11 .2 References
References are data sets which consist of settings infor-
mation 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 re-
loading, 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 R&S®HMO 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. The top soft menu SOURCE allows
you to use the universal knob in the CURSOR/MENU sec-
tion to select the source for the reference to be saved. You
can select from the activated channels and mathematical
curves. Open the menu to store and load by pressing the
REF key in the VERTICAL section of the control panel.
To import or export instrument settings, you must have a USB
stick connected, otherwise the menu cannot be selected.
