Rigol DHO1000U Series

The RIGOL DHO1000U Series High-Resolution Digital Oscilloscope is developed for engineers, technicians, electronics manufacturers, educational institutions and research laboratories that need accurate waveform capture and dependable day-to-day measurement performance.

The series combines 12-bit acquisition, low-noise analogue front-end performance, deep waveform memory and a large touch interface in an accessible benchtop platform. It is suitable for observing analogue signals, power rails, sensor outputs, digital timing, communication buses and intermittent circuit faults.

The DHO1000U Series includes:

• DHO1202U: 200 MHz bandwidth and two analogue channels
• DHO1204U: 200 MHz bandwidth and four analogue channels

Both models also include one external trigger input.

12-Bit High-Resolution Acquisition

The DHO1000U uses a 12-bit analogue-to-digital converter, providing 4,096 vertical quantisation levels.

Compared with a conventional 8-bit oscilloscope, 12-bit acquisition provides 16 times more vertical levels. This helps engineers distinguish smaller voltage changes and examine waveform details that may be difficult to identify on lower-resolution instruments.

The 12-bit acquisition system supports:

• Low-level signal measurement
• Power-rail ripple analysis
• Sensor output evaluation
• Noise investigation
• Small waveform variation detection
• Precision amplitude measurements
• Analogue circuit debugging
• Power electronics testing

The oscilloscope also supports up to 16-bit processing in High Resolution mode. The available bandwidth and sample rate may be reduced when higher-resolution processing is selected.

Ultra-Low Noise Performance

The DHO1000U is designed with a low-noise front end for measuring small signals more clearly.

RIGOL specifies a typical noise floor of approximately 75 μVrms at the 500 μV/div setting under its stated test conditions.

Low-noise performance is useful when measuring:

• Voltage regulator ripple
• Sensor outputs
• Audio signals
• Analogue control signals
• Low-level embedded signals
• Power-supply noise
• Reference voltages
• Small signal variations

The instrument provides vertical sensitivity from 500 μV/div to 10 V/div, helping users measure both low-level signals and larger circuit voltages.

Up to 2 GSa/s Real-Time Sampling

The DHO1000U Series provides a maximum real-time sample rate of up to 2 GSa/s.

For the DHO1204U four-channel model, the available sample rate depends on the active-channel configuration:

• 2 GSa/s with one analogue channel active
• 1 GSa/s in half-channel operation
• 500 MSa/s with all four analogue channels active

High-speed sampling helps preserve waveform detail when examining:

• Digital clock signals
• Short pulses
• Signal transitions
• Switching waveforms
• Communication data
• Timing relationships
• Overshoot and ringing
• Intermittent glitches

The DHO1202U provides up to 2 GSa/s in single-channel operation and 1 GSa/s when both analogue channels are active.

UltraAcquire Waveform Capture

The DHO1000U supports waveform capture rates of:

• Up to 30,000 wfms/s in Vector mode
• Up to 500,000 wfms/s in UltraAcquire mode

UltraAcquire reduces acquisition dead time and improves the probability of detecting uncommon waveform abnormalities.

It is useful for identifying:

• Rare glitches
• Runt pulses
• Signal dropouts
• Timing violations
• Intermittent noise
• Unstable clock signals
• Abnormal transitions
• Occasional communication faults

The DHO1000U UltraAcquire rate should not be confused with the 1,500,000 wfms/s rate of the standard DHO1000 Series.

Deep Acquisition Memory

The DHO1000U provides 25 Mpts standard maximum memory in single-channel operation, with an optional upgrade to 50 Mpts.

Memory allocation depends on the number of active channels.

For the DHO1204U:

• 25 Mpts standard in single-channel mode
• 10 Mpts standard in half-channel mode
• 1 Mpts standard with all four channels active
• 50 Mpts optional in single-channel mode
• 25 Mpts optional in half-channel mode
• 10 Mpts optional with all four channels active

Deep memory allows engineers to capture longer signal records while maintaining useful sampling detail.

Typical applications include:

• Serial bus debugging
• Long communication packets
• Power-up sequence testing
• Intermittent fault analysis
• Extended timing measurements
• Embedded-system debugging
• Long-duration waveform observation
• Detailed waveform zooming

Memory depth should therefore be described as up to 50 Mpts optional, not 50 Mpts simultaneously on every channel.

Hardware Waveform Recording

The DHO1000U supports hardware waveform recording and playback of up to 500,000 frames.

Waveform recording allows users to:

• Capture sequences of signal events
• Replay recorded waveforms
• Review individual frames
• Compare normal and abnormal behaviour
• Investigate intermittent faults
• Analyse signal changes after testing
• Perform unattended monitoring

The system can also detect glitches as narrow as approximately 2 ns in Peak Detect mode under supported conditions.

Automatic Measurements

The oscilloscope supports common automatic waveform measurements for voltage, time, frequency and pulse analysis.

Typical measurements include:

• Frequency
• Period
• Peak-to-peak voltage
• Maximum voltage
• Minimum voltage
• RMS voltage
• Average voltage
• Rise time
• Fall time
• Positive pulse width
• Negative pulse width
• Duty cycle
• Overshoot
• Preshoot
• Phase
• Channel-to-channel delay

Measurement statistics help users evaluate signal consistency over repeated acquisitions.

•  

Serial Bus Triggering and Decoding

The DHO1000U supports serial bus analysis for embedded and automotive applications.

Supported protocols include:

• RS232/UART
• I2C
• SPI
• CAN
• LIN
• Parallel bus

Serial decoding displays protocol information alongside the electrical waveform, helping users identify:

• Incorrect addresses
• Invalid data
• Missing acknowledgements
• Timing errors
• Bus interruptions
• Communication faults

Protocol availability and included licences should be confirmed for the supplied regional configuration.

Advanced Trigger Functions

The oscilloscope provides trigger functions for isolating specific waveform conditions.

Trigger types include:

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

These trigger functions help engineers capture specific events rather than reviewing large numbers of normal acquisitions.

Mask and Pass/Fail Testing

Users can create acceptable waveform boundaries and check whether subsequent acquisitions remain within those limits.

This function is useful for:

• Production validation
• Quality control
• Long-duration monitoring
• Component comparison
• Design verification
• Repetitive laboratory testing
•  

10.1-Inch HD Touchscreen
