Turntables
The TT-400X and TT-600X motorized turntables are low-profile, above-ground platforms designed for EMC testing. They rotate equipment under test (EUT) to help identify angles with peak electromagnetic emissions. Suitable for tabletop or floor-mounted setups, they feature bi-directional remote control, a durable motor with gear-reduction drive, and are built from non-conductive, weather-resistant materials.

RF Clamps
Com-Power absorbing clamps (ferrite clamps) are used to measure EMI disturbance power on power and auxiliary I/O lines, compliant with CISPR 13, 14, and 32 standards. Following the ACMM method (CISPR 16-2-2, Clause 7), models CLA-050 and CLA-150 feature broadband current transformers (30 MHz to 1 GHz) with two sets of ferrite rings for accurate emissions measurement.

RF Coupling Networks & LISN
Com-Power offers Three-Phase LISNs rated from 16 to 100 Amps, compliant with CISPR 16-1-2 and ANSI C63.4. They feature manual or fiber optic remote line selection and come individually calibrated with full test data and certificates. Com-Power also provides Coupling/Decoupling Networks (CDNs) for injecting common mode disturbances and isolating Auxiliary Equipment, meeting IEC 61000-4-6 standards with 150-ohm impedance. Various CDNs are available for IEC-61000-6 testing across different cable types and connectors.

RF Probes
Com-Power Bulk Current Injection (BCI) Probes are used for RF conducted immunity testing per IEC 61000-4-6, CISPR 16-1-2, RTCA DO-160, and MIL-STD 461 standards. Designed for cases where no suitable CDN exists, these split-core probes easily clamp around cables to inductively inject RF current and test equipment susceptibility. The internal window size accommodates various cable bundles, and the probes are calibrated using a specialised coaxial fixture (sold separately) to ensure accurate, reliable measurements.

Transient Limiters
Com-Power’s LIT-153A and LIT-930A transient limiters protect spectrum analyser inputs from high-level voltage spikes during EMC conducted emissions testing. Covering 9 kHz to 30 MHz, they combine low-pass and high-pass filters, transient suppressors, and two 5 dB impedance-matching attenuation pads (at input and output) to ensure signal integrity and prevent damage. The built-in high-pass filter also reduces 50/60 Hz line feed-through for cleaner measurements.
