Atec PLA-130-A User Manual

LOOP ANTENNAS

ARA TECH offers two different models (ALA-130/A and ALA-
1030/B) of active loop antennas, three different models (PLA­130/A, PLA-1030/B, and PLA-205/B) of passive loop
antennas, and two different pairs (PLA-2050 & PLH-2050 and
PLA-451 & PLH-450) of loop sensors or field pick up coils and

radiating loops.

The PLA-130/A and ALA-130/RS are designed for the
shielded room testing requirements per MIL-STD 285 and NSA
test standard 65-6. The PLA-130/RS is capable of handling 1
kW input power while the ALA-130/RS provides the dynamic
range required for shield room attenuation measurements. The
ALA-130/RS and PLA-130/A are sold together as a set known
as the APL-130/RS.

The PLA-1030/B is a single band passive loop antenna for
immunity or emission testing.

The PLA-205/B is optimized for generating fields in the low
end of the frequency band from 20 Hz to 5 MHz. It can also be
used for emission testing at low frequencies. When used with
our extremely sensitive BBH series receive antennas, it
provides the best combination for testing shielding
effectiveness in the 20 Hz to 5 MHz band.

PLA-130/A

All loop calibrations are made relative to a 50 ohm load. Active
and passive loops (except field generating coils PLH-450 and
PLH-2050 and field pick-up coils PLA-2050 and PLA-451) are
individually calibrated in accordance with procedures specified
in IEEE-291 section 2.3.1.
