An Advanced Autocorrelation Spectrometer for the FCRAO

焦平面阵列自相关光谱仪（FAAS）将在 为了实现15个元素的全部潜力， 五学院射电天文台的阵列接收器 （FCRAO）. 这个16，384通道自相关器将利用 相关器芯片由荷兰基金会开发， 天文学研究。 的基本时钟速率 相关器为40MHz。 FAAS将提供1024光谱 信道，带宽为20 MHz，用于 阵列接收机 火焰原子吸收光谱仪可以对 输入信号达到200公里/秒带宽， CO J = 1 - 0跃迁的分辨率为1km/sec。 FAAS是 设计成也作为一个单一的赫布里底光谱仪操作， 接收机 每个接收器大约有15000个通道 带宽

A Focal Plane Array Autocorrelation Spectrometer (FAAS) will be built in order to realize the full potential of a 15 element array receiver at the Five College Radio Astronomy Observatory (FCRAO). This 16,384 channel autocorrelator will utilize correlator chips developed by the Netherlands Foundation for Research in Astronomy. The fundamental clock rate of the correlator is 40MHz. The FAAS will provide 1024 spectral channels, with 20MHz bandwidth, for each of the elements of the array receiver. The FAAS spectrometer can time multiplex the input signal to achieve 200km/sec of bandwidth and approximately 1km/sec resolution for the CO J=1-0 transition. The FAAS is designed to operate also as a hebrid spectrometer for a single receiver. With approximately 15000 channels per receiver bandwidth.
