## 产品列表

### Stanford Research Systems SR1 Dual-Domain Audio Analyzer
```yaml
product: stanford-research-systems-sr1-dual-domain-audio-analyzer
brand: Stanford Research Systems
price_gbp: 12536.42
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
frequency_response: 10 Hz to 200 kHz
frequency_response_accuracy: ±0.008 dB from 20 Hz to 20 kHz
```

- **价格:** £12536.42 [^1]
- **概述:** The SR1 is a professional dual-domain audio analyzer for precise analog and digital testing, with measurements up to 200 kHz, dual-channel FFTs, flexible signal generation, and digital audio interface analysis. It suits audio manufacturers, laboratories, and demanding test engineers who need very low distortion and noise performance.
- **最适合:** 其模拟分析仪噪声底指标为≤-118 dBu，同时具备≤-112 dB THD+N和±0.008 dB的频率响应平坦度，因此非常适合该问题。

### Ono Sokki CF-9200 Portable FFT Analyzer
```yaml
product: ono-sokki-cf-9200-portable-fft-analyzer
brand: Ono Sokki
price_gbp: 961495.08
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 1 MΩ ±0.5%, 100 pF or less
frequency_response: DC to 100 kHz
frequency_response_accuracy: ±0.1 dB at 1 kHz
```

- **价格:** £961495.08 [^2]
- **概述:** The CF-9200 is a portable two-channel FFT analyzer with a 10.4in touchscreen, 24-bit A/D converter, battery operation, and analysis bandwidth up to 100 kHz. It suits field engineers and laboratories measuring noise, vibration, resonance, and frequency characteristics without needing an external PC.
- **最适合:** 它非常适合用于寻找低噪声底的录音室监听音箱频率响应分析仪，因为其动态范围达到120 dB或更高，20 kHz以下的谐波失真低于-80 dB，并且在1 kHz时具有±0.1 dB的满量程精度。
