ST301B PHS CELL STATION LINE TESTER

ST301B PHS Cell Station Line Tester is used for the urgency and necessity of PHS line maintenance. It can emulate PHS cell station link function and be directly inserted into U interface to validate whether PHS cell station controller (CSC) is activated or not and line error; distinguish line fault types, such as line fault or PHS cell station fault; it can measure line parameters such as voltage, loop resistance, and mainly applied to the line maintenance and troubleshooting on PHS / lines. Local power supply and remote supply two types are available.
