position is then selected, it is possible that the

input signal may no longer match the display. In

this case (square-wave signals), linear interpol-

ation (ITPL LIN) is ideal for display purposes.

13.6 AMAG = ALT MAG mode

Keep pressing the MENU button until "AMAG

OFF" (or AMAG ON) appears at the top edge of

the screen in the middle. In this mode the

SELECT button can only be used to make a set-

ting if the Hold key has previously been pressed.

13.7 Go-NoGo mode (signal assessment)

Keep pressing the MENU button until "G-NG =>

XH OH" appears at the top of the screen in the

middle. With this function, the SELECT button

can be used to toggle between XH= Comparison

and OH = Hold.

G - N G => X H O H

(14) X-Y mode

The procedure to make the settings for the X-Y

function in storage mode is as follows:

a) Set the Vertical switch to the DUAL position

b) Press the HOLD button in order to pause sam-

pling. Both input signals (X = CH1 and Y =

CH2) continue to be displayed.

c) turn the Time/div switch to the right-hand

stop in the case of the OS-3020 D or press the

X-Y button in the "HORIZ DISP" panel on the

OS-3060 D.

Note:

If the brightness is too high, reduce the intens-

ity because otherwise this will damage the

sensitive internal coating of the CRT screen and

the signal could be permanently burnt into the

coating.

If one of these two functions (XH or OH) was sel-

ected, the basic value = 0.4 div must be set by

pressing the RECALL button once. If a higher

value is required, keep the SELECT button pres-

sed until the desired value is reached.

0.4 div: the assessment area covers ±0.4 div

0.8 div: the assessment area covers ±0.8 div

1.2 div: the assessment area covers ±1.2 div

13.8 Header text line at top edge of screen with-

out MENU button

Assuming that all the necessary settings have

been made and the MENU button is no longer

required, keep this button pressed until the LED

under the button cap goes out. The header text

line at the top edge of the screen (right-hand

half) might look as follows:

If this field contains "SM",

smoothing is switched on,

if it is blank, SM is off

N O R M A V 1 6 S A S M

EQUIV in the range from 0.2 µs/div (OS-3060 D: 0.1 µs/div) to 2 µs/div

NORM in the range from 5 µs/div to 2 ms/div

ROLL in the range from 1 ms/div to 0.2 s/div or 20 s/div (in X100 roll mode)

If this line is blank, averaging is switched off;

in this case AV 16 = 16 passes for one display
