Abstract
Energetic Cosmos Laboratory is developing Kinetic Inductance Detectors (MKID) for mm/submm astronomy purposes. In order to measure the instantaneous resonance frequency and dissipation of superconducting microresonators of the MKID arrays, we have developed a data acquisition system with emphasis on precision, readout speed and digital processing capabilities. We use IQ mixer to down convert the MKIDs signal in the range of 20-80 MHz, then digitize them by 250 MSPS ADC. Processed data at FPGA-Kintex 7 will be transferred to the PC for further analysis by the rate of 10 Gbit/sec. In this report, we describe the technical details and the algorithm we developed.

Summary
The Energetic Cosmos Laboratory investigates the birth and evolution of the universe using state-of the art instrumentation. In order to measure the instantaneous resonance frequency and dissipation of superconducting microresonators of the MKID arrays, we have developed a data acquisition system with emphasis on precision, readout speed and digital processing capabilities. We use IQ mixer to down convert the MKIDs signal in the range of 2080 MHz, digitize them by 250 MSPS ADC.
