Rigol DHO1000 Series

The RIGOL DHO1000 Series Digital Oscilloscope is developed for engineers, technicians, electronics manufacturers, educational institutions and research laboratories that require accurate waveform capture and dependable everyday measurement performance.

The series combines a 12-bit analogue-to-digital converter, low-noise front end, deep acquisition memory, fast waveform capture and a large touch interface. It is suitable for measuring analogue circuits, digital timing, sensor outputs, power rails, serial communication buses and intermittent signal faults.

Available Models

The DHO1000 Series includes six models:

• DHO1072: 70 MHz bandwidth and two analogue channels
• DHO1074: 70 MHz bandwidth and four analogue channels
• DHO1102: 100 MHz bandwidth and two analogue channels
• DHO1104: 100 MHz bandwidth and four analogue channels
• DHO1202: 200 MHz bandwidth and two analogue channels
• DHO1204: 200 MHz bandwidth and four analogue channels

Every model also includes one external trigger input. All models provide 12-bit vertical resolution, up to 2 GSa/s sampling and UltraAcquire waveform capture.

12-Bit High-Resolution Acquisition

The DHO1000 uses a 12-bit analogue-to-digital converter with 4,096 vertical quantisation levels.

A conventional 8-bit oscilloscope provides 256 levels. The 12-bit architecture therefore provides 16 times more vertical levels, helping engineers observe smaller voltage changes and separate closely spaced signal amplitudes.

This is useful for:

• Power-rail ripple measurement
• Sensor signal analysis
• Low-level analogue testing
• Reference-voltage validation
• Noise investigation
• Audio signal testing
• Power electronics
• Precision amplitude measurement

High Resolution mode can increase effective processing resolution to as much as 16 bits, although bandwidth and sample-rate performance may be reduced in higher-resolution modes.

Low-Noise Signal Measurement

The DHO1000 uses a low-noise analogue front end and provides vertical sensitivity from 500 μV/div to 10 V/div.

At 500 μV/div, RIGOL specifies typical noise-floor values of approximately:

• 62 μVrms for 70 MHz models
• 66 μVrms for 100 MHz models
• 75 μVrms for 200 MHz models

These values depend on acquisition settings, bandwidth, sample rate, memory depth and time base.

The low-noise input system supports measurements such as:

• Voltage regulator ripple
• Power-supply noise
• Sensor output variation
• Low-amplitude control signals
• Audio signals
• Analogue reference voltages
• Small embedded-system signals
•  

Up to 2 GSa/s Real-Time Sampling

The DHO1000 provides a maximum real-time sample rate of up to 2 GSa/s.

For two-channel models:

• 2 GSa/s with one channel active
• 1 GSa/s with both channels active

For four-channel models:

• 2 GSa/s with one channel active
• 1 GSa/s in half-channel mode
• 500 MSa/s with three or four channels active

The sample rate depends on the number of enabled channels because acquisition resources are shared across channel groups.

High-speed sampling supports detailed observation of:

• Digital clock signals
• Pulse edges
• Switching waveforms
• Overshoot and ringing
• Communication data
• Timing relationships
• Intermittent glitches
• Short-duration events
•  

UltraAcquire Waveform Capture

The DHO1000 supports:

• Up to 50,000 wfms/s in Vector mode
• Up to 1,500,000 wfms/s in UltraAcquire mode

UltraAcquire is a time-lapse acquisition mode designed to reduce dead time and improve the probability of capturing uncommon signal events.

It is useful for detecting:

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

Deep Acquisition Memory

The DHO1000 provides 50 Mpts standard maximum memory, with an optional upgrade to 100 Mpts.

Memory allocation depends on the model and active-channel configuration.

For two-channel models:

• 50 Mpts standard with one channel active
• 25 Mpts standard with both channels active
• 100 Mpts optional with one channel active
• 50 Mpts optional with both channels active

For four-channel models:

• 50 Mpts standard with one channel active
• 25 Mpts standard in half-channel mode
• 12.5 Mpts standard with three or four channels active
• 100 Mpts optional with one channel active
• 50 Mpts optional in half-channel mode
• 25 Mpts optional with three or four channels active

The product page should therefore state up to 100 Mpts optional, rather than 100 Mpts available simultaneously on every channel.

Deep memory is useful for:

• Long serial bus captures
• Power-up sequence analysis
• Communication packet testing
• Intermittent fault investigation
• Embedded-system debugging
• Long-duration waveform recording
• Detailed waveform zooming
•  

Hardware Waveform Recording

The DHO1000 supports hardware waveform recording and playback of up to 500,000 frames.

Waveform recording allows engineers to:

• Capture a sequence of signal events
• Replay acquired waveforms
• Review individual frames
• Compare normal and abnormal behaviour
• Locate intermittent faults
• Analyse changes after a long test
• Perform unattended monitoring

Peak Detect mode can capture glitches as narrow as approximately 2 ns under supported conditions.

Automatic Measurements

The oscilloscope supports 41 automatic waveform measurements, with up to 14 results displayed simultaneously.

Measurement categories include:

• Frequency
• Period
• Peak-to-peak voltage
• Maximum and minimum voltage
• RMS voltage
• Average voltage
• Rise and fall time
• Pulse width
• Duty cycle
• Overshoot
• Preshoot
• Phase
• Channel delay

Measurement statistics help users evaluate variation across repeated acquisitions.

Serial Bus Triggering and Decoding

The DHO1000 supports serial bus triggering and decoding for common embedded and automotive interfaces.

Supported protocols include:

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

The instrument can decode RS232/UART signals up to 20 Mb/s, CAN signals up to 5 Mb/s and LIN signals up to 20 Mb/s under supported conditions.

Protocol analysis helps identify:

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

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

Advanced Trigger Functions

The series 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 modes help engineers capture the relevant fault instead of reviewing large numbers of normal acquisitions.
