Here are two questions that have been running around my head: 1. Following on from the discussion last week about trying to synchronize multiple oscillators to improve phase noise, I've wondered about a simpler tack: take, for example, two 5 MHz atomic standards and mix their outputs together, using the 10 MHz result to drive a time scale. Assuming the standards were of relatively equal quality, would this provide a better time scale than using one of the standards alone? 2. Several measurement techniques require a given phase relationship (e.g., quadrature) between DUT and reference. For HF frequencies (ie, 5 or 10 MHz) is there a *practical* phase shifter design covering 180+ degrees that doesn't involve switching various lengths of coax in and out of the line? Happy holidays!
