The Stanford Research Systems NW is an acoustic attenuation wedge designed to reduce ambient noise in laboratory environments where sensitive measurements demand minimal acoustic interference. Built by a manufacturer with four decades of experience in precision test and measurement instrumentation, the NW integrates noise cancellation principles to suppress unwanted sound during low-level signal recovery and other noise-critical applications.
Technical Specifications
The NW operates on adaptive noise cancellation principles, employing inverse signal generation to create destructive interference with ambient noise. The system detects incoming acoustic signals and synthesizes an opposing signal equal in magnitude and opposite in phase, suppressing unwanted background noise.
– Key Features
• Acoustic attenuation for laboratory measurement environments
• Adaptive filtering capable of real-time adjustment under changing acoustic conditions
• Designed for integration with sensitive measurement instrumentation
• Leverages Stanford Research Systems’ DSP-based signal processing technologies
– Typical Applications
The NW is suited for:
• Lock-in amplifier systems recovering low-level signals from noisy backgrounds
• Precision timing measurements requiring acoustic isolation
• Signal generation and characterization in acoustically demanding lab spaces
• Any measurement environment where ambient noise limits instrument sensitivity or measurement resolution
– Compatibility & Integration
The NW complements Stanford Research Systems’ broader instrument ecosystem, including lock-in amplifiers with dynamic reserves exceeding 100 dB, precision signal generators spanning DC to several GHz, and universal time interval counters with picosecond resolution capabilities. Integration with computer-controlled measurement systems is supported through standard interfaces available on companion SRS instrumentation.
