2.27 LIST
Mode
A sequence of predefined frequency and level points is executed in the LIST mode, similar as in a
sweep. Differently from the sweep, however, a list with freely selectable pairs of values (frequency and
level) can be generated. The specified range of the frequency comprises the entire adjustable frequency
range of the instrument. The specified range of the level covers a 20-dB range. If the permissible
variation range is exceeded, the level error increases.
Caution:
After the generation or change of a list in the LIST mode, function LEARN has to be started
to ensure that the new settings are transferred to the hardware (IEC-bus short command:
LIST:LEAR
.

Up to 10 lists can be created. The total amount of possible pairs of values including all lists may
maximally be 2000. I.e., a list may have 2000 entries at the most, or less if several lists have been
created.
Each list is identified by a separate name and selected via this name. A detailed description how to
process the lists can be found in Section 2.2.11, List Editor.

Operating Modes (MODE)
The following LIST-operating modes are available:
AUTO
Run from the beginning to the end of the list with automatic restart at the beginning.
If another mode was activated prior to the AUTO operating mode, continuation is
made from the current index.
IEC/IEEE-bus commands:
:SOUR:FREQ:MODE LIST
:SOUR:LIST:MODE AUTO
:TRIG:LIST:SOUR AUTO
SINGLE
Single run from the beginning to the end of the list. If SINGLE is selected, the run is
not yet started. Function EXECUTE SINGLE LIST to be executed, which can be
used to start the run, is displayed below the MODE line.
IEC/IEEE-bus commands:
:SOUR:FREQ:MODE LIST
:SOUR:LIST:MODE AUTO
:TRIG:LIST:SOUR SING
