Remark
：

 

(1) Reading in which marked as QP means measurements by using are Quasi-Peak Mode with

Detector BW=9KHz；SPA setting in RBW=10KHz,VBW =10KHz, Swp. Time = 0.3 sec./MHz。
Reading in which marked as AV means measurements by using are Average Mode with 
instrument setting in RBW=10KHz,VBW=10KHz, Swp. Time =0.3 sec./MHz。 

(2) All readings are QP Mode value unless otherwise stated AVG in column of『Note』. If  the QP 

Mode Measured value compliance with the QP Limits and lower than AVG Limits, the EUT 
shall be deemed to meet both QP & AVG Limits and then only QP Mode was measured,
but AVG Mode didn‘t perform。In this case, a “ * ” marked in AVG Mode column of 
Interference Voltage Measured。 

(3) Measuring frequency range from 150KHz to 30MHz。
