Anritsu Company Introduces New Generation of Site Master™ Handheld Cable and Antenna Analyzer

— S331L Delivers High Reliability, Ruggedness, Eight-Hour Battery Life and Ease-of-Use When Deploying, Installing, and Maintaining Wireless Networks —


Morgan Hill, CA – June 19th, 2012 – Anritsu Company introduces the Site Master S331L Cable and Antenna Analyzer, a new generation of rugged handheld field instrumentation that builds off the field-proven design and success of the Site Master to provide high-performance cable and antenna analysis quickly and accurately. Reliable, durable, easy-to-use, and offering eight hours of continuous battery life, the S331L is a cost-efficient tool for tower contractors, installation and maintenance contractors, and wireless service providers to ensure optimum deployment, installation, and maintenance of wireless networks.

The S331L, which covers 2 MHz to 4 GHz, brings a high level of performance to return loss, cable loss, and Distance-to-Fault (DTF) measurements. It has the highest RF immunity of any Site Master. A sweep speed per data point of 1.5 msec (typical) saves technicians time and enables easier identification of intermittent problems in real time. Helping ensure measurement accuracy is the standard built-in InstaCal™, which provides fast one-connection calibration anytime, anywhere. The S331L also features a standard built-in power meter, for easy, convenient testing of RF power in field environments.

With eight hours of continuous battery life, the S331L allows field technicians to conduct a full day’s testing on a single charge. Intelligent power-saving features – such as sleep mode and auto-display brightness that automatically reduces the screen’s backlight when the analyzer is not in use – can extend battery life well beyond the continuous eight hour rating.

The S331L features the field-proven Site Master design. It is dust- and splash-resistant, has a backlit 7-inch TFT touch screen display, and weighs under 2 kg (4.4 lbs), including battery. The rugged design and compact size make the S331L well suited for any field application, including level ground, climbing large towers, or climbing through a roof hatch.

Managing measurement results has never been easier than with the S331L. More than 1,000 files, such as sweeps, setups, and screenshots, can be stored internally on the analyzer. Every Anritsu Site Master S331L also includes SweepMasters DIRECT. An easy-to-use online trace delivery system, SweepMasters DIRECT allows S331L users to capture, upload, and deliver traces. Site traces can be emailed as links to the stored traces, as well as a .PDF report containing plots of the uploaded traces.

The S331L can also be used with Sweep Master Pro™, an enterprise-level, web-based line sweep and tracking tool for large multiple cell-site installation and maintenance projects, and Line Sweep Tools (LST), a free PC-based program that increases productivity for users responsible for numerous cable and antenna traces daily.

The S331L is available in two to three weeks ARO.
