7.1 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.
If the dwell time in sweep or list mode is too short or external trigger signals come too
fast, the signal generation delays. As the delay increases, the R&S SMA100B signals
an overrun, or even stops sweep or list mode signal generation, if the delay gets too
long.
The instrument diplays corresponding error messages.
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-
vating the mode and the generation of the signal when a trigger event occurs. For each
mode, the relevant parameters and settings are briefly explained.
Each "Sweep" and "List" mode dialog provides also a "Reset" function that sets the sig-
nal to the initial value or the beginning of the list. Depending on the selected trigger
mode, the signal generation proceeds accordingly.
The naming of the selection parameters in manual control (GUI) sometimes deviates
from the naming in the remote-control commands. In addition, the value names of the
selection parameters used in the signal generator partly differ from the SCPI syntax.
The instrument accepts all value names.
The correlation between the manual control and the corresponding remote control
commands, including the SCPI conform syntax are explained for each mode (see the
cross-reference tables).
