1. A coplanar waveguide (CPW) probe assembly, comprising:
- at least one center probe element, each having a respective center probe contact point; and
at least one peripheral probe element, each having a respective peripheral contact point,wherein a pitch of said at least one center contact and said at least one peripheral contact is adjustable, a physical separation between said at least one center contact and said at least one peripheral contact is controlled by a longitudinal translation of a movable sleeve fitted to an outer wall of said CPW probe assembly and a calibration indication is associated with a position of said movable sleeve.

7. A test probe assembly comprising:
-
a micro-coaxial cable having at least one center conductor and a conductive outer wall; a probe tip section comprising at least one center contact, each respectively extending from one of said at least one center conductor, and at least one peripheral contact, each electrically connected to said conductive outer wall, a pitch between said at least one center contact and said at least one peripheral contact being adjustable; a sleeve that is longitudinally movable along said outer wall, each said at least one peripheral contact being attached to said outer wall such that a longitudinal movement of said sleeve causes said adjustable pitch; and a calibration scale on said outer wall to provide an indication of a value of said pitch based on a position of said sleeve. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
