Technical Deep Dive
Precision Measurement Architecture
Features "14-bit ADC + Custom ASIC Processing" design: High-resolution ADC captures small signal details (4x more vertical levels than 12-bit systems) (Source: Input description). Custom ASIC enables 1.3M wfms/s update rate with real-time zone triggering. 100Mpts memory depth (per channel) combined with 1GHz bandwidth captures long-duration high-speed signals. 10.1" capacitive touchscreen with split-grid view enables simultaneous time/frequency domain analysis.
| Technical Dimension | HD3 Series | Traditional Oscilloscope | Advantage |
|---|---|---|---|
| Signal Fidelity | 14-bit ADC (65,536 vertical levels) | 8-bit (256 levels) typical | 256x better resolution for power ripple/SNR measurements |
| Anomaly Capture | 1.3M wfms/s + zone triggering | 50-100k wfms/s typical | 26x faster capture of intermittent glitches |
Power Supply Validation Workflow
Connection: Probe 12V CPU power rail, set 200MHz bandwidth limit, enable high-resolution mode
Configuration:
- Vertical scale: 50mV/div (14-bit mode resolves 3µV steps)
- Zone trigger: Define exclusion zone around nominal 12.00V (±20mV)
- Memory: Set 10Mpts for 5ms capture durationTesting:
- Measure RMS noise: <50µV (pass) / >50µV (fail)
- Capture load transients: Verify overshoot <5% during 10A step load
- Analyze ripple spectrum with FFT (identify switching frequency harmonics)Reporting: Generate compliance report with ripple/transient screenshots, flag violations
Measurement Accuracy Boundary
At 1GHz bandwidth, noise floor increases to 80µV RMS (vs 50µV at 200MHz) (Based on typical scope characteristics). Mitigation: ① Enable bandwidth limit filter (200MHz) for sensitive measurements; ② Use averaging mode (reduces noise 4x at expense of update rate).
