Abstract: An automatic save and recall system and method for use in signal measurement systems that acquire and store signal data in accordance with a trigger specification, including generally a trigger definition and trigger control parameters (“trigger controls”). The present invention automatically stores in memory (“saves”) trigger-related data that includes, for example, a current trigger definition and other specified portions of a trigger specification (“saved trigger specifications”) without an explicit operator request. A plurality of such saved trigger specifications are subsequently available for retrieval from memory (“recall”). This enables an operator to easily return to a previous version of a trigger definition should the operator determine that a current trigger definition is undesirable. The automatic storing of trigger specifications (or portions thereof) may occur in response to one or more predetermined event(s).
