S337 V2 Telecom Test PDA

S337 V2 Telecom test PDA is based on Android smart phone platform, which is a handheld multi-functional testing device design for telecom operator for LAN test, optical power test, red light source, gigabit speed test, 5G WIFI speed test, and TV functions. S337 V2 Telecom test PDA can test multiple access methods, including LAN access and optical fiber access. And it can help you confirm whether the user line can open services; evaluate the service quality you provide to the user. This device not only can simulate the user’s PC to test broadband IP line, or realize PPPoE dial through the user’s modem, but also used in problems verification, such as connectivity of the broadband IP network and the user’s modem problem, or eliminate due to the user’s PC failure cannot login the webpage.
