Rigol DG800 Pro Series

The RIGOL DG800 Pro Series Function/Arbitrary Waveform Generator is designed for engineers, technicians, research laboratories, educational institutions and electronics manufacturers requiring a flexible source for standard, pulse, modulated and arbitrary signals.

The series combines several test functions in one compact instrument:

• Function generator
• Arbitrary waveform generator
• Pulse generator
• Noise generator
• Harmonic generator
• Analog and digital modulator
• Sequence generator
• Frequency sweep generator
• Burst generator
• Frequency counter

The DG800 Pro is suitable for stimulating circuits, simulating sensor outputs, testing communication systems, evaluating filters and amplifiers, generating clock signals and reproducing application-specific waveform conditions.

The RIGOL DG800 Pro Series includes:

• DG821 Pro: 25 MHz, one output channel
• DG822 Pro: 25 MHz, two output channels
• DG852 Pro: 50 MHz, two output channels

All three models provide:

• 625 MSa/s maximum sampling rate
• 16-bit vertical resolution
• 2 Mpts standard arbitrary waveform memory per channel
• Optional 8 Mpts memory per channel
• 7-inch colour touchscreen
• USB and LAN connectivity
• Web Control
• USB Type-C power input
• Independent external frequency-counter input

The single-channel DG821 Pro can be upgraded to two-channel operation using the applicable channel-upgrade option.

Standard Waveform Generation

The DG800 Pro Series supports common waveforms required for laboratory and electronic test applications.

Available continuous waveform types include:

• Sine
• Square
• Ramp
• Pulse
• Noise
• Arbitrary
• Harmonic

These waveforms can be used for:

• Amplifier testing
• Filter evaluation
• Clock generation
• Sensor simulation
• Analog circuit testing
• Digital circuit debugging
• Control-system stimulation
• Communication experiments
•  

Arbitrary Waveform Generation

The series supports arbitrary waveform generation with a maximum sample rate of 625 MSa/s and 16-bit vertical resolution.

Standard arbitrary waveform memory is 2 Mpts per channel, while the optional memory upgrade increases capacity to 8 Mpts per channel.

Arbitrary waveform generation is useful for reproducing:

• Sensor outputs
• Biomedical signals
• Communication patterns
• Power disturbances
• Irregular pulses
• Recorded signal conditions
• Automotive waveforms
• Custom engineering test signals

The arbitrary waveform length can be configured from 32 points per channel to the installed memory limit.

SiFi II Signal Fidelity Technology

The DG800 Pro uses RIGOL SiFi II technology for point-by-point arbitrary waveform generation.

This approach is designed to:

• Preserve the original waveform point sequence
• Reduce skipped or repeated waveform points
• Improve arbitrary waveform fidelity
• Reduce signal jitter
• Support precisely adjustable sample rates
• Improve reproduction of complex waveform shapes

RIGOL specifies output jitter as low as approximately 200 ps RMS under applicable conditions.

Dual-Channel Signal Generation

The DG822 Pro and DG852 Pro include two output channels. The DG821 Pro provides one channel as standard and supports an optional second-channel upgrade.

Dual-channel operation is suitable for:

• Simultaneous generation of two signals
• Phase-related waveform testing
• Differential circuit stimulation
• Clock and data simulation
• Reference and excitation signal generation
• Two-stage circuit testing
• Dual-input amplifier testing
• I/Q signal simulation

Each channel can be configured with its own frequency, amplitude, offset, phase, waveform and modulation settings.

Frequency Capability

The maximum sine-wave frequency depends on the selected model:

• DG821 Pro: 25 MHz
• DG822 Pro: 25 MHz
• DG852 Pro: 50 MHz

Waveform-specific frequency limits differ from the maximum sine-wave rating.

