5 GHz Analogue Bandwidth

The DS70504 provides up to 5 GHz analogue bandwidth through its 50 Ω signal path.

At the 1 MΩ input setting, the maximum bandwidth is 500 MHz.

The 5 GHz bandwidth is suitable for:

• High-speed serial data analysis
• Signal-integrity testing
• DDR memory debugging
• FPGA and processor validation
• Fast clock measurements
• Semiconductor characterisation
• Communication-system development
• High-speed pulse analysis
• Compliance preparation
• Transmission-line troubleshooting

The calculated rise time at 5 GHz is approximately 70 ps, although the applicable official rise-time limit should be used for formal verification and procurement documentation.

Four Analogue Channels

The DS70504 includes:

• Four analogue measurement channels
• One dedicated external trigger input

Four channels allow engineers to acquire multiple related signals in the same time-correlated record.

Typical measurements include:

• Clock and data
• Differential signal pairs
• Read and write data lanes
• Multiple high-speed clocks
• Input and output timing
• Power and control signals
• Reference and trigger signals
• Parallel bus activity
•  

Up to 20 GSa/s Real-Time Sampling

The maximum real-time sample rate depends on the active-channel arrangement.

The product should therefore be described as providing up to 20 GSa/s, rather than 20 GSa/s independently on every channel in all acquisition modes.

High sample density improves waveform reconstruction when examining:

• Fast signal edges
• Narrow pulses
• Jitter
• Overshoot and ringing
• Serial data transitions
• Clock stability
• Setup and hold timing
• Intermittent glitches
•  

Deep Acquisition Memory

The DS70504 includes 500 Mpts standard memory and can be upgraded to a maximum of 2 Gpts.

The official RIGOL product page states that the optional memory enables a 100 ms acquisition at the maximum 20 GSa/s sample rate.

Typical maximum memory allocation is:

Deep memory allows engineers to capture long signal intervals while retaining detailed sample information.

It is especially useful for:

• Long serial communication records
• DDR command and data captures
• Power-up and shutdown sequences
• Intermittent fault investigation
• Long packet analysis
• Multi-cycle jitter testing
• Detailed waveform zooming
• Extended timing measurements

The specification should be written as up to 2 Gpts, because the available depth depends on the active-channel configuration.

Up to 1,000,000 wfms/s Capture Rate

The DS70504 provides a waveform capture rate of up to 1,000,000 waveforms per second.

Fast waveform capture reduces acquisition dead time and increases the probability of detecting:

• Rare glitches
• Runt pulses
• Timing violations
• Signal dropouts
• Intermittent noise
• Unstable clock behaviour
• Abnormal transitions
• Infrequent serial-link faults

RIGOL lists one million waveforms per second as a core capability of the DS70000 Series.

Up to 2,000,000 Recording Frames

The segmented waveform-recording system can store up to 2,000,000 frames.

This allows engineers to:

• Capture triggered events over extended tests
• Replay acquisitions
• Review individual frames
• Compare normal and abnormal signals
• Search for intermittent conditions
• Analyse faults after an unattended test
• Reduce storage of inactive waveform intervals

RIGOL confirms that the deep memory can be segmented to record up to two million frames.

Selectable 8-Bit to 16-Bit Resolution

The DS70504 supports selectable acquisition resolution.

Available settings include:

• 8-bit standard acquisition
• 9-bit High Resolution
• 10-bit High Resolution
• 12-bit High Resolution
• 14-bit High Resolution
• 16-bit High Resolution

Higher-resolution acquisition reduces visible noise and improves the separation of small amplitude variations.

It is useful for:

• Power-rail ripple measurement
• Low-level analogue signals
• Precision amplitude analysis
• Sensor measurements
• Power-integrity testing
• Audio and analogue circuitry
• Small signals riding on larger waveforms

Maximum available bandwidth decreases as the selected vertical resolution increases. RIGOL describes the system as directly selectable up to 16-bit resolution.

UltraVision III is designed to maintain responsive operation even when analysing large waveform records.

Up to 10,000 FFTs per Second

The DS70504 can perform up to 10,000 FFT calculations per second using hardware acceleration.

This is useful for:

• Harmonic analysis
• Switching-frequency measurement
• Oscillation detection
• Clock-spur analysis
• Noise investigation
• Frequency-domain troubleshooting
• Filter evaluation
• Power electronics

RIGOL describes the resulting frequency-domain experience as similar to real-time spectrum analysis.

Optional UltraReal Real-Time Spectrum Analysis

The DS70504 can be upgraded with RIGOL’s UltraReal real-time spectrum-analysis capability.

The option allows the oscilloscope to perform frequency-domain analysis of time-varying signals.

Possible functions include:

• Real-time spectrum display
• Spectrogram
• Waterfall analysis
• Frequency-versus-time analysis
• RF interference investigation
• Transient spectrum analysis
• EMI troubleshooting
• Harmonic and spur detection

This combined time-domain and frequency-domain platform can reduce the need for a separate spectrum analyser during many debugging tasks.

The spectrum-analysis capability is optional and should not be described as standard.

Real-Time Eye Diagram Analysis

With the applicable jitter and eye-analysis licence, the DS70504 supports real-time eye diagrams across the analogue channels.

Available eye measurements include:

•  

Clock Recovery

The eye and jitter applications support multiple clock-recovery methods:

• Constant clock recovery
  • Automatic
  • Semi-automatic
  • Manual
• First-order PLL
• Second-order PLL
• Explicit clock

Clock recovery is required when analysing serial data streams that do not provide a separate reference clock.

Jitter Analysis

The optional jitter package supports detailed timing analysis of serial clocks, data streams and parallel buses.

Measurements can include:

• Period jitter
• Cycle-to-cycle jitter
• Time interval error
• Jitter trend
• Jitter histogram
• Jitter spectrum
• Deterministic jitter
• Random jitter
• Total jitter
• Duty-cycle distortion
• Periodic jitter

Jitter analysis helps engineers identify whether timing variation is caused by random noise, periodic interference, data-dependent behaviour or other deterministic sources.

Optional protocol applications support common embedded, automotive, audio and aerospace interfaces.

Depending on the installed licences, supported buses can include:

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