The S311D Site Master is a Cable and Antenna Analyzer. The Site Master S311D is the perfect instrument for Land Mobile Radio (LMR) and Public Safety system technicians testing the RF performance of P25 and TETRA radios in the VHF/UHF, 700 MHz and 800 MHz bands. With its 2 MHz frequency coverage, the Site Master works well for defense applications in the HF band. The S311D is also ideal for broadcast and cellular applications.
The high performance 1600 MHz Site Master S311D can be used to sweep cables and antennas at the frequency of operation using the Return Loss and VSWR measurements. The Distance-To-Fault (DTF) measurement can easily spot poor connections, contamination, damaged cables, water penetration, and bad antennas. Site Master Frequency Domain Reflectometry (FDR) techniques break away from the traditional fix-after-failure maintenance process by finding small, hard to identify problems before major failures occur.
S311D's High Accuracy Power Meter option enables users to make high accuracy RMS measurements, perfect for both CW and digitally modulated signals such as CDMA/EV-DO, GSM/EDGE, P25 and TETRA. Master Software Tools provides the user with comprehensive data management and post processing tools which augment the capabilities of the Site Master S311D.
Weighing less than 5 lbs (2.3 kg) with its rechargeable NiMH battery, the S311D Site Master moves effortlessly from ground installations to anywhere where critical measurements are needed.
