A.H. Systems AK-571-4 Horn Antenna Kit

GENERAL INFORMATION

INTENDED PURPOSES

This equipment is intended for general laboratory use in a wide variety of

industrial and scientific applications, and designed to be used in the

process of generating, controlling and measuring high levels of

electromagnetic Radio Frequency (RF) energy. It is the responsibility of the

user to assure that the device is operated in a location which will control the

radiated energy such that it will not cause injury and will not violate

regulatory levels of electromagnetic interference.

GENERAL DESCRIPTION

The AK-571-4 Horn Antenna kit is the newest member of A.H. Systems

family of antenna kits. This Antenna Kit provides a convenient solution for

increased frequency requirements from 700 MHz to 40 GHz. As

specifications include higher test frequency requirements so does the need

for an accurate antenna solution. Each antenna comes calibrated traceable

to NIST

Cables and an adapter are provided to connect each antenna to either a N

or SMA type connector on the receiver. Cable calibrations are supplied.

To help minimize any downtime the customer may be experiencing during

testing we provide next-day, on-time delivery.

Each antenna mounts directly to the tripod azimuth and elevation head. The

azimuth and elevation head allows the operator to vary the antenna azimuth

(direction) and to change the antenna polarity (vertical or horizontal).

To obtain the field strength of the signal being measured, the operator must

add the receiver reading in dBuV, the antenna factor in dB, and the cable

attenuation in dB. This yields the field strength in dBuV/m. Calibrations for

the E-field antennas are supplied at appropriate spacing (1, 3, and 10

meter) to comply with various test specification requirements.

The SAS-574 horn antenna comes assembled and ready to use. The

SAS-571 antenna mounting bracket is attached to the antenna backwards

in order to fit in the carrying case. The bracket must be removed from the

antenna, turned over (so that the bracket leg faces away from the antenna),
