This command generates a trigger immediately and executes a
measurement, regardless of the setting of the trigger mode.
This command is different from :TRIG as the execution of the object
finishes when the measurement (all of the sweep) initiated with this object
is complete. In other words, you can wait for the end of the measurement
using the *OPC object.
If you execute this object when the trigger system is not in the trigger wait
state (trigger event detection state), an error occurs when executed and
the object is ignored.
Examples
Dim Var as Integer
Ana.WriteString ":TRIG:SOUR BUS", True
Ana.WriteString ":INIT1:CONT ON", True
Ana.WriteString ":TRIG:SING", True
Ana.WriteString "*OPC?", True
Var=Ana.ReadNumber
