RIGOL DHO5000 Series

The RIGOL MHO/DHO5000 Series is designed for engineers who need to measure several analogue, digital and power-related signals simultaneously without combining multiple oscilloscopes.

Developed on RIGOL’s Centaurus high-resolution technology platform, the series combines a 12-bit acquisition system, up to eight analogue input channels, deep memory, fast waveform recording and advanced analysis functions in a compact benchtop or rack-mountable enclosure.

The family is divided into two product groups:

DHO5000 Digital Oscilloscopes

DHO5000 models provide four or eight analogue channels:

• DHO5054
• DHO5104
• DHO5058
• DHO5108

MHO5000 Mixed-Signal Oscilloscopes

MHO5000 models combine four or six analogue channels with 16 digital channels:

• MHO5054
• MHO5104
• MHO5056
• MHO5106

The 16 digital channels require compatible PLA3204 logic analyser probes. The MHO four-channel models also support an optional two-channel 50 MHz arbitrary waveform and function generator.

Eight-Model Product Range

This lineup allows laboratories to select the required combination of bandwidth, analogue-channel density and digital-debugging capability without paying for unnecessary functions.

12-Bit High-Resolution Acquisition

Every MHO/DHO5000 model uses a 12-bit analogue-to-digital converter.

A 12-bit ADC provides 4,096 vertical quantisation levels, compared with 256 levels on a conventional 8-bit oscilloscope. This gives the instrument 16 times more vertical levels for representing waveform amplitude.

The additional resolution is useful for observing:

• Power-rail ripple
• Small voltage variations
• Switching noise
• Sensor outputs
• Reference voltages
• Low-amplitude control signals
• Power-semiconductor behaviour
• Analogue distortion
• Overshoot and undershoot

High Resolution processing can increase effective resolution to as much as 16 bits. Available bandwidth and sample-rate performance may be reduced when higher-resolution acquisition modes are selected.

500 MHz and 1 GHz Bandwidth Options

The series provides two analogue-bandwidth classes:

• 500 MHz models
• 1 GHz models

At 50 Ω input impedance, the DHO5104, DHO5108, MHO5104 and MHO5106 provide bandwidth up to 1 GHz under the supported channel configuration.

At 1 MΩ input impedance, maximum analogue bandwidth is 500 MHz.

The bandwidth options support applications such as:

• Fast digital clock analysis
• FPGA and processor debugging
• Power-semiconductor switching tests
• SiC and GaN device evaluation
• Motor-drive control analysis
• Automotive electronics
• Communication interface testing
• Embedded-system validation
• Signal-integrity troubleshooting

For the 1 GHz models, RIGOL specifies calculated rise time of approximately 400 ps in single- and half-channel operation and approximately 440 ps in full-channel operation. The 500 MHz models have a typical calculated rise time of approximately 750 ps.

Four, Six or Eight Analogue Channels

The main advantage of the MHO/DHO5000 Series is its high analogue-channel density.

Users can select:

• Four analogue channels for general electronics and mixed-signal debugging
• Six analogue channels for multi-rail, embedded and power-system measurements
• Eight analogue channels for complex power, motor-drive and semiconductor testing

Multiple channels help engineers examine related signals in one time-correlated acquisition.

Typical examples include:

• Three phase voltages and three phase currents
• Gate, drain and current waveforms
• Input, output and feedback signals
• Multiple supply rails
• Enable, reset and power-good signals
• Motor phase and control signals
• Processor clocks and communication buses
• Power-up and shutdown sequences

Using one multi-channel instrument avoids timing uncertainty caused by combining independent oscilloscopes.

Up to 4 GSa/s Real-Time Sampling

The maximum sample rate depends on the selected model and active-channel configuration.

Four-Channel DHO Models

The DHO5054 and DHO5104 provide up to 4 GSa/s in single-, half- and full-channel configurations.

Six-Channel MHO Models

The MHO5056 and MHO5106 provide:

• 4 GSa/s in single-channel mode
• 4 GSa/s in half-channel mode
• 2 GSa/s in full-channel mode

Eight-Channel DHO Models

The DHO5058 and DHO5108 provide:

• 4 GSa/s in single-channel mode
• 4 GSa/s in half-channel mode
• 2 GSa/s when all eight channels are active

The MHO5054 and MHO5104 also provide 4 GSa/s in single- and half-channel operation and 2 GSa/s in full-channel mode according to the current series datasheet.

High sampling rates improve signal reconstruction during:

• Fast switching transitions
• Narrow pulse measurement
• Digital clock testing
• Overshoot and ringing analysis
• Serial communication debugging
• Timing measurements
• Intermittent glitch detection
•  

Up to 500 Mpts Acquisition Memory

The MHO/DHO5000 Series provides deep acquisition memory for capturing long signal records while maintaining a useful sample rate.

Maximum memory allocation is:

• 500 Mpts in single-channel mode
• 500 Mpts in half-channel mode
• 250 Mpts in full-channel mode

RIGOL defines half-channel operation as enabling alternating channels from each acquisition group. The exact channel combinations differ according to the four-, six- or eight-channel instrument configuration.

Deep memory is useful for:

• Long startup sequences
• Embedded-software debugging
• Power-sequencing analysis
• Extended serial communication captures
• Motor-control behaviour
• Intermittent faults
• Multi-cycle power measurements
• Detailed waveform zooming
• Long semiconductor switching records

The product should therefore be described as providing up to 500 Mpts, rather than 500 Mpts independently on every active channel.

Up to 1,000,000 wfms/s Capture Rate

The MHO/DHO5000 Series provides two principal waveform-capture rates:

• Up to 200,000 wfms/s in Vector mode
• Up to 1,000,000 wfms/s in Record mode

Fast acquisition reduces oscilloscope dead time and improves the probability of capturing uncommon signal events.

