Technical Deep Dive
Multi-Domain Synchronization Architecture
Features "Unified Timebase + Hardware Spectrum Engine" design: Single clock source synchronizes analog (1GHz BW), digital (16 channels), and RF (6GHz SA) domains with <1ns skew (Source: Input description). True hardware spectrum analyzer (not FFT-based) provides 100dB dynamic range for RF measurements. 20Mpoint memory with Wave Inspector® controls enables deep signal investigation. Measurement system operates on raw ADC data (not interpolated display data), guaranteeing industry-leading accuracy specifications.
| Technical Dimension | MDO4000C | Traditional Setup | Advantage |
|---|---|---|---|
| RF Analysis Capability | True hardware spectrum analyzer (6GHz) | FFT-based spectrum from oscilloscope ADC | 30dB better dynamic range for EMI troubleshooting |
| Measurement Integrity | Calculations on raw acquisition data | Many instruments use interpolated display data | Guarantees ±1% voltage accuracy vs. ±5% typical |
Wireless System Debugging Workflow
Connection: Analog probes to sensor outputs, digital probes to MCU GPIOs, RF input to antenna trace
Configuration:
- Set frequency-domain trigger: RF power >-30dBm at 2.4GHz
- Configure time-domain trigger: SPI command "TX_ENABLE"
- Enable 20Mpoint memory for all channelsAnalysis:
- Correlate RF transmission with digital control signals (latency measurement)
- Verify sensor analog output stability during RF bursts
- Measure EVM of 2.4GHz signal while monitoring power supply rippleDebugging: Use Wave Inspector® to zoom into 20Mpoint capture, identify glitches during state transitions
Multi-Domain Performance Boundary
Simultaneous operation of all instruments reduces maximum sample rate to 2.5GS/s (Based on system architecture). Mitigation: ① Prioritize critical measurements; ② For full 5GS/s analog sampling, disable unused instrument modules.
