Abstract: The present invention relates to methods for enabling use of a pluggable module in a host system, regardless of the type of pluggable module used in view of the module ports of the host system, which is realized using an adaptation device. The disclosure also relates to corresponding devices; adaptation devices and host systems. The methods comprise inserting a pluggable module in a module port of a host system, obtaining information indicating an electrical interface of pluggable module and setting a mode of operation of the adaptation device for re-routing and adapting signals to/from the pluggable module towards one or more controlling entities of the host system based on the electrical interface of the pluggable module.

Abstract: A method and device for measuring the return loss of a radiofrequency signal at a feeding circuit coupled to a load, wherein the forward power and the reflected power are sensed by a measuring circuit having first and second branches (11, 12) for transferring a derived forward signal and a derived reflected signal, respectively. The return loss is calculated on the basis of the sensed power levels (P1, P2) of the derived signals in the first and second branches. The sensing range of power levels (P2) to be sensed in one branch (12) is adjusted in response to the sensed power level (P1) in the other branch (11), whereby the dynamic range required for power sensing in the measuring circuit is reduced.
