This PULSE software adds distortion testing capabilities to PULSE Basic Electroacoustics Type 7797. Four individual software modules are available, using either steady-state response (SSR) analysis or time-selective response (TSR) analysis:

PULSE SSR Analysis - Harmonic Distortion BZ-5548

Enables measurements of harmonic distortion using SSR analysis. Up to 60 harmonic distortion products can be measured in parallel during a single frequency scan.

PULSE SSR Analysis - Intermodulation Distortion BZ-5549

Enables measurements of intermodulation distortion using SSR analysis. It is useful for near-field measurements.  Up to 10 intermodulation distortion products can be measured in parallel during a single frequency scan. The level ratio for the two frequencies can be set by the user.

PULSE SSR Analysis - Difference Frequency Distortion BZ-5550

Enables measurements of difference frequency distortion using SSR analysis. Up to 10 difference frequency distortion products can be measured in parallel during a single frequency scan. The level ratio between the two frequencies can be set by the user.

PULSE TSR Analysis - Harmonic Distortion BZ-5742

This software enables measurements of harmonic distortion using TSR analysis. Harmonic distortion products can be measured in parallel during a single frequency sweep.

 

REQUIREMENTS

This software requires PULSE Basic Electroacoustics Type 7797.

ADDITIONAL CAPABILITIES

Our software package PULSE Electroacoustics Type 7907-S1 gives you a complete toolbox for testing. It includes all of these distortion testing software modules as standard. See the product data sheet for more information.

  • Audio engineers researching, measuring and documenting acoustical designs during development, pre-qualification and manufacturing
  • Benchmarking the acoustical performance of electroacoustic transducers such as speakers and headphones 
  • Evaluating acoustical accuracy of hydrophones, hearing aids, headsets, telephones, microphones and loudspeakers
  • Sample testing of electroacoustic transducers during production, such as tolerance checking of speaker drivers, for quality assurance
