The aim of this paper is to discuss the rationale for, development, and use of a remote access experiment facility for use in the teaching and learning of microelectronic circuit design and test principles. In particular, the operation and test of a phase-locked loop (PLL) circuit is the primary focus. In this arrangement, a set of existing experiments for the learning of the principles of operation of the PLL have been updated for remote access capability via a standard internet link. This arrangement provides for a range of tests to be undertaken by a remote learner with access to the PLL test board arrangement. This arrangement has been achieved by the modification to an existing remote laboratory arrangement in order to facilitate access to the PLL test board.
