16-bit ADC 16-channel digitizer supports 125MS/s per channel

May 17, 2018 // By Julien Happich
Spectrum Instrumentation has announced stand-alone versions of its recently launched, ultra-high precision, PCIe digitizer card in a range of self-contained digitizers, the DN2.59x digitizerNETBOX series.

With state-of-the-art, 16-bit ADC technology, the instruments deliver 256 times more resolution than the usual 8-bit technology. The range includes models that offer 4, 8 and 16 channels and a choice of sampling rates up to 125 MSamples per second on each channel. Controlling and accessing the data collected by the digitizerNETBOX is done by simply connecting it with 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 Scope and Digitizer classes. Users can write their own control program using almost any popular language including, C++, VB.NET, C#, J#, Delphi, Java and Python code. Alternatively, they can simply run Spectrum's own software, SBench 6 Professional. The software also has a host of built-in features for data analysis and documentation. These include FFT analysis, XY display, a function interpreter, parameter measurements, export into ASCII, Wave, MATLAB, comment functions (for annotating signals or displays) and even a simple report and printout function.

The DN2.59x series products also provide software selectable, single-ended and differential input modes. Each channel has its own ADC and an independent amplifier. The amplifiers have selectable input impedance (50 Ohms and 1 MOhms) and calibrated gain with ranges from ±200 mV to ±10V full scale. Variable gain allows input signals to be scaled so that they cover the full dynamic range of the ADC and therefore maintain the best possible measurement accuracy. All the channels are synchronously clocked so that phase error is minimized and inter-channel measurements can be made with absolute precision. Large on-board memories also make it possible to acquire and store the longest and most complex of waveforms.
