Pna time gated measurement
WebThis can be shown analytically and by measure-ment. With ϕ(f) = -360°·f·τ it follows from (2) that τgr = τ. For a measurement example, a coaxial cable as described can be used. A cable with 50 ns delay time produces a phase shift of 360° for a frequen-cy shift of 1 / 50 ns = 20 MHz. For an accurate tracking of the phase shift versus ...
