Subject to change without notice
STOP
Please note:
This sensitivity selection is always active, e.g. also,
if CH2 only was chosen. In that case CH1 may be
used as trigger source.
12.2 Variable control
Select this function with the CH1 VAR pushbutton
27
to display
the “CH1” menu and press the function key “Variable On Off”
so that “On” is activated. The CH1 VAR pushbutton will light up,
indicating that the VOLTS/DIV VAR knob
12
now has the function
of a variable control. Using the VOLTS/DIV VAR control knob the
sensitivity can be changed from 1 mV/cm to
>
20 V/cm; the range
is (automatic probe) factor or (manual probe setting) dependent
and thus the signal display height.
Uncalibrated the readout will add a ”
>
“ to the sensitivity in-
dication (”CH1
>
5mV..“) in order to show that the sensitivity is
now uncalibrated. The results of cursor measurements will be
fl agged accordingly.
After resetting “Variable” to “Off”, the CH1 VAR pushbutton
27
will extinguish, the defl ection coeffi cient is calibrated and the
VOLTS/DIV VAR knob
12
switches in 1-2-5 sequence.
13
VOLTS/DIV VAR knob
This double function control belongs to CH2.
13.1 Selection of vertical sensitivity
Provided CH2 VAR pushbutton
29
is not illuminated the sensi-
tivity will be calibrated. Turning the control CCW will decrease,
turning it CW will increase the sensitivity. The sensitivities can
be selected from 1 mV/cm to 20 V/cm in a 1-2-5 sequence; the
range is (automatic probe) factor or (manual probe setting) de-
pendent. The readout will show the sensitivity (e.g. ”CH2:5mV..“).
Depending on the sensitivity the signal will be displayed with
smaller or greater amplitude.

AUTO MEASURE
(pushbutton)
In XY mode AUTO MEASURE can not be called.
If the AUTO MEASURE function is switched off, pressing this
pushbuttones it on and displays the measuring results in the
9.3. CURSOR position
The POSITION 1 control will function as Y position control
of the cursors with CURSOR display on after pressing the
CH1/2–CURSOR–TRACE SEP-pushbutton
11
and ”Cursors“,
“Aux(iliary) Cursors” or ”Cur. Track“ is chosen. The pushbutton
will light up in blue.
STOP
Please note:
The function ”Cur. Track“ is only available if two
cursors are indeed displayed, then both cursors
can be moved simultaneously (tracking) without a
change of their respective positions.
10
POSITION 2
(knob)
Also this control may assume diverse functions dependent on
the operating mode, the function selected via the CH1/2–CUR-
SOR–TRACE SEP-pushbutton
11
and the menu item activated.
10.1.
Y-position CH2
POSITION 2 will function as Y-position control of CH2 in Yt
mode and if the CH1/2–CURSOR–TRACE SEP-pushbutton
11
is not illuminated.
10.2 Y-position of CH2 in XY mode
POSITION 2 will function as the Y-position control of CH2 in XY
mode provided the CH1/2–CURSOR–TRACE SEP-pushbutton
11
is not illuminated.
10.3 Y-position of cursors
The POSITION 2 control will function as Y position control of the
cursors if the following conditions are met: The cursors must be
activated (CURSOR MEASURE pushbutton
4
) and after pressing
the CH1/2–CURSOR–TRACE SEP-pushbutton
11
”Cursors“,
“Aux(iliary) Cursors” or ”Cur. Track“ is selected. The pushbutton
will light up blue.
STOP
Note:
The function Cur. Track (cursor tracking) is only
available if 2 cursors are on display. The cursors
will then be moved simultaneously (tracking) wit-
hout changing their respective positions.
11
CH1/2–CURSOR–TRACE SEP-pushbutton
This pushbutton calls a menu which allows to select the func-
tions of the controls POSITION 1
9
and POSITION 2
10
.
The pushbutton will signal the function activated corresponding
to the front panel labelling:
dark:
Y-position CH1 and CH2.
blue:
Y-position of cursors.
green:
Y-position of time base B display of signal(s)
12
VOLTS/DIV VAR
(knob)
This knob is a double function CH1 control.
12.1 Selection of vertical sensitivity
Provided CH1 VAR pushbutton
27
is not illuminated the sensi-
tivity will be calibrated. Turning the control CCW will decrease,
turning it CW will increase the sensitivity. 1 mV/cm to 20 V/cm
can be selected in a 1-2-5 sequence; the range is (automatic
probe) factor or (manual probe setting) dependent. The rea-
dout will display the calibrated sensitivity (e.g. ”CH1: 5mV..“).
Depending on the sensitivity selection the signal will be shown
with smaller or greater amplitude.
