User’s Guide for DS1000 Series

Key Points

Real-time Sampling:

DS1000 has Real-time sampling rate up to 400MSa/s. At the time base 50ns or

faster, the oscilloscopes use the sine(x)/x interpolation to expand the horizontal

time base.

Equivalent sampling:

Also known as Repetitive sampling. In this mode, you can get up to 40 ps of

horizontal resolution (equivalent 25Gsa/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. Finds

highest and lowest record points over many acquisitions.
