Rigol MSO2202A-S

The RIGOL MSO2202A-S Mixed-Signal Oscilloscope combines oscilloscope, logic-analysis and waveform-generation capabilities in one benchtop instrument. It is designed for engineers, technicians, research laboratories, electronics manufacturers and educational institutions that need to generate test signals while observing analogue and digital circuit behaviour.

The instrument provides:

• Two analogue oscilloscope channels
• 200 MHz analogue bandwidth
• Sixteen digital logic channels
• Two waveform-generator output channels
• Up to 2 GSa/s analogue sampling
• Up to 1 GSa/s digital sampling
• Deep analogue and digital acquisition memory
• Protocol triggering and decoding
• Hardware waveform recording
• FFT and waveform mathematics
• An 8-inch colour display

The integrated signal source distinguishes the MSO2202A-S from the standard MSO2202A. Engineers can generate a stimulus signal, apply it to a circuit and monitor the resulting analogue and digital behaviour without connecting a separate function generator.

200 MHz Analogue Bandwidth

The MSO2202A-S provides 200 MHz bandwidth across two analogue input channels. Its calculated rise time is approximately 1.8 ns, making it suitable for embedded controllers, digital interfaces, switching circuits and general electronics development.

Typical measurements include:

• Microcontroller clock signals
• FPGA and CPLD outputs
• PWM and pulse waveforms
• Switching power-supply control signals
• Sensor and actuator outputs
• Analogue amplifier signals
• Communication interface waveforms
• Timing and phase relationships
• Input and output waveform comparison
• General signal-integrity troubleshooting

The oscilloscope provides selectable 1 MΩ and 50 Ω input impedance, allowing engineers to work with general high-impedance measurements and correctly terminated higher-frequency signals.

Two Analogue and 16 Digital Channels

The mixed-signal architecture combines analogue waveform measurement with digital logic analysis.

The MSO2202A-S supports:

• Two analogue input channels
• Sixteen digital channels through a compatible RPL2316 logic probe
• Time-correlated analogue and digital display
• Triggering from analogue or digital sources
• Digital channel grouping and labelling
• Parallel bus analysis
• Configurable digital logic thresholds

This configuration is useful for analysing:

• Analogue sensor signals and digital controller responses
• Clock, data and enable relationships
• Microcontroller GPIO activity
• FPGA timing
• Parallel buses
• Power-rail behaviour during logic switching
• Communication signals and electrical waveform quality
• Mixed analogue and digital fault conditions

The digital inputs are arranged in two groups of eight channels. Each group can use a separate logic threshold.

Analogue Sampling Performance

The analogue acquisition system provides:

• Up to 2 GSa/s with one analogue channel active
• Up to 1 GSa/s per channel with both analogue channels active

The peak-detect function can capture narrow pulses of approximately:

• 500 ps in single-channel operation
• 1 ns in dual-channel operation

The high sampling rate helps reveal waveform details such as overshoot, ringing, short glitches, timing variation and pulse distortion.

Digital Sampling Performance

The digital sample rate depends on the number of enabled logic channels:

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

Digital peak-detection performance is approximately:

• 1 ns with eight channels
• 2 ns with 16 channels

The minimum detectable digital pulse width is approximately 5 ns.

The 2 GSa/s value applies to the analogue acquisition system. The digital logic channels provide a maximum sample rate of 1 GSa/s.

Deep Analogue Acquisition Memory

The oscilloscope provides 14 Mpts standard analogue memory in single-channel operation.

Standard analogue memory allocation:

• 14 Mpts with one analogue channel
• 7 Mpts per channel with two analogue channels

The optional memory upgrade increases acquisition depth to:

• 56 Mpts with one analogue channel
• 28 Mpts per channel with two analogue channels

Deep memory allows longer waveform captures while retaining a useful sample rate. It is beneficial for:

• Serial communication analysis
• Long pulse trains
• Converter start-up testing
• Embedded timing sequences
• PWM analysis
• Communication packet testing
• Intermittent fault investigation
• Production monitoring

The 56 Mpts memory depth must be listed as optional unless the appropriate memory licence is installed.

Digital Acquisition Memory

Digital memory is allocated according to the number of active digital channels.

Standard digital memory:

• 14 Mpts with up to eight digital channels
• 7 Mpts with all 16 digital channels

Optional digital memory:

• 28 Mpts with up to eight digital channels
• 14 Mpts with all 16 digital channels

This supports longer logic captures during parallel bus testing, FPGA debugging and embedded-system timing analysis.
