Rigol DS1074Z-S Plus

The RIGOL DS1074Z-S Plus Digital Oscilloscope combines oscilloscope, signal-generation and mixed-signal analysis capabilities in one compact benchtop platform.

It provides:

• Four analogue oscilloscope channels
• 70 MHz analogue bandwidth
• Two built-in waveform-generator channels
• Up to 16 optional digital channels
• Up to 1 GSa/s real-time analogue sampling
• Up to 24 Mpts acquisition memory
• Up to 30,000 waveforms per second
• Up to 60,000 recorded waveform frames
• Serial protocol triggering and decoding
• FFT, waveform mathematics and mask testing
• A 7-inch WVGA colour display

The built-in signal source distinguishes the DS1074Z-S Plus from the standard DS1074Z Plus. Engineers can generate a test waveform, apply it to a circuit and observe the resulting analogue or digital response without connecting a separate function generator.

70 MHz Analogue Bandwidth

The DS1074Z-S Plus provides 70 MHz bandwidth across four analogue input channels. Its calculated rise time is approximately 5 ns.

It is suitable for analysing:

• Microcontroller clock and control signals
• PWM waveforms
• Sensor and actuator outputs
• Analogue amplifier signals
• Power-supply ripple
• Switching regulator control signals
• Audio and control circuits
• Embedded communication interfaces
• Timing and phase relationships
• Input and output waveform behaviour

The complete measurement bandwidth depends on the oscilloscope, probe bandwidth, grounding method, signal connection and source impedance.

Four Analogue Input Channels

The four-channel architecture allows engineers to monitor several related signals at the same time.

Typical four-channel measurements include:

• Clock, data and enable signals
• Input and output waveforms
• Voltage and current relationships
• Multiple power rails
• Sensor output and controller response
• High-side and low-side control signals
• Multi-stage power-up sequences
• Phase and timing comparison

This configuration is useful when a fault involves several circuit sections or when signal relationships must be observed simultaneously.

Optional 16-Channel Logic Analysis

The Plus-series digital interface supports up to 16 digital input channels when the optional RIGOL RPL1116 logic probe is connected.

The mixed-signal configuration supports:

• Microcontroller GPIO debugging
• FPGA and CPLD testing
• Parallel bus analysis
• Clock and data timing measurements
• Digital control-system troubleshooting
• Time-correlated analogue and digital display
• Triggering across analogue and digital channels
• Configurable logic thresholds

Digital sampling performance is:

• Up to 1 GSa/s with eight digital channels
• Up to 500 MSa/s with all 16 digital channels

Digital memory depth is:

• Up to 24 Mpts with eight digital channels
• Up to 12 Mpts with all 16 digital channels

The RPL1116 probe should be listed separately unless its inclusion is confirmed in the RevineTech quotation.

Channel-Dependent Analogue Sampling

The DS1074Z-S Plus provides a maximum real-time analogue sample rate of 1 GSa/s.

Sampling allocation is:

• 1 GSa/s with one active analogue channel
• 500 MSa/s per channel with two active analogue channels
• 250 MSa/s per channel with three or four active analogue channels

Engineers should consider this allocation when measuring faster signals across several channels simultaneously.

Deep Acquisition Memory

The oscilloscope provides up to 24 Mpts analogue memory depth.

Memory allocation is:

• 24 Mpts with one active analogue channel
• 12 Mpts per channel with two active analogue channels
• 6 Mpts per channel with three or four active analogue channels

Deep memory allows longer signal captures while retaining useful sample resolution.

It is beneficial for:

• Long serial communication packets
• Power-supply start-up sequences
• PWM and pulse-train analysis
• Embedded-system timing measurements
• Intermittent fault investigation
• Extended waveform monitoring
• Production validation
• Long control sequences

Search and navigation functions help users locate specific events within long acquisitions.

• Communication faults

The intensity-graded display uses up to 256 levels to distinguish frequent waveform activity from rare events.

Hardware Waveform Recording

This function allows users to:

• Record successive signal events
• Replay captured waveforms

• Examine events preceding a failure
• Perform post-acquisition measurements

Waveform recording is useful when a problem occurs only occasionally or after an extended operating period.

The DS1074Z-S Plus provides multiple trigger modes for isolating specific waveform conditions.

Trigger functions include:

• Edge
• Pulse width
• Slope
• Video
• Pattern

These triggers help engineers locate narrow pulses, missing transitions, timing errors, abnormal voltage levels and unstable waveform behaviour.

Serial Bus Triggering and Decoding

The oscilloscope supports serial protocol analysis for common embedded communication interfaces.

Supported protocols include:

• RS232 and UART
• I2C
• SPI

Protocol decoding displays communication data together with the physical waveform.

This helps identify:
