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.

USE SCENARIOS

  • 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

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.
