A.H. Systems Model SAS-563B Active Loop Antenna

Each antenna is individually calibrated per IEEE 291-1991 and comes with a

calibration certificate references the NIST traceable test equipment. Initially

the antenna comes with a 1 year calibration interval, however depending on

the type of use and standards that the antenna is being used, this interval can

be adjusted.

The calibration tables shown provide a listing of the frequency of operation

and its correction factor in dB. The field strength is the receiver voltage in

dBV plus the correction factor (refer to the correction factor calibration) plus

any cable loss. When making a measurement, mount the antenna on an

appropriate mast or tripod with the plane of the loop antenna facing the DUT.

SHIELDING EFFECTIVNESS TESTING

Both the SAS-563B and the SAS-564 loop antenna is used for shielding

effectiveness testing. The SAS-563B is used as the receive antenna and

should be connect to an analyzer or receiver, where the SAS-564 Loop

antenna is a passive loop antenna used to transmit.
