Abstract: A test system 100 that can accept a plurality of plug-in electronic cards in Xi Slots 126 or PXI slots 134 is described. The test or source measure switching system 100 includes a sequencer or sequence engine 130 which is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequencer 130 is sequential and deterministic to approximately 10 microsecond resolution. The sequencer 130 includes a trigger router which can be a fully configurable trigger input and trigger output routing matrix. Every trigger input can be configured via several detection modes such as active high, active low, level high and level low. Also, trigger outputs can be configured to be triggered on single, multiple or auto triggers if set.

Abstract: A test system 100 that can accept a plurality of plug-in electronic cards in Xi Slots 126 or PXI slots 134 is described. The test or source measure switching system 100 includes a sequencer or sequence engine 130 which is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequencer 130 is sequential and deterministic to approximately ten microsecond resolution.

Abstract: A method and computer program product with encoded instructions provides for repeatedly making data backups for files by making a series of snapshots of file storage volumes containing the files. The method and computer product further provide for determining that a malware attack has occurred, identifying corrupted files and, for each corrupted file, scanning the series of snapshots to identify an uncorrupted version of the file. Each corrupted file is restored to an uncorrupted version thereof. An event log contains write events and snapshot creation events corresponding to creation of each of the snapshots. A forensic scan scans the event log to determine modifying writes made by the corrupted files and which modified further files. The further files are restored to unmodified versions thereof. A list of at-risk files includes the corrupted files and the further files and the forensic scan is repeated on the at-risk files.
