Com-Power ABM-6000 Application

Until recently, radiated emission test site validation requirements 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 (SVSWR) procedure. In this procedure, a transmitting source antenna is placed in several positions 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 effectively  “illuminate” the entire test volume and surrounding area equally, or else potential reflections 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 Svswr procedure.

The ABM-6000 can also be used in a variety of applications such as, amplifi er harmonic measurements per IEC 61000-4-3 or field surveys. It is ideal in almost any application necessitating measurements of high level signals with minimum field disruption.
