Filed: 1986-04-07
Abstract: PURPOSE:To simplify management and control, by specifying the rising and falling state of a waveform pattern generated in a memory only depending on time information to facilitate the generation of a test waveform pattern. CONSTITUTION:A head address of a waveform pattern to be generated is set on an address counter/accessing circuit 16 from a test sequence processor 14 and a clock generation circuit 18 is started. Then, a head address value of a pattern data memory 12 is read out to be set on a counter 15 and the counter 15 is decremented according to a signal of the counter 18 to zero the value thereof. Then, a signal of the counter 15 is outputted to a waveform generation circuit 13 to cause a waveform to rise while it is outputted to the circuit 16 to update the address value and the next address of the memory 12 is accessed to set the value read out on the counter 15. The counter is decremented according to the signal from the circuit 18 and then, a signal generated when the counter value is zero is sent out to the circuit 13, with which a waveform is caused to fall.

IPC: H04B10/29
Filed: 1982-05-14
Abstract: PURPOSE:To obtain a large quenching rate and remove the necessity of consideration of insertion loss by making a demultiplexer to have a construction so that it separates and amplifies only a fixed wavelength by means of a semiconductor laser. CONSTITUTION:For instance, three wavelengths lambda1, lambda2 and lambda3 are made incident to an incident terminal 1. They are branched respectively by a branch circuit 5 and made incident to semiconductor lasers 6-8. The central wavelengths of gains of the lasers 6-8 are lambda1, lambda2 and lambda3, and three waves of lambda1-lambda3 are seperated by the lasers 6-8. In this case, the inrush current of lasers 6-8 is kept at a value less than threshold current Ith such as 0.99Ith. As a result, a large quenching rate is obtained and there is no need to consider insertion loss because only a specific wavelength can be separated and amplified.
