Libera 2BPMRTM

The Libera 2BPMRTM is a MTCA.4 RTM module intended for processing and digitizing the signals from two beam position monitors.

Product description

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.


  • 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
