Key Points: 
Real-time Sampling:  
DS1000B has Real-time sampling rate up to 2GSa/s. At the time base 20ns 
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 50Gsa/s). This mode is good for observing repetitive signals, 
and it is not recommended for single-shot or pulse. 
 
Normal Acquisition:   
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.
