The SnapShot key in PC-sam causes storage of the last 36 seconds of monitor data. All data transmitted to the PC during the 36 second interval is stored with a time resolution of order 0.5 msec.
SnapShot data files are viewed with SAII's SnapView program. Options exist to allow the entire file to be played back or to view the last few seconds of data. Most features available in PC-sam are also available in SnapView. For example the display configuration can be modified, sweep rates and amplitudes can be adjusted while viewing the files and many of the keys are active to display windows with associated parameter values.
