nanoVNA Isolation & Noise

• Understanding Crosstalk and Isolation Plots - pickering
• Kurt Poulsen "My Outlook 2019 sucks"
  • test cable by cal std
  • cal kit links
  • Cables length calibrated away
  • unterminated cable for adjusting load delay
  • Some basic knowledge about a transmission line
  • If the NanoVNA could provide a negative Electrical delay it could be fixed.
• Erik CH1 noise
  • Dynamic Range
  • Noise vs Leakage on CH1
  • S21 20dB dynamic range increase for 433MHz filter
  • S21 measurement limitation analysis 650MHz dip
    from out-of-phase leakage cancelling 50dB attenuated signal
  • S21 @ 900Mhz limited by leakage
  • Supply noise at 300-1600MHz   absolute levels by console sample command
• hwalker LNA S21 procedure
