Function presentation

4.3-inch touch screen

The 4.3-inch TFT color touchscreen is enhanced with a new User Interface design.

16-bit vertical resolution

DG800 series generators extend the output with 16-bit resolution.

The output voltage resolution is 4 times higher than the

in traditional 14-bit generators. The DG800 reproduces any

waveform more reliably and improves signal performance.

Signal jitter as low as 200ps

The DG800 series function/arbitrary waveform generator is based on

based on SIFI II technology developed by RIGOL. It can generate

arbitrary waveforms point by point and restore the signal without distortion.

The sampling frequency can be precisely adjusted,

Compared with traditional DDS signal source, the signal jitter is lower,

and the jitter of all output signals can reach only 200ps.

SiFi II Technology

Sifi II technology allows for flexible signal reproduction through

filtering options such as stepping, smoothing and interpolation.

These options in the signal sorting function can provide precise

roll-down control for the selected signal. By combining these flexible

playback options or using edge timing in interpolation mode,

you can easily define the range of broadband components in a signal.

Supports multiple signal outputs

Supports PRBS, RS232 and sequencing output

Arb sequencing

Create and combine complex signal sequences for restoration

or fault analysis at the touch of a finger.

This function combines cycles of different waveform types, including two-tone,

arbitrary waves or noise, to mimic a wide set of test signals.

Quiet fanless operation

The design's fanless design, allows it to operate

without unnecessary sound interference.

Harmonic generator

The DG800 has a built-in harmonic generator function.

It outputs harmonic signals with specific times,

amplitude and phase. It is typically used for equipment testing

detection or harmonic filtering.

200MHz Frequency Meter

Provides a 7-bit frequency meter measurement function,

Which can measure frequency, period, duty cycle,

positive pulse width, negative pulse width and other parameters of the

external input signal, and also supports statistics of measurement results.

Touch user interface

Ultra-modern, convenient "tap & drag" ("touch and drag") function streamlines the use of menus; parameters can be entered via the on-screen keyboard.

SUPPORT FOR ADVANCED WAVEFORMS: PRBS, RS232, Sequence

0dB NOISE WHEN OPERATING with fan off. An all-new heat dissipation structure design has been subjected to rigorous thermal simulation tests to ensure stable operation in harsh environments.

FEATURES: BURST (pulse packets), SWEEP (frequency sweep).
