S33xD device

At MTT-S IMS 2007, Anritsu Co. unveiled its 2MHz and 6GHz cable and antenna frequency extensions to its S331D/S332D Site Master cable and antenna analyzers. The Site Master 6GHz extension allows users to accurately measure signals in the 4.9GHz public safety and 5.8GHz ISM bands, while the 2MHz extension makes the analyzers suited for defense and aerospace applications in which HF coverage is needed.

With these new options, the inherent advantages of the S331D/S332D are now available over the entire 2MHz to 6GHz frequency range. Their sweep rate of 3.5ms/dp is superior to alternative handheld instruments and they weigh less than comparable units. The analyzers' high sensitivity allows them to identify poor connections, damaged cables, water penetration and bad antennas before they become costly system failures.

Compact and easy to use, S331D/S332D allow precise Return Loss/SWR, cable loss and optional T1/E1 and power meter measurements to be made during the deployment, installation and maintenance of wireless networks. They use the frequency domain reflectometry (FDR) technique, which allows more accurate distance to fault (DTF) analysis to be conducted. These capabilities allow field engineers and technicians to easily identify and solve RF system problems such as coverage, interference and other path-related signal problems.

The S332D also includes 100kHz to 3GHz spectrum analysis for extra versatility in a single instrument. It provides users with fast measurement capability, as all key measurements, such as field strength, occupied bandwidth, channel power, adjacent channel power ratio, interference analysis and carrier-to-interference ratio, can be made with a single button. Other options offered in the S331D/S332D include the GPS receiver and the high accuracy power meter.

In addition to the public safety, IMS and aerospace/defense applications, the S331D/S332D can be used in other wireless applications. Field technicians can use the analyzers to install, provision, maintain and troubleshoot VHF, broadcasting, paging, cellular, PCS/GSM, 3G, ISM, WLAN and WLL systems.
