We are actively upgrading BPM processors in the SPEAR3 accelerator complex as several of the existing systems are reaching end-of-life. To consolidate the resources required for development and maintenance we have evaluated and installed several processors from the Libera SPARK hardware series. We found that two common deployment methods typically used with these modules, micro-SD card and network boot, are either hard to maintain or lack flexibility. Instead we have developed an automated method based on a network boot scheme where an external EPICS soft IOC manages the assignment of specific SPARK modules to physical BPMs in the accelerator. Each module queries the soft IOC at boot time to determine which BPM it is assigned to and then starts its IOC with the appropriate BPM prefix for the PV names. This deployment method allows for quick, seamless swapping of SPARK modules by machine operators or physicists. It addition, it allows us to bring additional modules online for testing, or to move modules to different locations with a different PV prefix for the new location. This method is applicable to other EPICS-enabled devices where the device hardware also hosts an IOC.

  Filling pattern was measured at SOLEIL and APS storage ring using a 500 MHz digitizer. Various filling patterns were measured: from a single bunch to multi-bunch hybrid fill. The digitizer has 14-bit granularity and locks the sampling clock to exact RF frequency (352 MHz). Signals were sampled from the standard BPM pickup and from APD diode. Data were retrieved using Matlab and Labview interfaces and compared to existing systems.
