Cable & Antenna & PIM Analyzers

S331P Site Master Ultraportable Cable and Antenna Analyzer

The S331P is an ultraportable version of the industry-leading Site Master Series of Cable and Antenna Analyzers. It is the smallest, lightest, fastest, and most cost effective instrument in the Site Master family. No battery is required, since the USB port of Windows 7, 8 & 10 tablet devices, laptops or desktop PCs power it. Available with two frequency ranges starting from 150 kHz up to 4 GHz and 150 kHz to 6 GHz, it is the only small headless Site Master product capable of measurements down to 150 kHz for low frequency radio communications applications and up to 6 GHz for higher frequency applications like LTE-U in the 5 GHz unlicensed spectrum. Compatible with the Smart Aligner Android application for the generation of site close out reports including antenna alignment results from Multiwave tools and line sweep results.
