9.2.2 Reference Display
STOP
Attention!
Switching the ”Reference Display“ ”On“ is not
possible if channel 3 and 4 are switched on.
The display of reference signals automatically
switches previously displayed mathematic
signal(s) off and vice versa.
9.2.2.1 RE x, On Off, associated settings
When in this submenu using the INTENS knob will allow
selection of 2 reference signals which can then be displayed
alongside with 2 input signals.
9.2.2.2 RE x
After calling this function the memory location can be selected
with the INTENS knob
. (RE 1 to 9)
9.2.2.3 On Off
With the pushbutton on/off control is possible. When the
contents of the reference memory are displayed, the memory
number is indicated with RE x (x = 1 to 9) at the right hand
screen side. Switching to ”on“ will produce another menu item
(”Assoc.Set“).
STOP
Please note:
If both reference displays are ”on“ and if both
memory locations are identical (e.g. RE1, RE1) the
signal will be displayed twice on the same spot.
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, Germ-
an, 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
determined. 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
sufficiently.
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.
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 automatically 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.
