OEM electronic systems for combination with VIAMP module


KETEK’s highly integrated OEM system is designed for combination with the VIAMP module and comprises a high-performance digital pulse processor (applies for VICO-DV only), temperature controller, and high voltage supply for the SDD.

The VICO-AV is the analog variant without the VICO-DP.

The small dimensions of the VICO-DV / AV guarantee flexible integration into your system. The device can be used with SDD sizes from 7 mm² (H7) to 50 mm² (H50) collimated area.

  • VICO-DV: Digital – with VICO-DP Digital Pulse Processor

  • VICO-AV: Analog – with a ramped reset-type preamplifier output

  • Small dimensions 95 x 50 x 19 mm3

  • Temperature controller and HV supply for SDD

  • Ramped reset type preamplifier output

  • High-speed USB 2.0 and RS-232 interfaces (VICO-DV only)
