第2.0章節(jié)

The maximum peak conducted output power is defined as the maximum power level measured with a peak detector using a filter with width and shape of which is sufficient to accept the signal bandwidth.However, when a filter with adequate width is not available, an integrated method utilizing a peak detector is acceptable.

新版本刪除積分法測試The maximum peak conducted output power

The procedures provided herein for measuring the maximum conducted (average) output power assume the use of the occupied bandwidth (OBW) as the reference for power integration. See ANSI C63.10 for guidance pertaining to measuring the OBW. Either of the two methods specified in C63.10 are acceptable, but the methodology for measuring the 99% OBW is the most accurate for noise-like emissions and thus represents the preferred method.

新版本特別提及99%OBW更為精準

第9.0章節(jié)

The maximum peak conducted output power may be measured using a broadband peak RF power meter. The power meter shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector.

新版本刪除power meter 說明

Change Notice

04/08/2016: 558074 D01 DTS Meas Guidance v03r04 changed to 558074 D01 DTS Meas Guidance v03r05Updated to note ：

<span background:yellow;"="" style="font-size: 15px">the new rules for devices operating in 5725 – 5850 MHz band and to implement editorial changes made apparent through KDB inquiries, to include the deletion of a statement regarding the use of integration peak power measurement procedures that was rendered obsolete by previous changes implemented on 06/06/2014.

KDB中新版本的變化，總的來說在測試或者報告中基本上沒什么變化，報告中更行版本號即可！即，第2.0章節(jié)中描述最大傳導功率（The maximum peak conducted output power）刪除舊版特別提及的無法滿足peak detector,則可以用積分法替代。
