Abstract

PURPOSE:To measure an error rate under severer condition to fluctuate a mark rate and to widely shorten a pull in time by sending a test pattern signal to have the arbitrary mark rate to a measured system, receiving the signal and adopting a mark rate recovering circuit in a receiving side. CONSTITUTION:A 1/2<m> mark rate pattern is sent from a transmission part 21 to a measured system 22 as a test signal. On the other hand, in a reception part 23, the mark rate pattern is made from a reception signal through the measured system 22 and an M system false random pattern is synchronizing- reproduced of a (2N<-1>) bit in a synchronizing circuit 29. The 1/2<m> mark rate pattern is generated in a receiving side 1/2<m> mark rate pattern generating circuit 34 and compared with a reception pattern in an error detecting circuit 37 and an error in reception pattern is detected. Thus, the mark rate is fluctuated and the error rate can be measured under the severer condition. Then, the pull in time is shortened.
