14.2 Acquisition Setup
14.2.1 Overview
Touch Acquire Menu on the quick menu of the timebase settings, or press the
Acquire button on the front panel, or touch the menu bar Acquire>Menu to recall
the Acquire dialog box on the right side.
A. Select the acquisition mode
(Normal/Peak/Average/Eres)
B. Select the maximum memory depth
C. Select the interpolation mode
D. Select the Acq mode
Acquisition: See the section "Acquisition" for details.
Memory Depth: The maximum memory depth that can be supported.
According to the formula "acquisition time = sample points x sample interval",
setting a larger memory depth can achieve a higher sample rate for a given
timebase, but more samples require more processing time, degrading the
waveform update rate. With 250 Mpts memory depth, SDS5000X can still run
at full sample rate (5 GSa/s) even when set to the 5 ms/div timebase.
Note: The memory depth here is the upper limit of the memory space allocated
by the oscilloscope. The actual sample points is related to the current timebase
