Embodiment Construction
[0062] Below according to accompanying drawing and embodiment the present invention will be described in further detail:
[0063] The present invention adopts the control device to control the SDH analyzer (such as the OmniBER series SDH analyzer of Agilent Company), and will select the pointer sequence, change the frequency offset, and record the test data. The test results; and use the port selection board to realize the automatic selection of multi-channel PDH signals, and can continuously test multiple PDH branch output ports. After each port is tested, it will automatically switch to the next port to start testing until all signals are tested. User pre-specified port.
[0064] Such as figure 2 Shown is the connection schematic diagram of the present invention combined with the jitter automatic test, the test signal is sent by the SDH analyzer, a control device is connected to the SDH analyzer and the port selection board through two RS232 serial interface lines, and the...
