Figure 5-2: Schematic representation of a signal generated in list mode (global dwell time)
This mode is especially useful in high-speed measurements with fast changing fre-
quency and level settings.
Interactions and characteristics
●
Activating the list mode automatically deactivates all RF and LF sweeps and vice
versa.
●
In list processing mode, the frequency and level display in the status bar is dis-
abled.
●
The sweep modes only work with a
global
dwell time, that means the time intervals
are constant during signal generation.
●
If you want to hold a running sweep at a specific frequency or level value, enter the
value in the status bar. The sweep stops immediately.
●
We recommend that you switch off the display update for optimum sweep perform-
ance, especially with short dwell times

5.1 Signal Generation and Triggering in the Sweep and
List Modes
In both operating modes "List" and "Sweep", triggering and signal generation follow the
same principle. The instrument generates the signal continuously (that means trig-
gered automatically) or in individual steps (controlled manually by an internal or exter-
nal trigger signal).
The instrument expects the trigger signal at the INST TRIG connector.
The figures in this section give an overview on the signal generation in the sweep and
list modes and the appropriate triggering. The figures show the signal state after acti-
