摘　　要：相位和幅度测量是BEPCⅡ直线加速器相控系统中最重要的部分之一．基于模拟和数字I／Q解调器,构建了两种PAD,并分别在实验室和速调管长廊进行了测试．基于LMS方法的校准算法用于补偿模拟I／Q解调器的各种不匹配误差．实验证明,两种PAD都能正常稳定地运行,可以满足相控系统对相位和幅度测量的要求．Phase and amplitude measurement is one of the most important issues for the phasing system of BEPCⅡ linac. Two kinds of PAD, based on analog and digital I/Q demodulator respectively, have been constructed and tested in both laboratory and the klystron gallery of BEPC Ⅱ linac. A calibration algorithm based on LMS method is used to compensate the mismatches of the analog I/Q demodulator. Experiments show that both kinds of PAD run stably and can meet the requirements of the phasing system.
