Hi Friends,
I would like to double-check whether my following interpretation is correct. Please elucidate me. For the following ptp4l output, the ptp4l reports rms value and the max deviation from the mean offset. Thus, if I have to report the worstcase accuracy, I take the (rms+max). For example, , looking at the first line, I see that the maximum offset uncertainty/inaccuracy observed is 2 +7 = 9ns. The maximum frequency uncertainty is (156403 + 7) pbb. ptp4l[833.369]: rms 2 max 7 freq -156403 +/- 7 delay 28 +/- 0 ptp4l[834.399]: rms 2 max 7 freq -156403 +/- 8 delay 29 +/- 0 ptp4l[835.428]: rms 2 max 7 freq -156403 +/- 7 ptp4l[836.457]: rms 2 max 6 freq -156403 +/- 7 delay 28 +/- 0 ptp4l[837.487]: rms 2 max 6 freq -156403 +/- 7 delay 28 +/- 0 ptp4l[838.516]: rms 2 max 6 freq -156403 +/- 7 delay 27 +/- 0 ptp4l[839.549]: rms 2 max 7 freq -156403 +/- 7 ptp4l[840.583]: rms 2 max 8 freq -156403 +/- 8 delay 29 +/- 0 Thanking you in anticipation, Regards, Chandra (c) : +60.175508142 (O): +60.4.636.6412 "Knowledge speaks, Wisdom listens" ________________________________ Confidentiality Notice.
