Mea­sure­ments were per­formed at the Swiss Light Source on the beam­line X06SA using a four-quad­rant CVD di­a­mond sen­sor which was con­nect­ed to Lib­era Pho­ton, a new pho­ton BPM de­vice from In­stru­men­ta­tion Tech­nolo­gies. The out­puts of the sen­sor are 4 cur­rent sig­nals in the nA range and are di­rect­ly con­nect­ed to the mea­sur­ing unit with­out any pre-am­pli­fiers. Ex­ter­nal bias volt­age was ap­plied, al­though the Lib­era Pho­ton can sup­ply in­ter­nal bias volt­age. Mea­sure­ments con­sist­ed of: scan­ning the mea­sure­ment range, fre­quen­cy anal­y­sis of the beam move­ment and anal­y­sis of the pho­ton beam flux in­flu­ence on the mea­sured po­si­tion. The Sen­sor was mount­ed on a mo­tor­ized XY step­per motor stage. Ac­quired data con­sist­ed of raw sig­nal am­pli­tudes and pro­cessed po­si­tions. Ac­qui­si­tions were taken at 10 kHz and 10 Hz rate.
