This persistence works best with high values of N, typically values of 50

through 100. In this mode, no softkeys can be pressed until after EXIT GRAD-

ING is pressed.

Monochrome Grading Persistence

Monochrome grading persistence ( MONO GRADING) works just like color

grading except that a given pixel increases in intensity instead of color each

time a dot falls on it. There are 15 different levels of intensity. In this mode,

EXIT GRADING must be used to return to normal instrument operation.

a Apply persistence by pressing:

Traces, persist, PERSIST SWEEPS

Enter one of the following:

• If variable persistence will be used, enter the number of sweeps taken before

a trace decrements in brightness.

• If grading persistence will be used, enter the number of sweeps taken until

the grading display is stopped.

b Press one of the four top right-side softkeys to select the persistence mode.

c Pressing OFF can stop INFINIT and VARIABLE persistence at any time.
