Claim:
1. A total station comprising: a base; a structure arranged on the base and pivotable in relation to the base about a pivot axis; an aiming unit arranged in the structure and pivotable in relation to the structure about a tilt axis perpendicular to the pivot axis; an angle measuring unit; a control and processing unit; an electro-optical distance measuring unit for measuring the distance to points on an object, wherein the distance measuring unit includes an emission unit that emits pulsed measuring radiation, which can be emitted using the aiming unit, and a detector for receiving the measuring radiation reflected at the points on the object, which registers the received measuring radiation in the form of measuring signals; a scanning functionality, which is controllable by the control and processing unit in such a manner using the distance measuring unit, a distance measurement to points on an object is executable in a scanning manner and registered measuring signals are analyzed using an analysis unit and convertible into scanning points, wherein a distance to the object can be ascertained for each scanning point from the measuring signals with assignment of two spatial angles, so that a point cloud which represents the object can be generated from the scanning points, wherein the electro-optical distance measuring unit uses runtime measurement and waveform digitizing (WFD) to carry out a distance measurement, and the total station has a program storage unit which provides at least two scanning modes, wherein the at least two scanning modes differ at least in their measuring rate, wherein, in the scope of a scanning functionality, an aiming unit is pivotable about a tilt axis and/or pivot axis in such a manner that emitted, pulsed measuring radiation is continuously aligned at least in a pivotable manner about one of two axes, so that blurring of incident and reflected pulses on a surface of an object result in blurring signals, wherein the WFD provides at least a partial compensation of these blurred signals by providing an improved ability to analyze these blurred signals.
