Signal-To-Noise Ratio (SNR)

• Additional problem: Noise

• • internal noise in the measurement equipment
  • internal noise in the DUT

• Achieve an SNR as high as possible:

• • Increase the measurement duration
  • • get +3dB of SNR doubling the measurement duration
  • Increase the energy in the excitation signal:
  • • without increasing the amplitude:
    • minimize the Crest factor:
