Fig. 9c Display of time base B

2.2.10 Storage mode

Storage mode functions as follows:

(1) "NORM" mode

a) Press the "STORAGE" button in the "STO-

RAGE MODE" panel.

b) "NORM" appears at the top edge of the

screen in the middle and the displayed signal

that is to be stored is then shown in the "real-

time" display.

c) All subsequent sweeps/displays are in slow

motion. If the Time/div switch is set to 0.1

µs/div, roughly 2 to 3 s elapses until a new

trace is painted and triggered.

d) If the Time/div switch is set to between 0.2

µs/div (in single-trace mode 5 µs/div) and 0.2

s/div (OS-3060 D: 0.1 µs/div to 0.2 s/div),

successive signal waveforms can be continu-

ously stored.

e) The "HOLD" button can be used to pause the

display, i.e. the signal is frozen in NORM

mode.

(2) EQUIV mode (equivalent)

If the Time/div switch for time base A is set to

between 0.2 µs/div and 2 µs/div (OS-3060: bet-

ween 0.1 µs/div and 2 µs/div), "EQUIV" (stands

for Equivalent) appears instead of NORM at the

top edge of the screen in the middle.

a) In this mode it is not possible to display the

left-hand end of the signal waveform (rising

or falling edge); the second cycle of the signal

must therefore be used for measurement pur-

poses.

b) Roughly 5 s elapse before a signal having a

frequency of less than 1 kHz is stored.

(3) ROLL mode

The spot is slowly ”painted” from left to right.

This mode is especially suitable for signal wave-

forms having a frequency of less than roughly

100 Hz. Just press the "HOLD" button in order to

pause Roll mode.

ROLL MODE display

The signal display "rolls" from the right-hand

edge of the screen to the left. Sampling takes

place from right to left, i.e. signal changes are

ﬁrst apparent at the right-hand edge of the

screen. Note the following ﬁgure.
