RIGOL DS7034 Digital Oscilloscope Overview

The RIGOL DS7034 is a professional four-channel digital storage oscilloscope developed for engineers who need higher analogue bandwidth, deep acquisition memory and rapid waveform capture in a flexible benchtop instrument.

With 350 MHz analogue bandwidth, the DS7034 can analyse faster clocks, switching transitions, control signals, communication interfaces and power-conversion waveforms than 100 MHz or 200 MHz oscilloscopes. It is suitable for electronics research, embedded-system development, automotive testing, industrial automation, manufacturing and advanced educational laboratories.

The DS7034 belongs to the RIGOL MSO/DS7000 family. This series uses RIGOL’s proprietary Phoenix core technology platform and UltraVision II architecture. The official model specifications list four analogue channels, a maximum real-time sample rate of 10 GSa/s, 100 Mpts standard memory and a waveform capture rate of up to 600,000 waveforms per second.

The oscilloscope includes:

• Four analogue input channels
• One external trigger input
• 350 MHz standard bandwidth
• Up to 10 GSa/s real-time sampling
• 100 Mpts standard acquisition memory
• Optional expansion to 250 Mpts or 500 Mpts
• Up to 600,000 waveform captures per second
• Hardware waveform recording and playback
• Full-memory automatic measurements
• Advanced trigger functions
• Optional serial-bus trigger and decode
• Optional power-analysis software
• Enhanced FFT and peak search
• Built-in digital voltmeter
• Six-digit frequency counter and totaliser
• 10.1-inch capacitive multi-touch display
• LAN, USB, HDMI, GPIB and Web Control

The DS7034 is the digital-storage version of the platform. It does not include the 16-channel logic-analyser interface or dual-channel arbitrary waveform generator available with compatible MSO7000 models.

350 MHz Analogue Bandwidth

The DS7034 provides 350 MHz analogue bandwidth across four input channels. This makes it suitable for circuits containing faster rise times, higher clock frequencies and wider spectral content.

Typical signals include:

• Microcontroller and processor clocks
• FPGA control and timing signals
• High-speed PWM waveforms
• Gate-driver signals
• Switching-node transitions
• Automotive electronic control signals
• Oscillator outputs
• Communication transceiver signals
• Industrial motor-drive waveforms
• Power-converter control loops
• Sensor excitation and output signals
• Fast pulse and timing circuits
• RF envelope and modulation signals

A 350 MHz oscilloscope is particularly useful when signal integrity depends on more than the fundamental frequency. Digital and switching waveforms contain higher-frequency harmonic content that determines edge shape, ringing, overshoot and settling behaviour.

Upgradeable to 500 MHz

The DS7034 can be electronically upgraded from 350 MHz to 500 MHz using the official DS7000-BW3T5 bandwidth-upgrade option.

This upgrade is compatible specifically with the DS7034 and MSO7034 models. It allows laboratories to increase bandwidth without replacing the oscilloscope hardware.

The upgrade path protects the initial equipment investment when future projects require measurement of faster interfaces or switching devices.

Four Analogue Channels

Four analogue channels allow engineers to observe several circuit nodes during the same acquisition.

Typical four-channel measurements include:

• Input voltage, gate drive, switching current and output voltage
• Clock, data, enable and reset
• Three motor phases and a current-feedback signal
• Multiple power rails during start-up
• Primary voltage, primary current, secondary voltage and secondary current
• Sensor output, reference voltage, excitation signal and supply voltage
• PWM signal, feedback signal, fault output and current sense
• Transmit, receive, clock and control signals

Viewing related signals together helps reveal propagation delay, phase relationships, incorrect sequencing and interactions between circuit stages.

The separate external trigger input can be used to initiate acquisition without using one of the four primary analogue channels.

Up to 10 GSa/s Real-Time Sampling

The RIGOL DS7034 supports a maximum real-time sample rate of 10 GSa/s.

