MDepth ≥ SRate x TSCale x HDivs
MDepth
indicates the memory depth. The unit is pts.
SRate
indicates the sample rate. The unit is Sa/s.
TSCale
indicates the horizontal time base. The unit is s/div.
HDivs
indicates the number of grids in the horizontal direction. The unit is div.
Therefore, with the same horizontal time base, a higher memory depth can ensure a
higher sample rate.
In Horizontal menu, click or tap the Mem Depth drop-down button to select the
memory depth. The default setting is "10k". The selected memory depth value is
displayed in the acquisition label ("A" icon) at the top of the screen.
Memory
Depth
When only one of the channels is enabled, the memory depths available include
Auto, 1 kpts, 10 kpts, 100 kpts, 1 Mpts, 10 Mpts, and 25 Mpts.
When two of the channels are enabled, the memory depths available include
Auto, 1 kpts, 10 kpts, 100 kpts, 1 Mpts, and 10 Mpts.
When three channels or all four channels are enabled (only available for four-
channel models), the memory depths available include Auto, 1 kpts, 10 kpts, 100
kpts, and 1 Mpts.
TIP
In "Auto" mode, the oscilloscope selects the memory depth automatically according to
the current sample rate.
When
Acquisition Mode
is set to "Average", the maximum memory depth available is 10
Mpts in single channel mode and 1 Mpts in half channels mode/all channels mode.
7.5 Horizontal Expansion Reference
This function allows you to set the position that the waveform on the display is
referenced to when it is horizontally expanded or compressed when the horizontal
time base is adjusted. In the
Horizontal menu, click or tap the Expand drop-down
button to select the reference position. Available options include Center (default),
Left, Right, Trigger, and User.
Center: when the horizontal time base is modified, the waveform will be
expanded or compressed horizontally relative to the center of the display.
