Zusammenfassung:	The invention relates to a hydraulic arrangement (1, 49) for generating a series (35) of periodic fluid pressure pulses (36). The hydraulic arrangement (1, 49) comprises a synthetically commutated hydraulic pump (4), a fluid output connector (3) for an external device (2), a fluid conduit (9, 10) connecting said synthetically commutated hydraulic pump (4) and said fluid output connector (3), a triggerable orifice device arrangement (22) connected to said fluid conduit (9, 10), at least a pressure transducer (18, 33) being fluidly connected to said fluid conduit (9, 10), and a control device (6) for controlling said hydraulic arrangement (1).
