INT 204-094 / K04094 correlator report 2004 April 3 094/07:30-094/08:41 Tsukuba correlator, Japan Kyoichi Sakamoto, GSI/SED Co., Ltd. Station Comments ---------------- TSUKUB32(T/Ts): Phase cal amplitude was generally below 1% in channel X2(freq. 8252.99MHz), causing D-codes. Fringed for S-and X-band with manual phase cal. Tapes were played back with being mounted on a slave side of recorders. Wettzell(V/Wz): Error rate was higher on head "C" during playback. Tapes were played back with being mounted on a master side of recorders.
