  1. Barth CDM Measurement Components ImproveRepeatability With Accurate Characteristics“Measure what is measurable; make measurable what is not”Galileo Exhibitor Showcase 9/13/2016

  2. CDM Data Suffered Large Variations Too Many Years • Different CDM Standards have different peak current parameters • Data Within Each Standard are Different • We have designed new components • They and new Specs will Fix this problem Exhibitor Showcase 9/13/2016

  3. Change in Current Sensor Design • Produced Excessive Variations • Increased JEDEC and ESDA differences • Resonant Cavity raised 1 GHz response • But it added: • Ringing of discharge waveform & • Questionable affects in CDM Failure levels Exhibitor Showcase 9/13/2016

  4. Model 4106 Current Sensor RCDM3 Exhibitor Showcase 9/13/2016

  5. Model 4181 Verification Module Exhibitor Showcase 9/13/2016

  6. Positioning Model 4181A Verification Modules Offset In Place Exhibitor Showcase 9/13/2016

  7. Changes to CDM Standards • Making CDM what it should be • New frequency specifications for: • Current Sensor response • Verification Module (Reference Capacitor) • Scope Response (Bandwidth and roll-off) • Coaxial cable attenuation END Exhibitor Showcase 9/13/2016
