... There are four independent correlator boards available in the correlator spectrometer. Each board can be assigned any available bandwidth, center frequency, sampling level, polarization, and number of channels. ... Sampling level: Your data can be sampled with either 3-level, 3-level interleaved, or 9-level sampling. 9-level operation achieves 98% of the signal-to-noise of analog correlation, whereas 3-level sampling achieves 81%. ... You cannot use 9-level sampling with a 50-MHz bandpass. ...
