MetroQ 4 Digit 3 Range Digital Distortion Meter DSM 201

The MetroQ DSM 201 Digital Distortion Meter is a high-precision instrument designed for measuring harmonic distortion in audio signals. It operates within a frequency range of 20Hz to 20kHz, providing accurate readings through its 4-digit display. The device is equipped with a highly selective balancing network that effectively filters out the fundamental frequency, allowing for precise measurement of distortion components. This makes it ideal for audio testing, research, and development, where accuracy is critical for assessing signal integrity.

Key Features:

• Frequency Range: 20Hz to 20kHz, ideal for audio applications.
• Measurement Range: Offers three selectable ranges of 2%, 20%, and 100% full scale, enabling users to measure varying levels of distortion.
• High Accuracy: ±2% of full scale, ensuring reliable readings.
• Input Voltage Range: Supports input voltages from 50mV to 10V, allowing compatibility with various audio sources.
• Fundamental Rejection: Over 60 dB for accurate isolation of distortion components.
• Residual Distortion: Less than 0.05%, ensuring minimal interference from the device itself.