It helps engineers locate:

• Rare glitches
• Runt pulses
• Timing violations
• Intermittent noise
• Signal dropouts
• Switching abnormalities
• Unstable clock behaviour
• Occasional protocol faults

The oscilloscope also supports recording of up to 500,000 waveform frames for playback and post-test investigation. Peak Detect acquisition can identify glitches as narrow as approximately 500 ps under supported conditions.

16 Digital Channels on MHO Models

The MHO5054, MHO5104, MHO5056 and MHO5106 support 16 digital channels.

Digital inputs require compatible PLA3204 four-channel logic analyser probes. Four PLA3204 probes are required to access all 16 digital channels.

Mixed-signal analysis allows analogue and digital signals to be displayed on the same time base.

This is useful for:

• Microcontroller debugging
• FPGA validation
• Parallel bus analysis
• ADC and DAC testing
• State-machine troubleshooting
• Digital power control
• Robotics and automation
• Embedded-system development
• Correlating analogue faults with digital events

The DHO5054, DHO5104, DHO5058 and DHO5108 do not provide digital channels.

Serial Bus Triggering and Decoding

The series supports embedded serial bus analysis for commonly used digital interfaces.

Standard embedded decoding includes:

• I²C
• SPI
• RS232/UART

Additional application options can add:

• CAN
• CAN FD
• LIN
• FlexRay
• SENT
• I²S
• MIL-STD-1553B

Decoded communication data can be displayed alongside the electrical waveform, helping engineers identify:

• Incorrect addresses
• Invalid data
• Missing acknowledgements
• Frame errors
• Timing violations
• Bus interruptions
• Intermittent communication failures

Protocol availability depends on the model and installed application licences.

Advanced Trigger Functions

The MHO/DHO5000 Series provides trigger functions for isolating specific signal conditions.

Trigger types include:

• Edge
• Pulse width
• Slope
• Video
• Pattern
• Duration
• Timeout
• Runt
• Window
• Delay
• Setup and hold
• Nth edge
• Zone trigger
• Serial bus trigger

Zone triggering allows engineers to define a region directly on the waveform display and capture signals that enter or avoid that area.

This visual trigger method is useful when an abnormal waveform is easy to recognise but difficult to describe using conventional trigger settings.

Optional Dual-Channel 50 MHz AFG

An optional function and arbitrary waveform generator is available only for:

• MHO5054
• MHO5104

The integrated generator provides:

• Two output channels
• 1 GSa/s sampling
• 16-bit vertical resolution
• Maximum sine-wave frequency of 50 MHz
• 16 kpts arbitrary waveform memory
• Approximately 200 ps channel synchronisation accuracy

Available output waveforms include:

• Sine
• Square
• Pulse
• Ramp
• Noise
• DC
• Sinc
• Exponential rise
• Exponential fall
• ECG
• Gaussian
• Lorentz
• Haversine

The AFG is not available on the six-channel MHO models or the DHO models.

Bode Plot Analysis

Bode plot analysis is standard on the MHO5054 and MHO5104 platform, but signal generation requires the applicable AFG configuration.

The function supports:

• Gain measurement
• Phase measurement
• Filter frequency response
• Amplifier analysis
• Power-supply control-loop testing
• Crossover-frequency identification
• Gain-margin evaluation
• Phase-margin evaluation

The supported Bode sweep extends from 100 Hz to 30 MHz with 10 to 100 points per decade.

Power Analysis

Optional power-analysis software supports measurements for power supplies, inverters, motor drives and semiconductor switching devices.

Typical applications include:

• Power quality
• Switching loss
• Conduction loss
• Harmonic analysis
• Inrush current
• Output ripple
• Safe operating area
• Modulation analysis
• Converter efficiency
• Device turn-on and turn-off behaviour

Power measurements should be performed with probes selected according to the required voltage, current, bandwidth, isolation and common-mode range.

Compatible accessories include:

• High-voltage differential probes
• Optical-isolated probes
• AC/DC current probes
• Active single-ended probes
• Active differential probes
•  

Power Sequencing

Four-, six- and eight-channel configurations are particularly useful for checking the startup and shutdown order of multiple power rails.

Engineers can simultaneously monitor:

• Input voltage
• Output rails
• Enable signals
• Reset signals
• Power-good signals
• Load current
• Control signals
• Fault outputs

Deep memory preserves the full startup sequence, while search and measurement functions help locate timing errors.

Three-Phase Motor and Inverter Testing

Eight-channel DHO5000 models are suitable for motor-drive and inverter analysis because they can capture multiple phase voltages, currents and control signals simultaneously.

Typical measurements include:

• Three phase voltages
• Three phase currents
• Gate-drive signals
• DC-link voltage
• Rotor or position signals
• PWM timing
• Phase imbalance
• Switching behaviour

The higher channel count reduces the need to repeat tests with different probe placements.

SiC and GaN Power-Semiconductor Testing

The 1 GHz models can support detailed observation of fast switching behaviour in silicon carbide and gallium nitride power systems.

Applications include:

• Double-pulse testing
• Switching-loss measurement
• Gate-voltage analysis
• Drain or collector waveform analysis
• Overshoot and ringing measurement
• Dead-time verification
• Device timing comparison
• Safe operating area analysis

High-bandwidth, high-voltage differential or optical-isolated probes are required for accurate measurements of fast switching nodes.

Battery operation is useful for:

• Field diagnostics
• Vehicle-mounted testing
• Measurements without nearby AC power
• Temporary industrial installations
• Portable research work
• Noise-sensitive test environments

The battery holder is an optional accessory and should not be described as standard equipment. Battery type, operating duration and regional availability should be confirmed before ordering.
