SAMPLINGMODE S

Dependingonyourtimebase,thefollowingsamplingmodesareavailable:

WaveStreamMode ‐ Thisfastviewingmodeprovidesbrightness‐

gradedintensitywithadecaytimesimilartotheactionofphosphor

onananalogscreen.WaveStreammodeoperatesatupto10GS/s

withanupdaterateupto8000waveforms/secondforbetter

captureofhigherfrequencyabnormalevents.

RealTimeMode ‐ Asingle‐shot(realtime)acquisitionisaseriesof

digitizedvoltagevaluessampledontheinputsignalatauniform

rate.

SequenceMode ‐ Insequencemode,thecompletewaveform

consistsofanumberoffixed‐sizesegmentsacquiredinsingle‐shot

mode

RollMode‐Thismodeisinvokedautomaticallyforslowacquisitions

whenthetimeperdivisionis200ms/divorgreater.Rollmode

samplesat2MS/s(dependingonmemoryavailability).
