 DP series 2M digital transmission analyzer integrates many advantages of several kinds of imported 2M meters. It has been tried out by departments of Tele-communication, China Unicom and China Mobile in Beijing, Tianjin, Guizhou, Sichuan and Zhejiang, and has been improved several times. The final design has passed the inspection of communication measurement center, which belongs to information industry. Now we have DP-500A/B/C/D meters.
DP-500 meter is PCM2M integrated test handset, mainly used to measure the code error rate of communication line data and analyze the line fault as well as the causes. It can realize the measurement of 2M series N*64K channel transmission parameters and the daily maintenance test.
