Subject to change without notice
pushbutton underneath the triangle symbols. Briefly press
the pushbutton underneath “SET” to store the last
instrument setting and return from menu display to
previous mode. If the SAVE function was called inad-
vertently, it can be switched off with “Esc”.
Switching the instrument off automatically stores the
current settings in memory location 9 (PWR OFF = Power
Off), with the effect that different settings previously stored
in this location get lost. To prevent this, RECALL 9 before
switching the instrument off.
RECALL:
Briefly pressing calls the RECALL menu. You can select
the required memory location using a “triangle” push-
button. Recall the previously stored instrument settings
by briefly pressing the “SET” pushbutton or briefly press
“Esc” if the function was called inadvertently.
RECALL also offers the item DEFAULTS, which covers all
functions.
The setting controls and LED’s for the Y amplifiers,
modes, triggering and time base are located under-
neath the sector of the front panel described above.
(6) Y-POS/CURS. I
Control knob with several functions.
This knob allows position control of channel I trace or
CURSOR line(s). Briefly pressing the CURSOR POS
pushbutton (7) selects the function. If the CURSOR line(s)
are not displayed the CURS. I function is not selectable.
Y-POS:
The
vertical trace position
of channel I can be set with
this control knob, if the CURSOR POS (7) LED isn’t lit. In
addition (“add”) mode both (
Y-POS/CURS. I (6)
and
Y POS/
CURS. II
) control knobs are active. If the instrument is set

knob must be used for horizontal positioning.
DC voltage measurement:
If no signal is applied at the
INPUT CHI (25)
, the vertical trace
position represents 0 Volt. This is the case if
INPUT CHI (25)
or in addition
(ADD)
mode, both
INPUT CHI (25)
and
INPUT
CHII (28)
, are set to
GND
(ground) (26) (29) and automatic
triggering
(AT (9))
is present to make the trace visible.
The trace can then be set to the vertical position best
suited for the following
DC
voltage measurement. After

DC signal applied at the input changes the
trace position in vertical direction. The
DC
voltage then
can be determined by taking the deflection coefficient,
the probe factor and the trace position change with respect
to the previous 0 Volt position into account.
”0 Volt” Symbol:
The READOUT indicates the “0 Volt” trace position of
channel I by a ”

mode. When Y position is
used, this symbol changes to an “arrow” symbol pointing
outside the graticule just before the trace goes outside
the graticule limits
If addition mode (“add”) is present just one ”

is visible.
In XY mode the “0 Volt” trace position for channel I (X) and
channel II (Y) is symbolised by “triangle” symbols at the
right graticule border (Y) and above the Y deflection
coefficient display. The “triangle” symbol(s) point(s)
outside the graticule when the “0 Volt” trace position is
outside the graticule.
CURS.I:
The CURSOR lines marked by the symbol “I” can be shifted
by the
Y-POS/CURS. I
control knob, if the CURSOR POS
LED (7) is lit.
STORAGE MODE ONLY
In contrast to analog mode the Y-POS/CURS.I (6) knob must
be used for X position shift in XY mode and the X-POS.
knob is disabled.
The Y-POS/CURS.I (6) knob can also be used for shifting a
signal position although it is stored by HOLD (“hld“).
If a REFERENCE or MATH (mathematic) signal is displayed
and the M/R [38] LED is lit, the Y-POS/CURS.I (6) knob serves
as a MATHEMATIC or REFERENCE position control.
(7) CURSOR POS
Pushbutton and LED.
Briefly pressing this pushbutton determines the function
of the Y POS/CURS.I (6) and Y POS/CURS.II (8) controls.
If the CUR LED is not lit the Y position control function is
active.
Provided that the CURSOR lines are activated, the LED
can be switched on by briefly pressing the CURSOR POS
pushbutton. Then the controls (6) and (8) are switched
over from Y position to CURSOR position control (CURS.I
(6) and CURS.II (8)). Briefly pressing this pushbutton once
again switches back to the Y position control function.
STORAGE MODE ONLY
The CUR LED extinguishes after a REFERENCE or MATH
(mathematic) signal is displayed and the M/R LED is switched
on by the MATH/REF POS [38] pushbutton. Under these
conditions the Y-POS/CURS.I (6) knob serves as a REFERENCE
or MATH (mathematic) signal position control, while Y-POS/
CURS.II (8) affects the channel II signal if present.
(8) Y POS/CURS. II
Control knob with two functions.
This knob enables position control of channel II trace or
CURSOR line(s). Briefly pressing the CURSOR POS
pushbutton (7) selects the function. If the CURSOR line(s)
are not displayed the CURS. I function is not selectable.
