9.2.2.4
Associated settings
If the pushbutton labelled ”Assoc.Set.“ is depressed the readout
will show all oscilloscope settings which were loaded into the
reference together with the signal. The signal parameters may
be recalled.
SETTINGS
Pressing this pushbutton will open the SETTINGS menu which
offers the following submenus:
10.1 Language
In thus submenu the language can be selected: English, Ger-
man, French are available for choice.
10.2 Misc (Miscellaneous)
10.2.1
Contr.Beep On Off
Switches the acoustical signal on or off, which informs about
CW or CCW positions of knobs.
10.2.2
Error Beep On Off
Will turn the acoustical error signal on or off.
10.2.3
Quick Start On Off
In off the HAMEG logo, the type and the version number will not
be shown, the instrument will be ready immediately.
10.2.4
Menu Off time
With the INTENS knob
the time of menu display may be de-
termined. EXIT MENU will terminate a menu on the spot.
In ”Man.“ mode the menu can be left:
– by pressing EXIT MENU.
– by pressing another pushbutton.
– by pressing the same pushbutton again with which the menu
was called.
10.3 Interface
This menu shows the interface parameters which can be
selected as usual.
10.4 Display
This submenu offers several modes of display:
10.4.1
Dots
In this mode the samples are shown as what they are, i.e. dots
(points). This representation is valuable for judging whether
enough samples were gathered in order to reconstruct a signal
suffi ciently.
10.4.2
Vectors
In this mode the sampling points are interconnected by drawing
straight lines. If there are only few samples sin x/x interpolation
is used to ”create“ intermediate points which are then joined
by straight lines.
C o n t r o l s a n d R e a d o u t
10.4.3
Optimum display
In this mode minimum and maximum signal values acquired
are taken into consideration and displayed in Vectors mode.
This makes sense as up to 1 MByte samples may be acquired,
but only up to 2 KBytes per channel can be displayed, hence
possibly min or max values may not be shown. Otherwise the
display is as described above.
AUTOSET
Choosing AUTOSET will cause an automatic instrument setting,
dependent upon the signal proper which selects positions, signal
amplitude and time base for a reasonable display. The choice
of analog or DSO mode will not be affected. In component test
mode (available only in analog mode), XY mode, or ADD auto-
matically dual channel mode will be selected. If dual channel
or CH1 or CH2 were previously chosen this will remain.
The DSO modes Roll, Envelope or Average will be changed to
refresh mode.
AUTOSET will further set the intensity to an average value if it
was set too low. If a menu was opened it will be turned off by
AUTOSET. During the display of HELP texts AUTOSET is not
available.
HELP
Pressing the HELP pushbutton will turn the signal display off
and display the help text.
If a menu was opened the help text will refer to this menu resp.
to the special menu or submenu option selected. If a knob is
moved another help text referring to this knob will appear. Press
HELP again to deactivate the text.
POSITION 1 (knob)
This knob can assume various functions which depend upon the
operating mode, the functions selected with the CH1/2–CUR-
SOR–MA/REF–ZOOM-pushbutton
and the menu option
selected.
13.1 Y position
13.1.1
Y position CH1 (Analog and DSO modes)
POSITION 1 will set the Y position of CH1 provided there is YT
mode and the pushbutton CH1/2–CURSOR–MA/REF–ZOOM-
pushbutton
is not illuminated.
13.1.2
REF (reference) signal position (DSO mode only)
The POSITION 1 control functions as the position control for
the signals stored in the reference memory if these conditions
are fulfi lled:
