Key Points 
Real-time Sampling: 
DS1000B has Real-time sampling rate up to 2GSa/s. At the time base 50ns or 
faster, the oscilloscopes use the sine(x)/x interpolation to expand the horizontal 
time
 base. 
 
Equivalent sampling
:  
Known as Repetitive sampling to get up to 20ps of horizontal resolution (equivalent 
50
Gsa/s). This mode is good for observing repetitive signals, and it is not 
recommended
 for single-shot or pulse. 
 
Normal: 
 
Oscilloscope acquires signal by equal time interval. 
 
Average Acquisition
:  
Apply averaging to your signal to remove uncorrelated noise and improve 
measurement accuracy. Reduces
  random or uncorrelated noise in the signal 
display. The averaged waveform is a running average over a specified number of 
acquisitions from 2 to 256. 
 
 
Peak Detect
:  
Peak Detect mode captures the maximum and minimum values of a signal, and 
finds highest and lowest record points over many acquisitions.
