Measurement system that stores samples acquired during a time window that includes a trigger event and during a subsequent user-specified time window

A non-transitory computer-readable medium having a computer program stored thereon for performing a trigger data acquisition algorithm, the program comprising:

• a first code segment for causing a memory controller to write digital data samples to a memory;
• a second code segment that processes the digital data samples to determine whether a trigger event has occurred;
• a third code segment, wherein if the second code segment determines that a trigger event has occurred, the third code segment causes the memory controller to continue writing digital data samples to the memory until a preselected number of digital data samples acquired during a first time window that includes the trigger event have been written to the memory;
• a fourth code segment, wherein after the third code segment has caused the memory controller to write the preselected number of digital data samples acquired during the first window of time to the memory, the fourth code segment prevents the memory controller from writing digital data samples acquired after the end of the first window of time and before a beginning of a second time window to the memory, wherein the second window of time is subsequent in time to the first window of time and is specified by the user;
• and
• a fifth code segment, the fifth code segment causing the memory controller to resume writing acquired digital data samples to the memory during the second window of time, the fifth code segment causing a preselected number of digital data signals to be written to the memory during the second window of time.