Sampling resources are allocated according to the number and grouping of active analogue channels.

Channels 1 and 2 form one acquisition group, while channels 3 and 4 form the second group. When one channel from each group is active, each can operate at up to 5 GSa/s. When all four channels are active, the maximum rate is 2.5 GSa/s per channel.

A high sampling rate provides more acquisition points across fast signal transitions and helps engineers analyse:

• Rise and fall times
• Overshoot and undershoot
• Ringing
• Narrow glitches
• Pulse distortion
• Timing skew
• Switching transients
• Clock instability
• Communication signal quality
• Short-duration disturbances

The high bandwidth-to-sample-rate ratio makes the DS7034 suitable for detailed time-domain analysis of fast electronic signals.

100 Mpts Standard Memory

The DS7034 is supplied with 100 Mpts acquisition memory as standard. Official memory options expand the maximum record length to:

• 250 Mpts with DS7000-2RL
• 500 Mpts with DS7000-5RL

RIGOL lists both deep-memory upgrades for the complete 7000 Series.

With the 500 Mpts option installed, the maximum memory is allocated according to the active-channel configuration.

The 500 Mpts figure represents the maximum acquisition-system capacity. It is not independently available on every channel when multiple channels are active.

Deep memory allows users to capture a long time interval while retaining a high sample rate. This is important when the signal contains both long-duration system activity and short events that require detailed examination.

Applications include:

• Complete power-up and shutdown sequences
• Long serial communication transactions
• Motor acceleration and braking cycles
• Intermittent system resets
• Protection events
• Long PWM control sequences
• Burst-mode power-converter operation
• Sporadic communication errors
• Thermal or load-related behaviour
• Extended production-test records

After acquisition, the user can zoom into a small section without losing the context of the complete waveform.

Up to 600,000 Waveforms per Second

The DS7034 supports a maximum waveform capture rate of up to 600,000 waveforms per second under specified operating conditions.

A fast capture rate reduces the dead time between acquisitions. This improves the probability of displaying rare or intermittent events, including:

• Random glitches
• Missing pulses
• Noise bursts
• Signal dropouts
• Timing violations
• Metastable transitions
• Communication errors
• Unstable switching edges
• Occasional protection trips
• Unexpected circuit resets

The intensity-grading display represents the frequency of waveform occurrence. Repetitive waveform paths appear more prominently, while less frequent signal behaviour remains visible as a lower-probability event.

Hardware Waveform Recording and Playback

The DS7034 supports hardware-based waveform recording, analysis and playback of up to approximately 450,000 frames in single-channel operation.

Segmented acquisition stores only events that meet the configured trigger condition. Long periods of inactivity between events do not consume the complete acquisition memory.

This function is useful for:

• Capturing intermittent electronic faults
• Recording communication errors
• Monitoring power-converter protection events
• Investigating automotive ECU problems
• Analysing motor-drive trips
• Evaluating repeated production failures
• Recording random noise
• Capturing oscillator instability
• Reviewing changing start-up behaviour

Each frame can be reviewed individually. Time information helps users identify the sequence and spacing of stored events.

10.1-Inch Capacitive Touchscreen

The RIGOL DS7034 uses a 10.1-inch capacitive colour touchscreen with a resolution of 1024 × 600 pixels.

The large display gives users enough space to view:

• Four analogue waveforms
• Automatic measurements
• Protocol decoding
• FFT traces
• Trigger settings
• Measurement statistics
• Cursors
• Menu controls

Touch gestures can be used to:

• Reposition waveforms
• Change vertical scale
• Adjust the horizontal time base
• Set trigger level
• Position cursors
• Select measurements
• Navigate long acquisitions
• Expand waveform regions
• Operate analysis menus

Traditional buttons and rotary controls remain available for conventional oscilloscope operation. A USB mouse may also be connected.

