A.H. Systems Model SAS-562B Active Loop Antenna
GENERAL USE INSTRUCTIONS
The SAS-562B loop antenna is an active loop designed to perform magnetic
field and shielding effectiveness testing. The loop antenna has a balanced
Faraday shield to reduce the E-field response for a pure magnetic field
measurement.
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 antenna factor in dB/m. The field strength is the receiver voltage in
dBV plus the antenna factor (refer to the antenna 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.
