Abstract
A variable ISI transmission channel apparatus inserted in a high-speed transmission channel for the high-speed serial data communication simulates a 'live' ISI environment to which the high-speed transmission channel in operation is exposed, in a situation such as a bit error test by means of continuously adjusting an amount of inter-symbol interference (ISI) in the high-speed transmission channel. By allowing an undersurface of a transmission loss generating member () () () such as a dielectric, a magnetic body, and an electric conductor to face, and slide on, a top surface of a conductor strip () exposed on a top surface of a plate-shaped dielectric substrate (), a facing area is continuously increased/decreased. A dielectric loss, a magnetic loss, or a resistance loss increased/decreased in the transmission loss generating member is reflected on a high-frequency signal on the conductor strip ().
