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.
