Readout electronics
The readout electronics, designed to be hosted in rugged micro-TCA crates, can probe up to 400 KID per readout card over a large bandwidth (950 MHz).
A microTCA can host up to 12 of these boards and each board uses less than 40W. Each readout board heavily relies on the use of a Field Programmable Gate Array (FPGA) and fast digital to analog and digital to analog converters (2 Gigasamples per second).
The radiofrequency front-end is in charge of performing the up and down conversion of the signal between the converters and the cryostat (back and forth). This electronics is used for radioastronomy and in-house developments. The firmware of the FPGA can be adapted to photometry or spectroscopy observations.
