4.3.3.1 Comparison of Record Modes
In all record modes, the sampling rate used to write to the acquisition memory is the
same. In "STOP" mode, it is also possible to change menu items. Changing the record
mode does not impact the current memory depth but the amount of displayed data is
adjusted. Peak detection is also activated in "STOP" mode. If the time base allows of
the display of each sample point, all three settings behave identically (except used
memory depth and signal update rate). Advantages and disadvantages of the record
modes are listed in
Table 4-1 .
The record mode menu replaces the adjustable memory depth, a standard for other
oscilloscopes. An adjustable memory depth requires that users understand the relation
between memory depth, time base and sampling rate and to evaluate advantages and
disadvantages. With the record mode menu, the oscilloscope always captures signals
with the maximum sampling rate. Zoom in and zoom out in stop mode is always possi-
ble.
