... When using a single spectral window, and observing spectral lines, the bandwidth of the ATCA can be problematically narrow, or the channel widths can be too coarse. ... A partial work around for this situation is to use the two ATCA frequency bands to observe in adjacent somewhat overlapping windows, and using the same bandwidths and channel counts for the two windows. ... In so doing, it handles any overlap region between the two windows in a sensible fashion. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
