Figure 7-2: Schematic representation of a signal generated in list mode (global dwell time)
The list mode is especially useful in high-speed measurements with fast changing
frequency and level settings.
Note that the shown diagrams represent the behaviour in theory. In real signal genera-
tion, the instruments usually have a blank time when the frequency or level changes.
Interactions and characteristics of list and sweep mode
●
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 perfor-
mance, especially with short dwell times
