	Cavity BPM signal processing system normally consists of two modules, first one is RF conditioning module to down convert the BPM signal to IF, second one is IF signal digitizer and digital signal processing module. The conditioning module complicates the system and introduce noise. A direct RF sampling system has been constructed to process the cavity BPM signal, which structure is more concise and performance is more stable compared to the conventional system. The platform and test results will be introduced in this paper.

Beam current is one of the fundamental parameters to be measured in storage ring. The Shanghai Synchrotron Radiation Facility (SSRF), a third generation light source with the RF frequency of 499.68MHz, used adopt com-mercial product to monitor beam charge. However, the maintain and upgrade is not always straightforward. Thus, a new type of beam charge monitor (BCM) based on beam positon monitor (BPM) sum signals has been de-veloped for the online beam current measurement on SSRF storage ring. This system has been convincingly validated by mathematical analysis and has been demonstrated with beam experiments during machine study time.
