VXI based multibunch detector and QPSK modulator for the PEP-II/ALS/DA{Phi}NE longitudinal feedback system

PDF Version Also Available for Download.

Description

The PEP-II/ALS/DA{Phi}NE feedback systems are complex systems implemented using analog, digital and microwave circuits. The VXI hardware implementation for the Front-end and Back-end analog processing modules is presented. The Front-end module produces a baseband beam phase signal from pickups using a microwave tone burst generator. The Back-end VXI module generates an AM/QPSK modulated signal from a baseband correction signal computed in a digital signal processor. These components are implemented in VXI packages that allow a wide spectrum of system functions including a 120 MHz bandwidth rms detector, reference phase servo, woofer link to the RF control system, standard VXI status/control, ... continued below
