Rigol MHO2024 200 MHz 4-Channel Mixed Signal Oscilloscope

The RIGOL MHO2024 Mixed-Signal Oscilloscope is part of the MHO2000 Series of high-resolution oscilloscopes. It is designed for engineers, technicians, research laboratories, educational institutions and electronics manufacturers that need accurate analogue measurements together with digital and protocol analysis.

Built on RIGOL’s Centaurus high-resolution technology platform, the MHO2024 uses a 12-bit analogue-to-digital converter to provide 4,096 vertical quantisation levels. This delivers 16 times more amplitude levels than a conventional 8-bit oscilloscope, helping users observe small signal variations, low-level ripple and waveform details more clearly.

The MHO2024 provides:

• 200 MHz analogue bandwidth
• Four analogue input channels
• One external trigger input
• 16 digital channels with a compatible logic probe
• Up to 2 GSa/s real-time sampling
• Up to 500 Mpts memory depth
• Up to 1,000,000 wfms/s waveform capture
• 12-bit hardware vertical resolution
• Up to 16-bit processing in High Resolution mode
• 10.1-inch capacitive multi-touch display

The oscilloscope integrates analogue acquisition, digital logic analysis, protocol decoding, signal generation and advanced application tools within one expandable platform.

High-Resolution 12-Bit Acquisition

The MHO2024 uses a 12-bit analogue-to-digital converter, providing 4,096 discrete amplitude levels.

This high-resolution architecture helps engineers analyse:

• Power-supply ripple
• Sensor outputs
• Low-amplitude analogue signals
• Reference voltages
• Audio waveforms
• Power electronic signals
• Medical electronic circuits
• Small variations on larger waveforms

Compared with an 8-bit oscilloscope, the MHO2024 provides improved vertical detail and makes small waveform changes easier to distinguish.

High Resolution acquisition modes can further improve effective resolution up to 16 bits. Available bandwidth and sampling performance may be reduced when higher-resolution processing is selected.

200 MHz Analogue Bandwidth

The MHO2024 provides 200 MHz analogue bandwidth across four channels.

This bandwidth is suitable for:

• Embedded electronic systems
• Microcontroller signals
• Digital clocks
• Industrial control circuits
• Automotive communication buses
• Switching power supplies
• Analogue circuit testing
• Communication interface debugging

The 200 MHz bandwidth provides a typical 10% to 90% rise-time capability of approximately 1.75 ns under the specified measurement conditions.

Four Analogue Channels

The four analogue inputs allow engineers to observe several related signals in one time-correlated acquisition.

Typical four-channel measurements include:

• Input and output signals
• Clock, data and enable lines
• Multiple power rails
• Gate and drain waveforms
• Three-phase or multi-phase control signals
• Sensor and actuator signals
• Communication transmit and receive lines

A separate external trigger input is also available for triggering from a signal that does not need to occupy an analogue measurement channel.

Mixed-Signal Analysis

The MHO2024 supports 16 digital channels for mixed-signal debugging.

A compatible PLA3204 logic analysis probe is required to connect digital signals to the oscilloscope.

Mixed-signal analysis allows users to display analogue and digital signals on the same time base. It is useful for:

• Microcontroller debugging
• FPGA testing
• Parallel bus analysis
• ADC and DAC validation
• Embedded control systems
• Digital power systems
• Timing relationship analysis
• Analogue and digital event correlation

The digital-channel function is part of the MHO2000 platform, while the physical logic probe is selected separately.

Up to 2 GSa/s Real-Time Sampling

The MHO2024 supports a maximum real-time sampling rate of up to 2 GSa/s.

High-speed sampling helps preserve waveform detail when analysing:

• Fast edges
• Short pulses
• Clock signals
• Serial communication
• Switching transitions
• Overshoot and ringing
• Intermittent glitches
• Timing errors

The available sample rate may depend on the number of enabled channels and acquisition configuration.

Up to 500 Mpts Memory Depth

Deep acquisition memory of up to 500 Mpts allows engineers to record long signal sequences while retaining detailed sample information.

Deep memory is useful for:

• Long protocol captures
• Embedded-software debugging
• Power-up sequence analysis
• Intermittent fault investigation
• Long-duration signal monitoring
• Communication packet analysis
• Detailed waveform zooming
• Multi-cycle measurements

The available memory can depend on the number of active channels and selected acquisition mode.

Fast Waveform Capture

The MHO2024 provides a maximum waveform capture rate of up to 1,000,000 waveforms per second in fast acquisition mode.

A high capture rate reduces acquisition dead time and improves the probability of detecting:

• Rare glitches
• Runt pulses
• Signal dropouts
• Timing violations
• Intermittent noise
• Abnormal waveform transitions
• Unstable clock signals
• Occasional protocol errors
•  

Waveform Recording and Playback

Hardware waveform recording allows a sequence of triggered waveform events to be stored and reviewed.

Users can:

• Record intermittent events
• Replay captured waveforms
• Review individual frames
• Compare normal and abnormal behaviour
• Search for specific waveform conditions
• Analyse events after a long test

This is useful for unattended testing, reliability analysis and debugging faults that do not occur during every acquisition.

Low-Noise Signal Measurement

The MHO2024 provides vertical sensitivity down to 200 μV/div, helping engineers analyse low-level signals and small ripple components.

Low-noise measurement applications include:

• Power-rail ripple
• Sensor outputs
• Audio signals
• Reference voltages
• Analogue control signals
• Low-level embedded signals
• Power-supply noise

Actual noise performance depends on bandwidth, probe selection, vertical range, sample rate and acquisition settings.

Serial Bus Triggering and Decoding

The MHO2024 supports serial protocol triggering and decoding for embedded, automotive, audio and aerospace applications.

Standard embedded protocol functions include:

• I2C
• SPI
• RS232/UART

Additional protocol options can include:

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

Decoded data is displayed together with the electrical waveform, helping engineers identify:

• Incorrect addresses
• Invalid data
• Missing acknowledgements
• Timing problems
• Frame errors
• Bus interruptions
• Intermittent communication faults

Advanced protocol availability depends on the installed software licences.
