Waveform output
The Rigol DG800 Pro has multiple built-in waveforms, covering frequently used signals in engineering, medical electronics, mathematics and more.
- Output mode: Continuous, Modulation, Sweep, Burst, Sequence
- Standard waveforms: Sine, Square, Ramp, Pulse, Noise, Arb, Harmonic
- Arbitrary waveforms: 148 types of waveforms, including Sinc, Exponential Rise, Exponential Fall, ECG, Gaussian, HaverSine, and Lorentz
DG821 Pro | DG822 Pro | DG852 Pro | |
Sine | 1 μHz to 25 MHz | 1 μHz to 25 MHz | 1 μHz to 50 MHz |
Square | 1 μHz to 20 MHz | 1 μHz to 20 MHz | 1 μHz to 40 MHz |
Ramp | 1 μHz to 1 MHz | 1 μHz to 1 MHz | 1 μHz to 1 MHz |
Pulse | 1 μHz to 10 MHz | 1 μHz to 10 MHz | 1 μHz to 25 MHz |

Various modulation types
The DP800 Pro supports various analog and digital modulation types including AM, FM, PM, ASK, FSK, PSK and PWM. Both internal and external modulation sources are available for different test scenarios.
Low jitter
RIGOL’s unique SIFI II technology generates arbitrary waves point by point, restoring signals without distortion.

Frequency counter
This instrument includes a standard 7-digit counter with maximum frequency of 500 MHz. Equipped with an independent input connector for counter measurements, it provides a more simplified and accurate way to measure frequencies.
Multiple connectivity options
The DG800 Pro contains various interfaces including USB Host, USB Device and LAN (LXI Core 2011 Device) and can be operated remotely via Rigol’s Web Control.
The instrument can also be powered from a mobile power source through its USB-C port. Please note, mobile power source not included.


Rear panel VESA mount
The rear panel of the DG800 Pro contains a 100×100 VESA mounting pattern. This enables easy connection to a mounting arm, saving valuable space on your bench. Please note, arm sold separately.
