The signal transfer is based on ADC/DAC and optical fiber between the center of TAMA and the end station of TAMA. Accordingly, three NIM units are used for this purpose at the center and end separately. These NIM units are called analog_link and named as 'WE', 'NS_A', and 'NS_B'. They offer 4 channels of input and 4 channels of output. We summarize their channels information on this page.
