Abstract
For future near infrared astronomy missions, ESA is developing a complete detection and conversion chain (photon to SpaceWire chain system):
Large Format Array (aLFA-N) based on MCT type detectors.
aLFA-C (Astronomy Large Format Array Controller): a versatile cryogenic detector controller.

An aLFA-C prototype was developed by Caeleste (Belgium) under ESA contract (400106260400). To validate independently the performances of the aLFA-C prototype and consolidate the definition of the follow-on activity, a dedicated test bench has been designed and developed in ESTEC/ESA within the Payload Technology Validation group. This paper presents the test setup and the performance validation of the first prototype of this controller at room and cryogenic temperature. Test setup and software needed to test the HAWAII-2RG and aLFA-N detectors with the aLFA-C prototype at cryogenic temperature will be also presented.
