Spectrum Instrumentation DN6.65x series generatorNETBOX multichannel AWGs

Designed for engineers and scientists that need to simultaneously generate multiple electronic test signals, Spectrum Instrumentation’s DN6.65x series of generatorNETBOX arbitrary waveform generators (AWGs) offer 24 to 48 synchronous channels in a single rack unit.

Suitable for multichannel automated testing applications, the eight different variants achieve full remote control through a simple Ethernet connection to any PC or local area network (LAN). The units feature 16-bit digital-to-analog converter technology and combine this with low-noise flexible outputs, allowing them to generate almost any test signal in the DC to 60 MHz frequency range.

The instruments are available with 24, 32, 40 or 48 fully synchronous channels. To handle different signal generation requirements, users can select from models that offer output rates of either 40 or 125 MS/s. Each channel has its own DAC that is synchronously clocked using a phase-locked loop (PLL) control system.

Four different filters are available to optimise the output signal quality and to help ensure good dynamic performance; noise spectral density (NSD) is as low as -142 dBm/Hz, total harmonic distortion (THD) is down to -74 dB, signal-to-noise ratio (SNR) is as high as 90 dB and spurious-free dynamic range (SFDR) is up to 97 dB. This high dynamic performance allows users to create and replay precise test signals and waveforms.

A wide range of signal amplitudes can be generated with programmable output swings of up to ±6 V into high impedance or ±3 V into 50Ω. The units include large onboard memories (up to 6 x 512 MS) that can be utilised in a number of different operating modes to allow the generation of long and complex waveforms.

The self-contained AWGs come with all the tools necessary to generate an unlimited variety of waveforms. Simply connect them to a host computer or anywhere on the corporate network and start up Spectrum’s SBench 6 Professional software, included with every unit. The AWGs also come with front-panel multipurpose I/O connectors, which give access to synchronous digital (marker) outputs, trigger output, the instrument’s run and arm status, the PLL reference clock or asynchronous I/O lines.
