Spectrum Instrumentation has added twelve members to its family of LXI-based digitizerNETBOX data acquisition instruments. Designed for situations where multiple signals need to be acquired, stored and analyzed, users can select from models that provide 24, 32, 40 or even 48 fully synchronized channels.
The latest DN6.59x series digitizers are all based on high-resolution 16-bit ADC technology and come with a choice of maximum sampling rates (20, 40 and 125 Msamples/s) and bandwidths (10, 20 and 60 MHz) to best match applications found in a wide variety of industries. It's a combination that makes these new instruments ideal for use in multi-channel applications where signals, in the DC to 60 MHz frequency range, need to be acquired and analyzed with the highest precision and accuracy.
Importantly, each channel of a digitizerNETBOX has its own ADC and signal conditioning circuitry. The ADC's all share a common clock so that the acquisitions made on all the channels are fully synchronous and have zero phase error. The design of the clocking system ensures that cross channel timing measurements are made with the highest possible precision while the independent signal conditioning enables the units to be used with signals that have a wide range of amplitudes. Each channel has its own programmable input amplifier, with ranges between ±200 mV and ±10 V, input offset for unipolar measurements, termination of 50 Ohm and 1 MΩ and an integrated calibration circuit. The inputs also feature single-ended and true differential channel modes.
