  The new Linac4 at CERN will pro­vide a 160 MeV H ion beam for charge-ex­change in­jec­tion into the ex­ist­ing CERN ac­cel­er­a­tor com­plex. Shorted stripline pick-ups placed in the Linac in­ter­tank re­gions and the trans­fer lines will mea­sure beam orbit, rel­a­tive beam cur­rent, beam phase, and av­er­age beam en­ergy via the time-of-flight be­tween two beam pick­ups. A pro­to­type Beam Po­si­tion Mon­i­tor (BPM) sys­tem has been in­stalled in the trans­fer line be­tween the ex­ist­ing Linac2 and the Pro­ton Syn­chro­tron Booster (PSB) in order to study and re­view the com­plete ac­qui­si­tion chain. This paper pre­sents mea­sure­ments and per­for­mance of this BPM sys­tem op­er­at­ing with 50 MeV pro­ton beams, and com­pares the re­sults with lab­o­ra­tory mea­sure­ments and elec­tro­mag­netic sim­u­la­tions.
