Spectrum Instrumentation Corp. (Hackensack, NJ) introduced the DN6.44x, a range of 12 high-speed, 14-, and 16-bit LXI-based digitizers with up to 24 fully synchronized channels. The 16 bit ADC models offers sampling rates of either 130 MS/s or 250 MS/s, while the 14 bit units feature sampling rates of 500 MS/s. The units are suitable for applications where arrays of receivers, sensors, detectors, rectifiers, antennas and other electronic devices are to be used and tested. Each channel is also equipped with its own front-end amplifier that features six input ranges (from ±200 mV up to ±10 V full scale), switchable input impedance (50 Ω and 1 MΩ) and programmable positive input offset for unipolar signals. Analog bandwidth is as high as 250 MHz (for 500 MS/s models), enabling the units to capture electronic signals in the DC to 200 MHz frequency range. The instruments are equipped with a large on-board acquisition memory of 512 MSamples per channel.
