A.H. Systems Model SAS-562B Active Loop Antenna

SPECIFICATIONS

GENERAL DESCRIPTION

The A.H. Systems active loop antenna is a receiving antenna that covers the 
10 KHz – 30 MHz frequency range. This loop antenna is ideal for emissions 
testing and has a balanced Faraday shield to reduce the E-field response for 
a pure magnetic field measurement. Review this manual and become familiar 
with all safety markings and instructions.
