Multi-channel LXI Digitizers Deliver High Resolution Measurements | Spectrum
The high sampling rates and resolutions make the DN6.44x series perfect 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 ±10 V full scale), switchable input impedance (50 Ω and 1 MΩ) and programmable positive input offset for unipolar signals.
The 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.
Easy signal capture
Each DN6.44x instrument is equipped with a large 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 as well as two external inputs can act as a trigger source with the capability of combining all sources by AND/OR logic function.
The different acquisition modes, which include single shot (Transient Recording), streaming (FIFO), segmented (Multiple Recording), gated (Gated Sampling) or a combination of segmented and slow chart recorder operation (ABA mode), can be combined with internal trigger time stamping.
Perfect for remote and automated applications
The units feature an industrial chassis with integrated cooling, a replaceable dust filter and low noise power supplies. Front-panel SMA connectors are used for the channel inputs, external clock and external triggering, while LED lights provide a visual indication for the power, trigger and LAN status.
