We have developed a delay profile adapter for 800MHz-band OFDM-FPU. This adapter displays multi-path fading environments, received electric field strength and bit error rate, etc. on a NTSC monitor. Moreover, the function that the receptions such as the profile information, various alarms can be transmitted can be possessed, and use it also for the excellent automatic switch function received from two or more reception points most to select the one automatically.
