USB RF analyser for on-site analysis of LTE-U signal transmission

September 07, 2016 // By Graham Prophet
Anritsu presents its portable Site Master analyzer as delivering measurement performance in the smallest form factor on the market; the Site Master S331P has coverage to measure new LTE-U frequencies while also meeting size, speed, and cost requirements of field testing.

The S331P provides wireless operators and contractors, DAS installers, and public safety network installers and maintenance professionals with a pocket-sized headless cable and antenna analyzer that can measure the new LTE-U frequencies.


Two models covering 150 kHz to 4 GHz and 150 kHz to 6 GHz are available to support low frequency radio communications environments, including public safety networks, as well as higher frequency applications, such as LTE-U in the 5 GHz unlicensed spectrum. With a sweep speed of 500 µsec/data point, the S331P is the fastest Site Master unit.


The analyzer features an Integrated Help function to aid users in making measurements, as well as a Classic Mode of operation that maintains the standard Site Master look and feel to simplify performing tests. An Advanced Mode has a GUI with a modern button layout and functionality. Advanced Mode also expands the number of available markers to eight and has six customizable touch screen icons to quickly recall regularly used setups, making operation easier and more efficient.


Optimized for field use, the S331P comes standard with an N(m) connector for easy direct connection to N(f) devices, eliminating the need for phase-stable cables. The S331P is impact, dust, and splash resistant. It is externally controlled and powered via USB from a user-supplied Windows tablet or laptop, eliminating the need for a battery.
