SWP ERS (sweep erase)
Sweep erase is used to control when the sweep signal is erased. The choice is ON
(default) or OFF. When the sweep erase is enabled (ON) the sweep signal is
automatically erased before the next sweep signal is provided, and the signal on
the screen is constantly updated. If SWP ERS is disabled, the screen is only erased
if the ERASE direct-function key ( ) is pressed.
To choose when the sweep signal is erased, press the DISP menu key ( )
twice, followed by the E key. With SWP ERS highlighted, rotate the knob to select
ON or OFF.
