Amplifier Testing

Amplifier Test Solution

The FX100 Audio Analyzer is ideally suited for comprehensive, yet fast verification of amplifiers and other audio devices. The instrument allows execution of virtually all possible measurements within less than one second.

Quality testing of professional & consumer audio products is an essential part in the production process and the service aspect over the life cycle of an audio product. Based on varying product needs, you may choose either basic functional tests or complete performance tests, including documentation of results. In either case, your test setup remains the same, minimizing the cost of ownership and providing maximum flexibility.

At a glance

  • Audio quality testing
  • Professional or consumer audio
  • Simultaneous or sequential measurements


A typical amplifier test setup utilizes a resistive load (typically 4 or 8 Ohm) at the amplifier output.

The supported measurements for amplifier testing are:
  • Frequency response (high resolution)
  • Level relative
  • Gain
  • Signal-to-Noise ratio (S/N)
  • THD, THD+N, Harmonics k2 - k35
  • IMD
  • FFT
  • PureSound transient steepness analysis
  • Phase
  • DC Level
  • Crosstalk
