Classification: CPC G | IPC G

Claim 4:
5. A method for controlling a measurement apparatus, comprising the steps of:
determining, by a trigger device, a state of a state machine, the state machine comprising a number of n states, wherein n is an integer number equal or greater than 2, wherein a new state of the state machine is set based on a current state of the state machine and a signal received from a device under test when the state machine receives the signal from the device under test;
initiating, by the trigger device, a data acquisition operation of measurement data measured by a measurement device upon a predetermined trigger condition being met, wherein the predetermined trigger condition comprises that the current state of the state machine is in a preset trigger state condition which specifies a desired state of the state machine and at least one further condition of a signal for initiating a trigger event is met;
storing, by a state data memory, a history of state data of the state machine;

if the predetermined trigger condition has not been reached within a predetermined period of time, amending, by the trigger device, the preset trigger state condition to another trigger state condition which specifies another desired state of the state machine based on a predetermined order of the states of the state machine,
wherein the predetermined period of time is measured from a point in time when the measurement apparatus is set to a data acquisition mode or the device under test changes to a predetermined signal state, and
if the another trigger state condition has not been reached within a timeout period, initiating, by the trigger device, the data acquisition operation of the measurement data measured by the measurement device; and
storing, by a state data memory, a history of state data including a change of a state of the state machine and a time stamp of a point of time when the state of the state machine changes.
