8121C Noise Generator & 8121FT-1 Weighting Filter – Professional Solution for Loudspeaker Testing
In modern audio testing, accurate and standardized signal generation is essential for evaluating loudspeaker performance. The combination of Model 8121C Noise Generator and 8121FT-1 Weighting Filter provides a reliable and cost-effective solution for speaker life testing and power handling evaluation.
🔊 8121C Noise Generator – High-Precision Audio Noise Source
The 8121C Noise Generator is designed using advanced pseudo-random noise technology, delivering stable and accurate audio test signals.
Key Features:
- Generates multiple noise types:
- White Noise
- Pink Noise
- 3 types of Weighted Noise
- Built-in power amplifier (up to 100W output)
- Integrated True RMS voltage meter for accurate measurement
- Wide frequency response:
- White noise: 20Hz – 100kHz
- Pink noise: 20Hz – 20kHz
- Excellent flatness and stability for reliable testing
👉 Compared with traditional diode-based generators, the 8121C offers much flatter frequency response and higher accuracy
🎚️ 8121FT-1 Weighting Filter – IEC 60268-1 Standard Compliance
The 8121FT-1 is a dedicated weighting filter designed to work with the 8121C.
Main Functions:
- Complies with IEC 60268-1 (IEC-268-1) standard
- Generates standardized weighted noise for:
- Loudspeaker life testing
