Accordingly, Ericsson recommended that the Commission amend section 22.917 to permit measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. Ericsson also recommended modification of the measurement bandwidth aspects in both sections 22.917 and 24.238 ``to explicitly permit the use of integration to improve measurement accuracy.'' Ericsson proposed modifying these sections to state that ``[a] narrower resolution bandwidth is permitted in all cases to improve measurement accuracy provided the measured power is integrated over the full required measurement bandwidth (i.e. 100 KHz or 1% of emission bandwidth, as specified).''
