Ultra-high precision, PCIe digitizer card hits 125 Msps on up to 16 channels

An ultra-high precision, PCIe digitizer card called the DN2.59x digitizerNETBOX series has state-of-the-art, 16-bit ADC technology to 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 MegaSamples per second on each channel. Typical applications include automated testing, communications, science and ultrasound.

Controlling and accessing the data collected by the digitizerNETBOX is done by simply connecting it with GBit Ethernet to a host computer (e.g. laptop or workstation) 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.

SBench 6 comes as standard with the products. It lets users control all the modes and settings of the hardware via a simple, easy-to-use, interface. 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 Ω and 1 MΩ) and calibrated gain with ranges from ±200 mV to ±10 V 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.

The units include an array of smart triggering capabilities and acquisition modes. Triggering on problem signals like glitches, spikes, bursts, or even when specific patterns occur, allows storing the recorded waveforms in the most memory efficient way possible. Transient capture, Multiple (burst) Recording, Gated Sampling, ABA sampling and data streaming (FIFO) modes are all supported.

The DN2.59x series digitizerNETBOX products are available immediately with prices starting from $9,300 and come with a full 5 five years product warranty as standard.
