Abstract
A system is described which employs two decade sets of local oscillators to separate signal power into a bank of 100 identical filters. By commutating the local oscillators, filter instabilities are removed from the resulting output and local oscillator stability is the remaining factor. Practical limits on this are discussed in relation to the total output uncertainty of the spectrometer.
