11.2.3 Memory Management
Memory Management controls how the instrument stores the acquired samples.
Auto: The default acquisition setting. After setting the maximum memory in the Auto mode, the
oscilloscope automatically adjusts the sample rate and memory depth according to the time base. The
adjustment principle is to follow the formula:
Sample rate = number of samples/time of acquisition
Where the time of acquisition is the time corresponding to the full display (i.e. 10 horizontal divisions).
Note:
The maximum memory here is the upper limit of the memory space
allocated by the oscilloscope. The actual sample points are related to the
current time base and may be less than memory depth. The actual sample
points information can be obtained in the timebase descriptor box (see the
section "Timebase and Trigger" for details).
Fixed Sample Rate: The sample rate is fixed as set, and the oscilloscope automatically adjusts
memory depth according to the time base. The time of acquisition is the time corresponding to the full
display (i.e. 10 horizontal divisions).
Fixed Memory: The memory depth is fixed as set, and the oscilloscope automatically adjusts the
sample rate according to the time base. With a small time scale (such as 1 ns/div) the memory depth
is beyond the time of the full display, so it needs to zoom out the acquired frame for viewing the
complete frame in Stop mode.
Note:
When the status is Run, the scope only processes the data on the
display, which means measure, math, decode, search, etc. only analyzes the
data on the display. This is identical to the "Auto" memory management
mode.
