Four new models, each with expanded and new features, have joined the Site Master family of analzyers. The units combine the cable and antenna analysis capability of previous models with RF signal monitoring and spectrum analysis capabilities. The resulting handheld instruments can be used to deploy and maintenance wireless networks and cellular sites. The S114B combines a 1200-MHz cable and antenna analyzer with a full-featured spectrum analyzer. For higher frequencies, the S332B offers coverage to 3300 MHz. The two other units, Models S113B and S331B, offer upgraded performance versus existing models.
