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
50Gsa/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.
