Abstract
A frequency plan for a signal analysis circuit includes operational parameters that are selected on the basis of first intermediate frequency (IF) filtering characteristics that are uniquely identified for the circuit. That is, rather than selecting a frequency plan based upon an original design of the circuit and circuit layout, actual IF filtering characteristics are considered. The center frequency of the passband of the first. IF filter may be measured and then used as an important factor, along with inhibiting spurious responses, in a devising the frequency plan for the specific circuit.
