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.
•
When only one of the four channels (CH1-CH4) is enabled, the memory depths
available include Auto, 1 kpts, 10 kpts, 100 kpts, 1 Mpts, 10 Mpts, 25 Mpts, and
50 Mpts.
•
When two of the four channels (CH1-CH4) are enabled, the memory depths
available include Auto, 1 kpts, 10 kpts, 100 kpts, 1 Mpts, 10 Mpts, and 25 Mpts.
•
When three channels or all four channels are enabled, the memory depths
available include Auto, 1 kpts, 10 kpts, 100 kpts, 1 Mpts, and 10 Mpts.
TIP
•
In "Auto" mode, the oscilloscope selects the memory depth automatically according to
the current sample rate.
Acquisition Mode
•
When
Mpts in single channel mode and 1 Mpts in half channels mode/all channels mode.
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.
•
Left: when the horizontal time base is modified, the waveform will be expanded
or compressed horizontally relative to the leftmost position of the display.
