Claim 8:
9. A method of observing a sample in a multi-beam apparatus, the method comprising:
forming, using a deflector, a plurality of deflected charged-particle beams from a primary charged-particle beam comprising a plurality of charged-particle pulses;
detecting, using a detector, a plurality of signals generated from a plurality of probe spots formed by the plurality of deflected charged-particle beams;
obtaining, using a controller, a first timing information related with formation of a deflected charged-particle beam of the plurality of charged-particle beams, and a second timing information related with detection of a signal of the plurality of signals; and
associating, using the controller, the signal with the deflected charged-particle beam based on the obtained first and second timing information.
