5.9 Automatic Settings for Manual Selection of a Measure-
ment Mode
When the measurement mode of a sensor is manually selected ("Sensor"
→
"Mode"),
automatic settings are made for the trigger system and timing, which cannot be changed
by manual control. This considerably simplifies operation. These settings are not changed
when the measurement mode is selected by remote control (
SENSe:FUNCtion
) and
have to be set to the desired value by appropriate SCPI commands.
The following table lists the respective setting capabilities and the values that are auto-
matically set in manual control.
