DG800 Series Overview

As a multi-functional signal generator, DG800 series function/arbitrary waveform generator integrates many
instruments into 1, such as function generator, arbitrary waveform gener a tor, noise gene r at or, pulse gener at o r,
harmonic generator, analog/digital modulator, and frequency counter. As a multi-functional and portable
instrument, it offers you a new choice in education, R&D, production, measurement, and other industries with
its user-friendly touch screen and high performance at an unprecedented price point.

Main Featur e s

 Unique SiFi II (Signal Fidelity II) technology: generate the arbitrary waveforms point by point; recover the

signal without distortion; sample rat e accu rate a nd adjusta ble; jit ter of all the output w avef orms (in cluding
Sine, Pulse, etc.) as low as 200 ps

 2 Mpts memory dept h (standard), 8 Mpts memory depth (optional) per channel for arbitrary waveforms
 Optional dual-channel with the same performance, equivalent to two independent signal sources
 High frequency stability: ±1 ppm; low phase noise: -105 dBc/Hz
 Built-in high-order harmonic generator (at most 8-order harmonics)
 Built-in 7 digits/s, 240 MHz bandwidth full featured frequency counter
 Up to 160 built-in arbitrary waveforms, covering the common signals in engineering application, medical

electronics, auto electronics, math processing, and other various fields

 Sample rate up to 125 MSa/s, vertical resolution 16 bits
 Arbitrary waveform sequence editing function available; arbitrary waveforms also can be generated

through the PC software

 Various analog and digital mo dulati on functions: AM, FM, PM, ASK, FSK, PSK, and PWM.
 Standard waveform combine functi on, capable of outputting specified wavefor ms combined with the basic

waveforms

 Standard channel tra cking fun ction, when ena bled, a ll the pa ra meters of both channe ls are updated base d

on users' configurations

 USB HOST&DEVICE interface (standard); USB-GPIB function sup p orted
 4.3'' TFT color touch screen
 RS232, PRBS, and Dualtone outputs supported
