limits available under delayed sweep, see the chapter “Performance

Varying the Time/Div Setting
When you vary the Time/Div setting during Run mode, remember that the
sample period may also be adjusted. If, for example, you rapidly change the
Time/Div setting to a higher value (slower sweep speed), the sample period is
also lengthened, and it will take longer to fill acquisition memory. The
previous acquisition is first redrawn on the screen at the new Time/Div
setting before starting a new acquisition. Thus, there may be a short delay
before a complete screen of data is displayed.
