The RIGOL DG900 Pro Series combines dual-channel function and arbitrary waveform generation with up to 200 MHz output frequency, a 1.25 GSa/s sample rate and 16-bit vertical resolution. Each channel includes 16 Mpts of arbitrary waveform memory as standard, supporting detailed signal creation for electronics development, communication experiments and automated testing.
Seven integrated functions cover standard, arbitrary, noise, pulse and harmonic generation, analog and digital modulation, and independent frequency measurement. A 7-inch touchscreen, Web Control, SCPI commands and USB-C power support allow the instrument to adapt to interactive laboratory work, networked automation and portable testing.
Key Features

Two equivalent output channels: Generates two independent or related signals for multi-stage circuits, differential testing and synchronized stimulation.
-
Up to 200 MHz output frequency: Three models provide 70, 150 or 200 MHz maximum output to match different signal-bandwidth requirements.
-
1.25 GSa/s sampling: Supports point-by-point arbitrary waveform generation with detailed reproduction of fast signal changes.
-
16-bit vertical resolution: Provides fine amplitude control for waveform simulation and circuit-response measurements.

16 Mpts per channel as standard: Stores long user-defined waveforms, with an optional upgrade to 32 Mpts per channel.
-
Comprehensive modulation: Supports AM, FM, PM, ASK, FSK, PSK, PWM and SUM modulation for communication, control and power-electronics experiments.
-
Up to 20th-order harmonic generation: Creates signals with controlled harmonic content for filter and amplifier response testing.
-
Independent 1 GHz counter: The 7-digit frequency counter measures an external signal without occupying either waveform output channel.
-
Sequence generation: Combines up to 64 waveform events with as many as 256 repetitions for multi-stage and repeatable test signals.
-
7-inch color touchscreen: Allows both channel waveforms to be configured, viewed and edited through a clear graphical interface.
7-in-1 Signal Generation Platform
The DG900 Pro Series integrates the following functions into one instrument:
- Function generator
- Arbitrary waveform generator
- Noise generator
- Pulse generator
- Harmonic generator
- Analog and digital modulator
- Frequency counter
This integrated platform reduces the need to switch between separate signal sources and frequency-measurement equipment during circuit development and functional testing.
Arbitrary Waveforms and Sequence Mode
RIGOL SiFi II technology generates arbitrary signals point by point with an accurately adjustable sample rate. Output jitter reaches as low as 200 ps RMS, supporting repeatable waveform timing and detailed signal reproduction.
Each channel provides 16 Mpts of arbitrary waveform memory as standard. The DG900 Pro-3RL option expands this capacity to 32 Mpts per channel. Sequence mode can combine up to 64 waveform events and apply up to 256 repetitions for complex or multi-stage test procedures.
Pulse, Modulation and Harmonic Generation
The DG900 Pro Series supports square-wave output up to 60 MHz and adjustable-edge pulse output up to 50 MHz, with rise times as low as 3 ns. These capabilities support digital circuit stimulation and transient-response testing.
AM, FM and PM provide analog modulation, while ASK, FSK and PSK support digitally modulated signals. PWM and SUM modulation extend the platform to motor-control, switching-power and multi-signal simulation tasks. The harmonic generator creates signals containing harmonics up to the 20th order for device and filter evaluation.
Independent Frequency Measurement
The built-in 7-digit counter measures external signals up to 1 GHz through an independent input. Users can measure an incoming frequency while both generator channels remain available for waveform output, reducing the need for a separate counter in many test setups.
Connectivity and Remote Control
USB and LAN interfaces support computer connection, data transfer and test-system integration. SCPI command compatibility enables repeatable automated procedures, while standard Web Control provides browser-based remote access without requiring a separate control application.
The USB-C power input supports operation from a compatible mobile power source, making the generator practical for temporary workspaces and field measurements where conventional bench power is less convenient.
Applications
- Analog and digital circuit development
- Amplifier and filter response testing
- Communication and modulation experiments
- Pulse and transient-response measurements
- Harmonic generation and device evaluation
- Sensor and control-signal simulation
- Electronics education and laboratory exercises
- Automated production and functional testing
- Portable testing with a compatible USB-C power source
