Abstract
A digital acquisition system maximizes the number of points captured when a user issues a stop command, while maximizing the update rate during continuous operation. In essence, the present invention utilizes an optimum update rate (i.e., set so as to capture a minimum number of points), while operating in a continuous fashion. Upon receiving a stop command for the user, the present invention sets up to take a deep memory acquisition at a slower update rate (i.e., set so as to capture a maximum number of points). If a trigger is received within a predetermined period of time after the stop command is received, then a deep memory acquisition is taken, and the captured points are displayed to the user for viewing. If a trigger is not received within the predetermined period of time after the stop command is received, then the last acquisition taken at the optimum update rate remains displayed for viewing by the user.
