Rigol MHO2034 350 MHz 4-Channel Mixed Signal Oscilloscope

The RIGOL MHO2034 Mixed-Signal Oscilloscope is the 350 MHz model in the RIGOL MHO2000 Series. It is developed for engineers, technicians, electronics manufacturers, research laboratories and educational institutions that need detailed analogue measurements together with digital logic and protocol analysis.

Built on RIGOL’s Centaurus high-resolution technology platform, the MHO2034 combines four analogue channels, 16 digital channels, deep acquisition memory and advanced analysis functions within one expandable instrument.

Its 12-bit analogue-to-digital converter provides 4,096 vertical quantisation levels. This gives the oscilloscope 16 times more vertical levels than a conventional 8-bit oscilloscope, helping users identify small voltage variations, low-amplitude noise, power-supply ripple and other fine waveform details.

350 MHz Analogue Bandwidth

The MHO2034 provides 350 MHz analogue bandwidth across four input channels.

This bandwidth supports measurements involving:

• Embedded processors and microcontrollers
• FPGA-based systems
• Digital clock signals
• Switching power converters
• Industrial control electronics
• Automotive communication buses
• High-speed analogue circuits
• Communication interfaces
• Sensor and actuator systems

The specified typical rise time is approximately 1.4 ns at 50 Ω, allowing the oscilloscope to capture relatively fast waveform transitions and timing behaviour.

Four Analogue Channels and One External Trigger

The MHO2034 includes:

• Four analogue input channels
• One external trigger input
• 16 digital channels with a compatible PLA3204 logic probe

The four analogue inputs allow engineers to acquire multiple related signals within the same time-correlated measurement.

Typical applications include:

• Comparing circuit input and output
• Measuring clock, data, enable and reset signals
• Monitoring multiple power rails
• Examining gate, drain and current waveforms
• Testing multi-phase power systems
• Comparing sensor and actuator signals

The separate external trigger input allows the oscilloscope to trigger from an additional signal without occupying an analogue measurement channel.

Mixed-Signal Analysis

The MHO2034 platform includes 16 digital-channel capability. A compatible RIGOL PLA3204 logic analysis probe is required to connect digital signals.

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

This is useful for:

• Microcontroller debugging
• FPGA validation
• Parallel bus analysis
• ADC and DAC testing
• Embedded control systems
• Digital power applications
• Logic timing analysis
• Correlating analogue events with digital activity

RIGOL describes the digital channels as a standard platform capability, while the logic probe is supplied separately.

2 GSa/s Sampling on All Channels

The MHO2034 provides a maximum real-time sampling rate of 2 GSa/s on all four analogue channels.

This independent per-channel performance allows engineers to capture four related signals without reducing the maximum 2 GSa/s sampling rate when all channels are active.

High-speed sampling supports detailed analysis of:

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

The combination of 350 MHz bandwidth and 2 GSa/s per channel provides approximately five times oversampling at the oscilloscope’s rated bandwidth.

Deep Acquisition Memory

The MHO2034 provides:

• Up to 500 Mpts in half-channel operation
• Up to 250 Mpts when all four analogue channels are active

Half-channel operation refers to an acquisition configuration in which one channel from each analogue channel pair is enabled.

Deep memory allows engineers to capture longer signal sequences while maintaining a high sample rate.

It is especially useful for:

• Long serial bus acquisitions
• Embedded-software debugging
• Power-up sequence analysis
• Intermittent fault investigation
• Communication packet analysis
• Multi-cycle measurements
• Extended waveform monitoring
• Detailed waveform zooming

The memory specification should therefore be written as up to 500 Mpts, rather than 500 Mpts simultaneously available on each of the four channels.

Fast Waveform Capture

The MHO2034 provides:

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

A faster waveform capture rate reduces acquisition dead time and increases the probability of finding uncommon signal events.

This capability helps identify:

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

Fast recording is particularly useful when a fault appears only occasionally and cannot be reproduced during every acquisition.

12-Bit Vertical Resolution

The 12-bit ADC provides 4,096 amplitude levels.

This helps improve visibility during:

• Power-supply ripple measurement
• Sensor output analysis
• Low-level analogue testing
• Audio signal measurement
• Medical electronics testing
• Power integrity analysis
• Precision voltage measurement
• Small-signal troubleshooting

Compared with an 8-bit oscilloscope, the MHO2034 provides finer voltage quantisation and better separation of closely spaced amplitude values.

Up to 16-Bit High Resolution Mode

High Resolution acquisition processing can increase effective vertical resolution up to 16 bits.

This mode can help:

• Reduce visible random noise
• Improve low-frequency measurement clarity
• Reveal small waveform variations
• Improve low-level amplitude analysis
• Support precision power measurements

The available bandwidth and sample-rate performance can decrease when higher-resolution modes are selected.

Low-Noise Signal Measurement

The MHO2034 provides vertical sensitivity down to 100 μV/div.

This supports measurements involving:

• Power-rail ripple
• Low-level sensor signals
• Reference voltages
• Audio waveforms
• Analogue control signals
• Power-supply noise
• Low-amplitude embedded signals

The actual measurement noise depends on probe selection, bandwidth, vertical scale, input impedance, acquisition mode and environmental conditions.

Serial Bus Triggering and Decoding

The MHO2034 supports serial bus triggering and decoding for embedded, automotive, audio and aerospace systems.

Standard embedded protocol capabilities include:

• I2C
• SPI
• RS232/UART

Additional protocol options include:

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

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

• Incorrect addresses
• Invalid data
• Missing acknowledgements
• Timing problems
• Frame errors
• Communication interruptions
• Intermittent bus faults

Automotive, FlexRay, audio and aerospace analysis functions may require separate software licences.

Advanced Trigger Functions

The MHO2034 provides multiple trigger modes for capturing specific signal conditions.

Available trigger functions include:

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

Zone triggering allows users to draw an area directly on the waveform display and acquire waveforms that enter or avoid that region.

This visual triggering method can simplify the detection of glitches, abnormal transitions and infrequent waveform conditions.

Automatic Measurements and Analysis

The oscilloscope provides a broad set of measurement and analysis tools.

Available functions include:

• Voltage measurements
• Frequency and period measurements
• Rise and fall time
• Pulse width
• Duty cycle
• Overshoot and preshoot
• Channel delay

• Measurement statistics
• Cursor measurements
• FFT frequency analysis
• Waveform mathematics
• Histogram analysis
• Mask testing
• Pass/fail testing
• Search and navigation
• Hardware waveform recording
• Digital voltmeter
• Frequency counter

These functions allow engineers to move from waveform capture to detailed analysis without exporting every acquisition to separate software.

Search and Navigation

Search and navigation tools help users examine long memory records and locate specific waveform events.

Users can search according to conditions such as:

• Edge transitions
• Pulse widths
• Runt pulses
• Logic patterns
• Serial bus events
• Timing violations

Search results can be marked within the acquisition record, allowing engineers to move directly between abnormal events.

Typical measurements include:

• Power quality
• Switching loss
• Conduction loss
• Harmonic analysis

• Modulation analysis
• Power-device behaviour

High-voltage differential probes and current probes should be selected according to the maximum voltage, current, bandwidth and common-mode requirements.
