This is a device that delayed OFDM modulation IF signal at the arbitrary set time. By using this at the relay station, OFDM modulation waves that passed different transmission route becomes possible to output by arranging delay time. Because it is possible to operate in the front side, this is excellent in maintenance. Through/delay can be switched with a front panel and a remote control is possible by the option.
