ABSTRACT:
An apparatus and method for calibrating a yttrium-iron-garnet-tuned filter (YTF) is disclosed. Instead of using both tune+span information from the 1st LO, only the sweep ramp used to span the 1st LO is used for the YTF's s own swept spans, and the YTF has its own tune information created independently of tune of the YIG oscillator. This allows calibration at any time, both in the factory or in the field.
