Anritsu S331B Cable & Antenna Analyzer 25 MHz to 3.3 GHz
Description
The S331B, with frequency coverage of 25 MHz to 3300 MHz, is ideally suited for users who work in VHF, broadcasting, paging, cellular, PCS/GSM and ISM and WLL frequency bands. Both S331B and S332B can replace the S300A and the S331A Site Master models. The newly improved user interface, large VGA display, real time clock, alphanumeric trace naming, field replaceable battery and up to 517 data points and 200 trace storage make these two Site Master models ideally suited for any experience level user in commissioning and maintenance of today's wireless systems infrastructures. The S331B performs precision return loss/SWR, cable loss and distance-to-fault measurements in the presence of RF interference. An optional power monitoring is available to make power measurement quickly and easily.
