•  

Available Models

The DG70000 Series includes:

• DG70002: Two output channels
• DG70004: Four output channels

Both models support:

• Maximum output frequency up to 5 GHz
• Adjustable sample rate up to 12 GSa/s
• 16-bit vertical resolution
• Up to 1.5 Gpts waveform memory per channel
• Long sequence generation
• IQ modulation and digital upconversion
• Frequency hopping
• 15.6-inch 2K touchscreen
• High-speed data and remote-control interfaces

The DG70004 is the preferred model when four synchronised channels are required for multi-signal simulation, phased testing, communication research or complex system validation.

High-Frequency Signal Generation

The DG70000 Series provides output frequencies from DC up to 5 GHz, allowing the generator to cover baseband, intermediate-frequency and selected RF applications.

The wide output range supports:

• Clock signal generation
• High-speed serial test patterns
• Intermediate-frequency simulation
• RF carrier generation
• Receiver sensitivity testing
• Amplifier and filter evaluation
• Radar waveform generation
• Communication-system testing

The 5 GHz figure refers to the maximum generated output frequency. Arbitrary-waveform bandwidth and modulation bandwidth should be evaluated separately according to the operating mode.

High-Speed Sampling

The DG70000 provides a native arbitrary-waveform sample rate up to 5 GSa/s and supports sample rates up to 12 GSa/s through interpolation and digital processing.

The available sample-rate range allows engineers to optimise the generator for both slow and high-speed signals.

Benefits include:

• Accurate waveform timing
• Improved reproduction of fast transitions
• Fine control of pulse position
• High-speed serial pattern generation
• Wideband modulation
• Reduced waveform distortion
• Improved timing resolution

RIGOL specifies adjustable sampling from 100 Sa/s to 12 GSa/s, depending on the selected waveform mode and processing configuration.

16-Bit Vertical Resolution

The DG70000 Series uses 16-bit vertical resolution, providing up to 65,536 amplitude levels.

Higher vertical resolution supports:

• Fine amplitude control
• Detailed arbitrary-waveform reproduction
• Low-level signal generation
• Large dynamic-range testing
• Reduced quantisation steps
• Improved modulation accuracy
• Precise impairment simulation

This is particularly useful when small signal variations must be reproduced on top of a larger waveform.

Deep Waveform Memory

The series supports waveform memory up to 1.5 Gpts per channel.

Deep memory allows users to generate long-duration and highly detailed waveform records without repeatedly loading new data.

Applications include:

• Long communication frames
• Extended radar sequences
• Frequency-hopping patterns
• Complex electromagnetic simulations
• Recorded waveform reproduction
• High-speed digital patterns
• Multi-event test sequences
• Long-duration scientific signals

RIGOL also lists up to 4 Gpts total waveform-table capacity in supported configurations, depending on channel use and memory allocation.

Advanced Sequence Generation

The sequence editor supports up to 16,384 waveform segments.

Each sequence can combine multiple waveform files, repeat counts, jumps and trigger conditions into one automated test profile.

Sequence generation is useful for:

• Multi-stage communication tests
• Automotive operating-condition simulation
• Radar pulse sequences
• Receiver stress testing
• Frequency-hopping signals
• Fault-condition reproduction
• Power-state transition testing
• Automated product validation

Long waveform memory and sequence control allow complex test conditions to be reproduced consistently.

IQ Modulation and Digital Upconversion

The DG70000 supports wideband IQ modulation and digital upconversion.

The platform provides modulation bandwidth up to 1.5 GHz, allowing the generation of modern wideband communication signals.

Supported applications include:

• 256QAM
• 1024QAM
• Wideband IQ waveform generation
• Communication receiver testing
• Baseband-to-RF conversion
• Wireless-standard simulation
• Error-vector-magnitude testing
• Modulation quality evaluation

Users can create baseband IQ waveforms and digitally shift them to a selected carrier frequency without requiring a separate external IQ modulator.

Frequency-Hopping Generation

The built-in frequency-hopping function supports hop intervals as low as approximately 128 ns.

Fast frequency hopping is useful for:

• Frequency-agile communication systems
• Radar testing
• Electronic countermeasure research
• Spread-spectrum development
• Interference-resilience testing
• Receiver tracking evaluation
• Complex electromagnetic simulation

Frequency, amplitude and timing parameters can be configured to reproduce changing RF environments.

High-Speed Interface Receiver Testing

The DG70000 can generate test patterns and controlled signal impairments for receiver validation.

Potential test applications include:

• High-speed serial receiver testing
• Clock and data recovery evaluation
• Jitter tolerance testing
• Eye-opening margin testing
• Receiver sensitivity analysis
• Pattern-dependent fault investigation
• Worst-case signal simulation

Suitable optional software and high-speed connection accessories may be required for specific serial standards.

Complex Electromagnetic Environment Simulation

Multiple DG70000 channels can be used to generate dense, dynamic and repeatable signal environments.

This allows engineers to evaluate:

• Receiver coexistence
• Interference susceptibility
• Anti-interference performance
• System behaviour under multiple carriers
• Frequency-hopping response
• Communication performance in congested spectrum
• Radar and electronic system performance

Repeatable waveform generation helps laboratories compare system performance under consistent test conditions.

High Signal Purity
