Dear Experts,
I am conducting pre-scans in a 3-meter fully anechoic chamber. It is
noticed that even when no equipment is present inside the chamber the field
strength is about 20 to 25 db micro volts per meter in the frequency range 30
to 350 MHz, about 27 to 32 db micro volts per meter in the frequency range 350
to 600 MHz and about 33 to 39 db micro volts per meter in the frequency range
600 to 1000 MHz. What is the level of ambient noise permissible in fully
anechoic chambers? Which section of FCC deals with measurement site
qualifications?
Sincerely
K.Balasubramanian
Sr.Engineer, Hardware.
