Application
Until recently, radiated emission test site validation re-
quirements and procedures existed only for frequencies
between 30 MHz and 1 GHz. Validation requirements
at higher frequencies remained "under consideration"
literally for decades.
The eventual implementation of (>1 GHz) requirements in
CISPR 16-1-4 came in the form of the so-called site voltage
standing-wave ratio (S
VSWR
) procedure. In this procedure,
a transmitting source antenna is placed in several posi-
tions within, and around the perimeter of, an imaginary
cylindrical test volume, in which Equipment Under Test
(EUT) would be located during testing. As the physical
dimensions and types of radiating structures/apertures
will vary depending on the EUT, it must be assumed that
any EUT could potentially radiate energy in any given
direction. Therefore, the transmit source antenna must
have a relatively uniform radiation pattern in order to
eff ectively "illuminate" the entire test volume and sur-
rounding area equally, or else potential refl ections that
could occur during testing will be masked.
Since the ABM-6000 has a true "dipole-like" radiation
pattern, as described in CISPR 16-1-4, it is the ideal choice
as the transmit source antenna for test site validations
using the S
VSWR
procedure.
The ABM-6000 can also be used in a variety of applica-
tions such as, amplifi er harmonic measurements per
IEC 61000-4-3 or fi eld surveys. It is ideal in almost any
application necessitating measurements of high level
signals with minimum fi eld disruption.
Description
The ABM-6000 is a precisely tuned, linearly polarized,
mini-biconical dipole antenna, operating at the low end
of the microwave band over the frequency range of 1 to
6 GHz. It may be used as either a transmitting or receiv-
ing antenna.
The ABM-6000 was specifi cally designed to comply with
radiation pattern specifi cations detailed in CISPR 16-1-4
(section 8.2.2.1), and is intended to be used as the trans-
mit source antenna for site validations above 1 GHz for
radiated emissions test sites, such as OATS (open area
test sites), anechoic and semi-anechoic chambers.
Its lightweight, compact design makes the antenna eas-
ily portable, while its stainless steel housing and brass
elements provide durability, enabling the antenna to be
transported and used in almost any environment. The
textured, powder-coated handle section of the shaft along
with the supplied mounting clamp allow for easy mount-
ing of the antenna on any tripod or antenna mast.
Each antenna is individually calibrated per ANSI C63.5:
2006 at 3 meters distance.
The antenna is supplied with a protective carrying case,
mounting clamp, user's manual, calibration data and cer-
tifi cate. Com-Power also off ers several non-conductive
tripods.
