The "Dwell Time" set by the user is used as the step time of the sweep. The effective
net dwell time is shorter, reduced by the setting time. This setting time may be greater
than the time specified in the data sheet.
Note:
It is recommended to switch off the display update for optimum sweep performance
especially with short dwell times (see Chapter 5.2.3.7, "Display Update", on page 132).

5.5.14.4 List Mode
Similar to a sweep, a series of previously defined frequency and level points is pro-
cessed 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.
Interactions between List mode and other operating modes or settings
●
List mode and sweeps can not be activated simultaneously, they deactivate each
other.
●
Activating the list mode instantly disables NRP-Z Level Control.
A running list mode blocks "NRP-Z Level Control". It can not be activated
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
frequency 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
