Brief introduction

This series of distortion measuring instruments is the company's newly designed all-digital automatic distortion measuring instrument series products. Its minimum distortion measurement reaches 0.005%, and the measurement frequency of the distortion signal reaches 150kHz. It is a smart with high performance/price. Type instrument.

Performance characteristics

  • With automatic distortion measurement function, signal frequency automatic measurement and display, internal automatic calibration, automatic tracking filter
  • The minimum measurable distortion is up to 0.005%
  • It has the function of automatically measuring the signal/clutter ratio (SINAD) and signal/noise ratio (S/N)
  • With the function of measuring balanced or unbalanced signals
  • Equipped with oscilloscope output monitoring jack, convenient for users to observe the waveform of the signal under test
  • Optional RS-232 interface
