This means that when activating the list mode, the system checks whether any hardware
settings are present. If so, the list is started immediately, but if not they are automatically
determined (the list is learnt).
A "Learn List Mode Data" button is available for deliberately activating list learning.
Note: Activating the list mode automatically deactivates all sweeps. During list mode the
frequency and level indications do not display the currently set values.

Mode - List Mode
Selects the cycle mode of the List mode.
"Auto"
Cycle from the beginning to the end of the list with automatic restart at
the beginning. If a different mode was activated prior to the Auto mode,
the cycle continues from the beginning of the list. The duration of a list
step is determined by the set dwell time.
Button "Reset" restarts the list at the starting point.
"Single"
Single cycle from the beginning to the end of the list. If "Single" is
selected, the cycle is not started immediately. The "Execute Single"
button appears under the "Mode" line. The cycle is started with this
button. The duration of a list step is determined by the set dwell time.
Button "Reset" restarts the list at the starting point.
"Step"
Manual, step-by-step processing of the list. Activating "Step" stops the
current list and the cursor moves to the value displayed for "Current
Index". It is now possible to scroll up and down in the list in discrete
steps by varying the index. The duration of a list step is determined by
the time between two index entries.
Button "Reset" restarts the list at the starting point.
"Extern Single"
Single cycle from the beginning to the end of the list as with "Single",
but started by an external trigger.
The external trigger signal is input at the BNC connector INST TRIG.
Button "Reset" restarts the list at the starting point.
"Extern Step"
Step-by-step cycle using the external trigger signal. Each trigger event
starts a single step. The duration of a list step is determined by the time
between two trigger events.
The external trigger signal is input at the BNC connector INST TRIG.
Button "Reset" restarts the list at the starting point.
