Subject to change without notice
0 dBV equals 1 Volt (logarithmic scaling of the Y axis). If the
reference symbol is 5.5 cm (div.; typically) above the noise
level and is the current scaling 20dB, the noise level is 110dB
(typically) below 1 Volt.
37.5 Off
The function key “Off“ switches over from FFT to Yt mode and
the FFT menu off.

AUXILIARY INPUT
(BNC connector)
In analog mode this BNC connector serves as an input for
external trigger or Z axis (intensity modulation) input. In digital
mode it can only be used as a external trigger input.
The connector housing is connected to the instrument housing
and thus to safety ground. The ring around the connector is the
probe identification contact, no voltage may be applied here.

PROBE ADJ.
(connector)
The square wave signal from this socket has an amplitude of 0.2
V
pp
and serves for frequency compensation of 10:1 probes. The
signal frequency can be determined in the menu “Utilities“ that
is present after pressing PROBE ADJ-pushbutton
41
.
Further information may be found in the section ”Probe adjust-
ment and use“ in the chapter ”Operation and presettings“.
40
PROBE ADJ
(pushbutton)
Pressing this pushbutton opens the menu “Utilities“.
40.1 COMP.Tester On Off
Component Tester mode (On) is only possible in analog mode
which is automatically set.
In this mode only a shorter trace, “Component Tester“ and
measurement parameter (test voltage and maximum test
current) are displayed. The sockets marked “COMP. TESTER“
serve as inputs.
Pressing the function key “off“ switches back to the last used
operating conditions.
40.2 Calibrator
The function keys 1 kHz and 1 MHz enable the selection of the
square wave signal frequency available at the PROBE ADJ
connector.
40.3 Information
This function key opens the item Utilities Information which
offers information about the oscilloscope.
40.4 USB Stick
If “None“ is displayed, no USB fl ash drive is connected at the
“USB Stick“
42
. After connecting a USB fl ash drive “None“ is
replaced by hints on the submenus Save and Recall that can be
opened by pressing the assigned function keys.
When the menu Utilities is not displayed, it opens automati-
cally when a USB fl ash drive is connected. with the USB Stick
connector
42
.
40.4.1
USB Stick Save
40.4.1.1
Front Panel (current oscilloscope parameters)
The current parameters are saved on the USB fl ash drive by
pressing the function key “Save as SET00000“. Afterwards the
display shows the name of the next memory (e.g. SET00001) in
which parameter can be saved.
40.4.1.2
Screenshot
Screenshot can be saved in bit map format by pressing the
function key “Save as SCR00000“. Afterwards the display shows
the name of the next memory (e.g. SCR00001) in which bit map
data can be saved.
40.4.1.3
Wave
After the selection of “Source“ (channel) and “Type“ (REF = re-
ference memory; CSV (data format) = comma separated value;
ASC (ASCII) or BIN (binary format) the sector “Save as WAV00000
shows the memory name in which the data are stored. After-
wards the display shows the name of the next memory (e.g.
WAV00001) in which wave form data can be saved.
40.4.2
USB Stick Recall
40.4.2.1
Front Panel (stored oscilloscope parameters)
Press “Recall“ if only one parameter set is stored in the USB
fl ash drive.
If more then one parameter set is stored in the USB fl ash drive,
the function key “File“ together with the rotary encoder symbol
are displayed. Pressing “File“ opens a “Selection“ box opens
where different memory place numbers can be selected by aid
of the INTENS knob
2
.
Press the “Recall“ function key to copy the selected signal (wave)
into the selected oscilloscope reference memory.
40.4.2.2
Reference Memory x (rotary encoder symbol)
Press the “Reference“ function key and turn the INTENS knob
2
to select one of 9 oscilloscope reference memories into which
the signal (wave) stored in the USB fl ash drive shall be copied.
If more than one signal (wave) is stored in the USB fl ash drive,
the function key “File“ together with the rotary encoder symbol
