The option a is also acceptable in some standards such as GR-1089-CORE. 

For each frequency step; The modulation has to be turned off, adjust the
level, apply modulation… It is quite time consuming

Again, this method is not for EN 61000-4-3

        Could you please  help:

         

        Could you explain what is  the correct procedure when using an anechoic
chamber which is  calibrated and operating to EN61000-4-3.

         

        During calibration of the chamber,   a calibration file is made and it 
is
assessed according to the guidelines laid down under BS EN61000-4-3. During
calibration the chamber is empty.

         

        During a normal test run a UUT is put into the chamber. The questions 
is :

         

        a)      Do you use the calibration file as the starting point and 
adjust the
field strength which may have changed due to the UUT being in the chamber.

        b)      Just take the calibration file and run it and except the filed
strengths would have changed due to the UUT being in the chamber.

         

         

        Thanks
