摘要：The invention relates to an arrangement and to a method for generating areference impulse (RI) for a position measuring device comprising a material measure (10)having at least one incremental track (20) and at least one reference mark (32), and to ascanning device (40) for generating position signals (PO, P90) by scanning the at least oneincremental track (20) and for generating an analog reference impulse (RI_A) by scanningthe at least one reference mark (32). The arrangement according to the inventioncomprises a reference impulse storage unit (200), in which the analog reference impulse(RI_A) can be stored as a stored reference impulse (RI_M). The stored reference impulse(RI_M) and the at least one position signal (PO, P90) are fed to a reference impulsegenerating unit (220) which switches on reference impulse (RI) according to the storedreference impulse (RI_M) and to the occurrence of a set condition and which switches offthe reference impulse when a reset condition occurs, wherein the set and resetconditions can be derived from the at least one position signal (PO, P90). The inventionfurther relates to a position measuring device having an arrangement according to theinvention.
