Open and close the average option for the measurement result. It can set the average number. When
the Avg Number is set to off, the column title "Average" in numerical results view will be changed to

to open the menu. The analyzer will begin a sweep only with the selected trigger
conditions are met. A trigger event is defined as the point at which your trigger source signal meets the
specified trigger level.
Free Run: New sweep starts as soon as possible after the current sweep ends.
RF Trigger: Activates the trigger condition that starts the next sweep if the detected RF envelops
voltage rises to a level set by the RF trigger level.
External: The trigger even is the rising or falling edge of the external trigger signal.
