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 GUI update for optimum sweep performance espe-
cially with short dwell times (see chapter 5.2.3.4, "Gui Update", on page 132).

Global Trigger/Clock Settings - LF Sweep
Open the Global Trigger/Clock Settings menu. This menu is used among other things for
setting the polarity of the active slope of an applied instrument trigger
In the case of two-path instruments this setting is valid for both paths. It affects the INST
TRIG input (BNC connector at the rear of the instrument, instrument trigger for Path A)
and the INST TRIG B input of the AUX I/O interface at the rear of the instrument, instru-
ment trigger for Path B).
See also .chapter 5.2.3.10, "Global Trigger/Clock/External Input Settings", on page 137
User Marker / AUX I/O - Global Settings
Calls the menu for configuring the AUX I/O and user interfaces (see chapter 5.2.3.12,
"User Marker / AUX I/O Settings", on page 140).
The pin assignment of the AUX I/O interface is shown in the "User Marker / AUX I/O
Configuration" menu; the assignment of the USER pins 2...4 and USER 1 BNC connector
can be changed.
With two-path instruments, the current assignment to the respective path is given in
addition to the pin assignment.
5.5.14 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.