Full-Memory Hardware Measurements

The DS7034 can calculate measurement results across the full acquired waveform record rather than analysing only the data displayed on the screen.

This capability is valuable when working with:

• Long acquisition records
• Burst signals
• Start-up sequences
• Modulated signals
• Signals containing different frequency components
• Changing duty cycles
• Intermittent pulses
• Communication transactions
• Motor-control sequences

The oscilloscope supports 41 automatic waveform parameters and can display up to ten measurement results simultaneously.

Automatic Waveform Measurements

Available measurements include voltage, time, pulse, phase and statistical parameters.

Measurement statistics help users assess signal stability across repeated acquisitions and identify changes that may not be visible in a single measurement result.

Advanced Trigger System

The DS7034 includes a broad selection of standard trigger modes for isolating particular waveform conditions.

Standard triggers include:

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

These triggers allow acquisition based on signal amplitude, timing, pulse shape, logic pattern or transition behaviour.

Optional serial-bus trigger packages add support for:

• RS232 and UART
• I²C
• SPI
• CAN
• LIN
• FlexRay
• I²S
• MIL-STD-1553
•  

Zone Triggering

Zone triggering offers a graphical method of isolating waveform conditions.

The user draws one or more regions directly on the touchscreen and configures the oscilloscope to trigger when the waveform:

• Intersects the selected zone
• Avoids the selected zone

This is useful when an abnormal event is visually recognisable but difficult to describe with conventional trigger values.

Zone triggering can help isolate:

• Excessive overshoot
• Ringing
• Missing transitions
• Unexpected waveform paths
• Amplitude instability
• Timing jitter
• Pulse-shape distortion
• Signal excursions outside an acceptable area

It can be used together with recording, protocol analysis and pass/fail testing.

Serial-Bus Trigger and Decode

The DS7034 can analyse supported serial protocols through its analogue input channels when the appropriate software licence is installed.

RIGOL currently lists these protocol packages as individual trigger-and-analysis options for the 7000 Series.

Decoded data can be displayed alongside the electrical waveform. This allows engineers to relate protocol-level information to physical-layer conditions such as:

• Noise
• Incorrect amplitude
• Slow edges
• Ringing
• Timing errors
• Missing acknowledgements
• Invalid data
• Bus contention

Typical applications include embedded electronics, automotive systems, industrial controllers, audio interfaces and avionics communication.

Enhanced FFT Analysis

The DS7034 includes an enhanced Fast Fourier Transform function for analysing signals in the frequency domain.

FFT analysis can help identify:

• Harmonics
• Switching noise
• Clock feed-through
• Power-supply ripple
• Oscillator spurs
• Modulation components
• Resonance
• Electromagnetic interference sources
• Unwanted frequency components

The FFT function supports:

• Record lengths up to 1 Mpts
• Automatic peak search
• Up to 15 identified peaks
• Colour probability display
• User-selectable thresholds
• Several window functions

Available FFT windows include:

• Rectangular
• Blackman-Harris
• Hanning
• Hamming
• Flattop
• Triangle

Colour FFT visually separates frequently occurring spectral components from intermittent frequency activity.

Logic operations

• AND
• OR
• XOR
• NOT

These functions help users compare channels, derive calculated signals and examine relationships between voltage, current and control waveforms.

Digital Filtering

Built-in digital filter types include:

• Low-pass
• High-pass
• Band-pass
• Band-stop

Filtering can help suppress unwanted signal components and isolate the frequency range relevant to the measurement.

Waveform Histogram Analysis

Histogram analysis displays the distribution of waveform positions or measurement values across repeated acquisitions.

It can be used to evaluate:

• Timing jitter
• Amplitude variation
• Noise distribution
• Frequency stability
• Pulse-width consistency
• Duty-cycle variation
• Manufacturing tolerances
• Long-term drift

Histograms provide more information than a single measurement because they reveal the statistical behaviour of the signal over time.

Hardware Pass/Fail Testing
