Testing procedure

Things that may cause "noise" that are actually due to your testing setup:

  • STB boards not securely attached to chamber. Make sure center screws (ones attaching directly to the chamber, not the nylon stand-offs) are tightened to 14 in. lb's.
  • Scope's termination set to 1Mohm. Set the scope to 50ohm termination.
  • Lower bandwidth of 1 Ghz scope to 200 Mhz. This attenuates peak height, but also rejects high frequency noise and reduces the noise level from 55-65 mV to ~11-15 mV.
