he next generation ground based Gamma Ray Telescope, the Cherenkov Telescope Array (CTA), will have a large number of telescopes at two sites and is expected to be sensitive to γ rays in the range between 10 GeV and 300 TeV. γ rays produce air showers in the atmosphere whose particles emit short flashes of Cherenkov light. Fast cameras with special read-out electronics have been developed to allow for very short (nanosecond) exposure. The TARGET ASICs, with its high sampling rate (1 GSample/s) and 12 bit precision, are supposed to fulfill the scientific goals of CTA Furthermore, it provides Level 0 trigger information, small package sizes, high integration (16 channels/ASIC), deep buffer for trigger latency (16k samples) and low costs per channel. This makes it a perfect canditate to be implemented in the compact small size cameras of CTA. For a first camera prototype 54 electronics modules featuring TARGET with 16x54 channels in total where produced. The results of the commissioning tests will be presented.
