Stop Acquisition: When the scope is acquiring waveforms, the waveforms are in
live status; when acquisition is stopped, a frozen waveform will be displayed. The
position and scale can still be adjusted by vertical control and horizontal control.
Key Points
Real-time Sampling:
VS5000 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:
Known as Repetitive sampling to 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 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.
