The following equation shows the relations among memory depth, sample rate, and
horizontal time base scale:
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 scale. The unit is s/div.
•
HDivs: indicates the number of grids in the horizontal direction. The unit is div.
•
Therefore, under the same horizontal time base scale, a higher memory depth can
ensure a higher sample rate.
Press
desired memory depth, and then press down the knob to select it. You can also press
Mem Depth continuously or enable the touch screen to select the desired memory
depth. By default, the memory depth is Auto.
•
In single-channel mode, the memory depths available include Auto, 1 Kpts, 10
Kpts, 100 Kpts, 1 Mpts, 10 Mpts, 25 Mpts, 50 Mpts, 100 Mpts, 125 Mpts, 250
Mpts, and 500 Mpts.
•
In dual-channel mode, the memory depths available include Auto, 1 Kpts, 10
Kpts, 100 Kpts, 1 Mpts, 10 Mpts, 25 Mpts, 50 Mpts, 100 Mpts, 125 Mpts, and 250
Mpts.
