	type	array
	items	type	integer
requantisation_scale	Scale factor applied during re-quantisation that modifies the dynamic range of the fixed precision output. By default, for 2, 4, and 8 bits per sample, data will be scaled to minimize scattered power by adopting the Optimum Input Threshold Spacing for a Uniform Digitizer defined in Table 3 of Jenet & Anderson (1998; PASP 110:1467). For 16 and 32 bits per sample, by default the data will be scaled such that the maximum fixed precision output value (2^{num_bits_out-1}) corresponds to 6 times the standard deviation. For all num_bits_out, the standard deviation is that of either the real or imaginary part of each complex-valued sample. The default scale factor is computed such that, after multiplication by this scale factor, the data would satisfy the conditions described above. This default scale factor is multiplied by requantisation_scale. Therefore, a requantisation_scale value greater than 1 increases the value of the floating point data before it is cast to a fixed precision value, thereby reducing the overhead available to represent RFI and increasing the probability of clipping. Keyword: DIGITIZER_SCALE
	type	number
num_channels	The number of input channels to be recorded. This value must be less than or equal to the output_frequency_channels. Keyword: NCHAN_FT
	type	integer
requantisation_length	Length of data to be used when determining the scaling factors used for fixed precision output during re-quantisation. Units: seconds Keyword: DIGITIZER_LENGTH
	type	number
additionalProperties	True

num_filter_taps	Total number of taps in the prototype filter (i.e. over all arms) used in the stage. Keyword: NSTAP_k
	type	integer
filter_coefficients	An array of filter coefficients that define the (time domain) response function of the prototype filter used in the stage. Length of this is num_filter_taps. Keyword: COEFF_k

num_frequency_channels	The number of frequency channels output by each polyphase filter bank (PFB) for this stage. Keyword: NCHAN_PFB_k
	type	integer
oversampling_ratio	The oversampling ratio expressed as a fraction as an array of int, with the first value the numerator and the second is the denominator. (e.g. 8/7 is assigned as [8,7]). Keyword: OVERSAMP_k
