Technical Deep Dive
Precision ASIC Architecture
Features "Custom ASIC + 14-bit ADC" design: Application-specific integrated circuit reduces injected noise by 50% compared to general-purpose oscilloscopes (Source: Input description). 14-bit ADC provides 4x more vertical resolution (65,536 levels) than standard 12-bit scopes (4,096 levels). 100Mpts deep memory captures long signal sequences without decimation. Zone triggering enables visual signal isolation by drawing on-screen boxes (response time <100ms).
Technical Dimension | Precision Oscilloscope | General-Purpose Scope | Advantage |
---|---|---|---|
Signal Clarity | 50µV noise floor + 14-bit resolution | 150-200µV noise + 8-12 bit resolution | 3-4x better small-signal visibility |
Glitch Detection | 1.3M wfms/s + Fault Hunter automation | 50-100k wfms/s + manual analysis | 26x faster anomaly capture with automated reporting |
Low-Noise Amplifier Validation Workflow
Connection: Probe amplifier output (gain=1000), set vertical scale to 500µV/div
Configuration:
- Enable 14-bit high-resolution mode
- Draw zone trigger around expected signal range (avoiding noise floor)
- Activate Fault Hunter for automatic anomaly detectionTesting:
- Measure RMS noise: <50µV (passes medical device requirements)
- Capture transient response to 10µV input step
- Run Bode plot analysis (0.1Hz-10MHz) to verify stability marginsReporting: Generate Fault Hunter report with flagged anomalies, export histogram of noise distribution
Measurement Environment Boundary
50µV noise floor requires lab temperature ≤25°C (Based on thermal noise characteristics). Mitigation: ① Use active cooling for probe/scope; ② For high-temp environments, enable 8x averaging (reduces noise to 6.25µV but lowers update rate).