For the DG852 Pro:

• Sine: up to 50 MHz
• Square: up to 40 MHz
• Ramp: up to 1 MHz
• Pulse: up to 25 MHz
• Arbitrary: up to 15 MHz
• Harmonic: up to 25 MHz

For the DG821 Pro and DG822 Pro:

• Sine: up to 25 MHz
• Square: up to 20 MHz
• Ramp: up to 1 MHz
• Pulse: up to 10 MHz
• Arbitrary: up to 10 MHz
• Harmonic: up to 10 MHz

The maximum output frequency should therefore be specified according to the selected waveform type rather than applied to every signal function.

Sequence Generation

The DG800 Pro supports advanced sequence generation for combining multiple waveform events into one automated test profile.

The sequence function supports:

• Up to 64 waveform entries
• Up to 256 repetitions
• Sample rates from 1 μSa/s to 312.5 MSa/s
• Normal, step and interpolation filter modes
• Multiple arbitrary waveforms within one sequence
• Seamless execution of programmed test cases

Sequence generation is useful for:

• Automotive signal simulation
• Power-state transition testing
• Sensor-output sequences
• Communication pattern generation
• Production validation
• Fault-condition reproduction
• Multi-stage stimulus generation

A loop setting of zero can be used for continuous sequence repetition, depending on the configured sequence behaviour.

Modulation Functions

The DG800 Pro supports multiple analog and digital modulation types:

• AM
• FM
• PM
• SUM
• ASK
• FSK
• PSK
• PWM

These modulation capabilities support:

• Communication-system education
• Receiver testing
• Carrier modulation experiments
• Digital communication testing
• Motor-control development
• Switching power-supply testing
• Modulation and demodulation verification
•  

Sweep Function

The sweep function automatically changes the output frequency across a configured range.

Supported sweep types include:

• Linear sweep
• Logarithmic sweep
• Step sweep

Sweep generation is useful for:

• Filter response testing
• Amplifier bandwidth measurement
• Resonance detection
• Audio-system testing
• Frequency-response analysis

Pulse Generation

The DG852 Pro supports pulse output up to 25 MHz, while the DG821 Pro and DG822 Pro support pulse output up to 10 MHz.

The DG852 Pro provides waveform rise times as low as approximately 3 ns under specified conditions.

Pulse generation supports:

• Adjustable pulse width
• Adjustable rise time
• Adjustable fall time
• Duty-cycle control
• Delay control
• Triggered pulse generation

This makes the generator suitable for digital circuit testing, timing validation and switching-system analysis.

The built-in harmonic generator supports harmonics up to the 20th order.

Users can configure harmonic components for:

• Filter testing
• Amplifier linearity testing
• Distortion simulation

•  

Output Amplitude

The DG800 Pro provides a wide output-amplitude range.

Into a 50 Ω load:

• 1 mVpp to 10 Vpp

Into high impedance:

• 2 mVpp to 20 Vpp

Maximum combined AC and DC output is:

• ±5 Vpk into 50 Ω
• ±10 Vpk into high impedance

The output impedance is nominally 50 Ω.

Independent Frequency Counter

The series includes a dedicated external frequency-counter input with bandwidth up to 500 MHz.

The seven-digit frequency counter can measure:

• Frequency
• Period
• Duty cycle
• Positive pulse width
• Negative pulse width

It also supports statistical analysis of measurement results.

The frequency-counter input is separate from the waveform output channels, allowing an external signal to be measured while the generator produces test signals.

7-Inch Colour Touchscreen

The DG800 Pro includes a 7-inch colour touchscreen with 1024 × 600 resolution.

The display supports:

• Simultaneous dual-channel waveform viewing
• Touch-based parameter adjustment
• Waveform preview
• Modulation configuration
• Sequence editing
• File management
• Counter measurement results
• System and connectivity settings

The larger display improves visibility when configuring two channels or editing complex arbitrary waveform sequences.

The required power specification is:

• 15 V
• 3 A
• 45 W

In addition to the supplied power adapter, a compatible USB PD power source or power bank can be used when it supports the required output.

This enables:

• Portable field testing

• Reduced bench cable requirements
• Use in mobile engineering setups
•  

Compact and Portable Design

The DG800 Pro measures approximately:

• 266 mm wide
