1. A measurement system for analysing RF signals, comprising
an optically transparent enclosure comprising an optically pumpable gas;
a printed circuit board, PCB, comprising an electrical transmission line for guiding the RF signal to be analyzed through the enclosure and a reflective planar face;
an optical pump for emitting preferably coherent light onto the reflective planar face; and
a detector for detecting an optical property of the emitted light being reflected by the reflective planar face.
