To import or export instrument settings, you must
have a USB stick connected, otherwise the menu
cannot be selected.
Pressing the
IMPORT/EXPORT
key by default will copy the se
-
lected settings file. If two USB sticks are connected (front and
back) this will also work between the two USB sticks.
Device settings of an older firmware version can not
be loaded with an actual firmware version.
The menu item
DEFAULT SETT.
also allows you to load the
factory default settings.
10.2 References
References are data sets which consist of settings information
and A/D converter data. These may be stored and reloaded
internally or externally. Data can be reloaded into one of the
4 reference memories (RE1 to RE4) which can also be displayed.
The main feature of references is the fact that all information
(e.g. vertical gain, time base setting, A/D converter data) is
included when saving or reloading, enabling a comparison
between the original signal and its corresponding values.
The soft menu
REFERENCES
only allows you to import or export
references (IMPORT/EXPORT). The transfer of references to
other instruments is possible. The standard menu for the file
manager opens which allows you to copy references between
the internal memory and the external USB stick (description
see Chap. 10.1.).
Fig. 10.5: Loading and storing of references
An additional menu is opened for storing and loading refer
-
ences. Press the REF/BUS key in the VERTICAL section of the
control panel to open a quick menu. The bottom menu key is
divided into RE (reference) and BU (bus). The current setting is
highlighted in white. The soft menu key RE allows you to activate
each of the four possible reference curves “RE1…RE4”. This is
done by pressing the respective soft menu key. The selected
reference will be displayed and highlighted in the quick menu.
If the reference memory is empty, a file dialog opens to load a
reference curve from the internal memory.
Open the menu to store and load by pressing the MENU key in
the VERTICAL section of the control panel. The top soft menu
SOURCE allows you to use the universal knob to select the
source for the reference to be saved. You can select from the
activated channels and mathematical curves. Press the soft
menu key DISPLAY to display the selected reference curve or
to update the current reference curve.
To load a reference from a
USB stick or the internal memory,
open the soft menu
LOAD
. This shows a window displaying the
internally stored references. You can select the desired target
reference curve in the top menu item and by pressing LOAD in
the file manager. To complete loading and displaying the refer-
ence, press LOAD in the file manager menu again. To save a
reference, press the
SAVE
key, determine the source, storage
location, file name and curve, and press the soft menu key
SAVE
(with the disk icon). The FILE NAME can be changed or
adjusted to the corresponding setting (REF ist the default label).
You can use the soft menu key COMMENT to enter a comment
which will be displayed in the file manager footer once a file
has been selected.
10.3 Traces
In addition to references, you can also store A/D converter data.
A maximum of 24,000 measured samples (expanded display
memory) can be stored on a USB stick. Curves can only be stored
to externally connected USB sticks (not internally).
The maximum of 24,000 measured value points can
only be read out with the maximum sampling rate
(ACQUIRE menu). For the AUTOMATIC setting (re-
peat rate), the maximum amount of measured value
points is limited to 6,000 (default setting).
The soft menu STORAGE allows you to use the USB connection
on the front or back of the instrument as storage location. Se
-
lecting the respective storage location is possible when a USB
stick has been recognized. If a
USB stick is connected, you can
also change, create or delete directories. Use the soft menu key
SORT ENTRIES
to sort several settings files by name, type, size
or date. Press
ACCEPT DIR.
to confirm the target directory and
you will automatically return to the curve main menu.
Fig. 10.6: Menu for storing curves
You can open a selection window by pressing the soft menu
key FORMAT to determine the file format. The
universal knob
allows you to select the desired format. You can choose from
the following formats:
BIN
A binary file may contain any type of Byte value. The captured
curve data will be stored without any time information.
CSV (Comma Separated Values):
In CSV files, curve data is stored in table format. Each table row
is separated by a comma.
