Twelve new instruments with up to 24, fully synchronized channels extend Spectrum's digitizerNETBOX family. The 16-bit ADC models offer sampling rates of either 130 Msamples/sec or 250 Msamples/sec, while the 14-bit units feature sampling rates of 500 Msamples/sec.
The high sampling rates and resolutions suit the DN6.44x series for wide-band signal capture. The high channel density makes the instruments suitable for applications where arrays of receivers, sensors, detectors, rectifiers, antennas and other electronic devices are to be used and tested.
To ensure all models deliver excellent cross channel timing capability with minimal phase error, the ADCs on each channel are clocked synchronously. Each channel is also equipped with its own front-end amplifier that features six input ranges (from ±200 mV up to ±10V full scale), switchable input impedance (50Ω and 1 MΩ) and programmable positive input offset for unipolar signals.
The analogue bandwidth is up to 250 MHz (for 500 Msample/sec models) enabling the units to capture electronic signals in the DC to 200 MHz frequency range. Each DN6.44x instrument is equipped with on-board acquisition memory of 512 MSamples per channel and advanced trigger circuitry to allow the capture of the widest range of input signals. Each channel can act as a trigger source, as well as two external inputs, with the capability of combining all sources by AND/OR logic function.
Based on the LXI instrumentation standard (following the LXI Device Specification 2011 rev. 1.4), the digitizerNETBOX products are also designed for automated testing and remote applications. Full remote control is achieved through a simple GBit Ethernet port, which allows connection to any PC or local area network (LAN). Spectrum's SBench 6-Pro software is provided as standard with every unit.
This software lets the user control all the operating modes and hardware settings from one simple, easy-to-use, graphical user interface and has a host of built-in features for waveform display, data analysis and documentation. Acquired and
