5.4.15 List Mode
Similar to a sweep, a series of previously defined frequency and level points is processed
in List mode. In contrast to a sweep, however, a list with freely selectable value pairs
(frequency and level) can be created. The value range for frequency and level covers the
entire configurable value range of the instrument.
List mode and sweeps can not be activated simultaneously, they deactivate each other.
The lists can be created in the "List Editor". Each list is stored in its own file with the
predefined file extension
*.lsw
. The name of the list file can be freely selected. The files
are loaded from the "Lists..." file manager. Externally created tables with pairs of fre-
quency and level values can be converted into List files using the import function. The
external files must have the file extension
*.txt
or
*.csv
. These file formats are pro-
vided e.g. by the Microsoft
®
Excel program. The separators for table columns and for
decimal floating-point numerals can be set. In addition, internally created List data can
be exported into ASCII files using the export function.
The necessary hardware settings are calculated the first time a list is processed. With
long dwell times, this calculation can be performed while the list is being processed; the
entered dwell times are observed. With very short dwell times, calculation of the hardware
settings increases the dwell time for the initial processing cycle; the entered value is only
observed from the second processing cycle onwards. In this case a message appears to
inform the user that there is a deviation between the current and set dwell times. No
further calculations are required after the first run through a list. The current dwell times
will definitely no longer deviate from the set dwell times.
The list is processed from the beginning to the end of the list (modes "Auto", ("Exter-
nal") "Single", ("External") "Step").
