Overview
  • Features two simultaneous measurement and frequency diversity
  • Sample analysis by high-speed high-precision Area
  • BCH by demodulator alarm information check
  • 5 hours battery operation

ML8741B Area Scanner is the scanner for a test drive is done during the optimization of base station area.  The high hardware performance, measured in high-interference environments, so you can get a reliable radio propagation characteristics, can be optimized without wasting area. 
Frequency measurements by two options, two different frequencies is W-CDMA base stations can be measured simultaneously.  You can dramatically improve the efficiency of drive test data collection. 
In addition, BCH by demodulator software, be sure to set the value of the cell base station and traffic information, and discovery of base stations can not afford to traffic can be configured to prevent leakage.
