GAO Tek’s line testers have the following functions: 

• Voltage Testing: Our telecom line testers measure and verify the voltage levels on telephone lines to ensure they are within the acceptable range for proper operation. 
• Line Impedance Testing: Line impedance testing helps determine the resistance and impedance characteristics of telephone lines, ensuring they are within the specified limits for optimal voice communication. 
• Line Noise Testing: GAO’s telecom line testers assess the level of noise present on telephone lines, helping identify and troubleshoot potential issues that may affect call quality. 
• Signal Quality Testing: Our testers evaluate the quality of signals transmitted over telephone lines, checking for factors like distortion, echo, and signal loss. This helps in diagnosing and resolving call quality issues. 
• Line Fault Detection: GAO Tek’s telecom line testers can identify faults and issues on telephone lines, such as open circuits, short circuits, line breaks, or other abnormalities that may disrupt communication. 
• Loopback Testing: Loopback testing enables the tester to simulate a complete telephone call on the line by sending and receiving signals. This feature helps verify end-to-end connectivity and identify potential problems in the communication path. 

GAO Tek’s telecom line testers are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as IEC 61010-1, ANSI/UL 61010-1, EN 61010-1, IEC 61557, and ANSI/ISA-82.02.01.
