Abstract
Low level control (LLC) system based on IQ technique will be constructed for RF
cavities at Shanghai Synchrotron Radiation Facility (SSRF). There are two paths for
LLC to go through. One is based on analog IQ, another adopts all digital technique.
Some experiments of IQ control loop in our laboratory have been done, which shows
that the suppression 20dB of modulation in amplitude and phase and the loop width
over 1KHz are achieved.
Key word: IQ technique Amplitude modulation phase modulation Loop width
