S-265 FEATURES

• High-precision signal processing of 220kHz/24bit, has achieved a test environment with broadband, high-dynamic range.

• The basic measurement menu and optional software is comprehensive and responds to various design requirements on the site.

• 5 types of frequency characteristics (option: up to 9 types) and 3 types of data can be measured at the same time, making the experiment time more effective.

S-265 MEASUREMENT CAPABILITY

The S-265 Acoustic Analysis System has been designed to achieve the best performance and functionality, as a measurement system for standard speakers and microphones.

  1. Sound pressure frequency characteristics
  2. Total harmonic distortion (THD), 2nd and 3rd harmonic distortions
  3. Impedance characteristics
  4. Phase characteristics
  5. Sensitivity (S0)
  6. Impedance (Z0)
  7. Lowest resonance frequency (f0)

In one test, 5 types of frequency response (option: 9) & 3 data can be measured simultaneously.

S-265 SYSTEM

BASIC SYSTEM DIAGRAM

The measurement unit has one enclosure for the 20W model, and two enclosures for the 50W and 100W models; the measurement unit and the power amplifier. The entire system is composed of the test environment such as PC, microphone, and anechoic chamber, etc. Software is installed on your PC.
