex waveforms. For example, at a sampling rate of 100 Msamples/sec you could synchronously acquire eight different signals, with each lasting up to ten seconds.
A range of features suit these units to general purpose, remotely controlled, signal acquisition and measurement, including smart triggering capabilities and acquisition modes. Trigger on problem signals like glitches, drop-outs and bursts, or even when specific patterns occur, and then store the recorded waveforms in the most memory efficient way possible. Transient capture, gated sampling, data streaming and chart recorder modes are all supported.
To control and access the data collected by the digitizerNETBOX, connect it via GBit Ethernet to a host computer or anywhere on the corporate network. The instrument is fully LXI compliant (following Core 2011 specifications) and offers an IVI compatible interface for the IVI Scope and IVI Digitizer classes. You can write your own control program using almost any popular language including, Visual C++, Borland C++, Gnu C++, Visual Basic, VB.NET, C#, J#, Delphi and Python code. Alternatively, you can run Spectrum’s own software SBench6-Pro. SBench6 comes as standard with the products to control all the modes and settings of the hardware. The software also has features for data analysis and documentation, including FFT analysis, XY display, a function interpreter, several integrated analysis functions, export into ASCII, Wave, MATLAB, comment functions for annotating signals or displays and even a simple printout function.
