3.
Shift the percentage of the display that is occupied by
the main sweep by adjusting the DELAY TIME
POSition control. Counterclockwise rotation causes
more of the display to be occupied by the main sweep
and clockwise rotation causes more of the display to
be occupied by the delayed sweep.
4.
Set the Sweep Mode switch to the DELAY position
to display only the magnified delayed sweep portion
of the display.
NOTE
In order to obtain meaningful results with
delayed sweep, the DELAY Time Base
control must set be set to a faster sweep
speed than the MAIN Time Base control.
Because of this, the oscilloscope automat-
ically prevents (electrically) the DELAY
Time Base from being set to a slower
sweep speed than the MAIN Time Base.
For example, if the MAIN Time Base is set
to 0.1 ms/div, the slowest possible DELAY
Time Base sweep speed is also 0.1 ms/div,
even if the control is set slower.
