Product No: VVLA-30M
The VVLA-30M Triple Loop Antenna (also called Van Veen Three Loop Antenna) is used for magnetic field radiated interference testing in the 9kHz~30MHz frequency band. Equipped with a 50Ω/BNC universal interface, it can be used with LISUN EMI-9K series EMI Receivers and is also compatible with mainstream EMI test receivers of the same specifications on the market. For details on LISUN’s new triple-loop antenna design, please click here: This product adopts a screwless quick-installation structure, making assembly and debugging convenient. It comes standard with a height-adjustable and expandable test platform (maximum load 50kg), eliminating the need for an additional test table. The X/Y/Z three-axis orthogonal design enables full-angle testing without displacement, effectively avoiding displacement errors. It is professionally calibrated before leaving the factory, and the antenna integrates a self-calibrating mechanism. This product is used for EMC compliance testing of electrical lighting and similar equipment, VVLA-30M Triple Loop Antenna was recommend to be used in the LISUN SDR-5000B RF Shielding Room or AC-3M Semi-Anechoic Chamber.

Note: The LISUN LS-LNA09K1000 preamplifier is optional and is mainly used to amplify weak electromagnetic signals so that test instruments (such as the LISUN SPA-3P6G Spectrum Analyzer or the LISUN EMI-9K series EMI Receivers) can more accurately detect and analyze these signals. EMC testing aims to evaluate the device’s immunity to electromagnetic interference and the level of electromagnetic interference it generates, and the preamplifier plays a crucial role in this process.
