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 A.H. Systems AK-26G antenna kit series consist of five E-field
antennas, one magnetic loop antenna, and two current probes. Each of the
antennas and probes are provided with calibrations when connected to a
50 ohm input receiver or spectrum analyzer.
Each of the E-field antennas mount 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).
Cables and an adapter are provided to connect each antenna and probe to
either a BNC or N type connector on the receiver. Cable calibrations are
supplied.
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 specification requirements.
E-FIELD ANTENNAS
SAS-510-2 Log Periodic Antenna 290 MHz - 2000 MHz
The log periodic antenna comes assembled and ready to use.
Operation:
Attach the antenna to the tripod azimuth and elevation head
through the screw hole in the antenna base. Connect a cable between the
antenna connector and the receiver. The log periodic beamwidth is 65
degrees and it should be pointed or aimed in the direction that the received
signal is coming from.
