Libera 2BPMRTM general description:
The module features 8 input channels with analog front-end customized for the BPM application for electron synchrotrons. Channels are equipped with a programmable attenuator and combination of low-pass and band-pass signals from the pickups. Typically, the central frequencies are around 352 MHz and 500 MHz but others can be supported, too.
Highlights:
- Eight input channels with 125 MHz 16-bit A7D converters
- Analog front-end with customized filtering and amplification
- RJ-45 interfaces to control the external switching module
- D1.2 backplane connector for the AMC module
- FPGA and software support
