Abstract :
An extension of existing multiplex BPM electronics which provides the capability for phase advance measurement is implemented. One resonantly excites the stored beam then detect relative betatron phase of all BPMs by lock-in amplifier. Design considerations of the system and preliminary test results are presented in this report. Based on the rapid measurement capability and analysis methodology, possible applications of the system are betatron phase measurement, betatron function measurement, local coupling parameter study, and determination of lattice errors
