Line Impedance Stablisation Networks (LISN)
Emissions
-
All commercial LISNs include an artificial hand connection and a transient limiter. This adds a 30dB insertion loss. A 30dB pre-amplifier is included which can be connected in the RF output feed to return the insertion loss to 0dB. All bar the heavy current LISNs are constructed in a flanged aluminium enclosure that can be bolted directly down to a ground plane (as required by standards). The underside of the enclosure is left unpainted to ensure good conductivity with the plane. The 16A and military/automotive LISNs have an RF output for each line, thus allowing parallel measurements of the emissions. This facilitates measurement of common mode and differential mode components of the emissions if required.

Active Loop Antenna
AL-130R
-
Also known as Magnetic Loop Antenna, the AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. It is a compact controller which can be used to enable/ disable RF measurement circuit and monitor saturation and battery low conditions remotely via a fiber optic cable up to 30 mtrs in length.
