Abstract
A cost-effective scan technique enabling scalable measurement range is presented by injecting a sweep RF signal of 27.5-30 GHz into an electro-optic comb generator. The 10th-order harmonic scans over an extended span (275-300 GHz) where an ultra-narrow (Q >106) resonance is well-resolved with sub-MHz resolution.
