This is a follow up to then January 11, 2022 .3ck ad-hoc for mellitz_3ck_adhoc_01_011222. The attached is 4-page presentation for what I thought may be apparent discussion trends. The text in the slides are as follows: ____________________________________________ Proposal 1: Separate CM voltage specification by frequency Comment: # I-101 & # I-10 Separate low and high frequency measured common mode voltage
o) V_CM(HF) is V_CM filtered with a high pass 4th order Bessel Thomson filter with 3 dB point a f(HF)cm f(LF)cm=f(HF)cm -->100 MHz ____________________________________________ Proposal 2: for CL 163 and Annex 120F Comments: # I-101 & # I-102 VCMPP_LF (max) --> 30 mV (new line in tables) o) Used for low frequency SCMRHF(min) --> 15 dB o) Used for high frequency ____________________________________________ Proposal 3: Replace CMS RMS with VCMPP Comments: # I-103, # I-104, and # I-105 VCMPP = 233 mV (table 162-10, #I-103) VCMPP = 213 mV (table 120G-1, #I-104 and table 120G-3, #I-105) Note LF/HF was not included in these comments 3 o) LF/HF and correlated vs. uncorrelated adjustments could addressed when more data is available. Some of these values could become a straw ballot. Please indicate suggestions in that respect. Comments are also welcome. I’m also asking if you would support this presentation.
