This feature is selected on the Average dialog.
When selected, each data point is measured the specified number of averages before stepping to the next data point. When point trigger is selected, only one trigger is required for each data point regardless of the number of averages.
This feature is selected on the Sweep Setup dialog.
In Point Sweep mode, the VNA measures both the forward and reverse parameters at each frequency point before stepping to the next frequency. The display trace is updated as each data point is measured. Point sweep is the same as stepped sweep mode of the 8510 and 8530.
This feature is selected under Trigger Mode on the Trigger dialog.
Available ONLY when Point Sweep is selected. Each trigger signal causes two identical measurements to be triggered separately - one trigger signal is required for each measurement. Other trigger mode settings cause two identical parameters to be measured simultaneously.
Trace triggering is NOT permitted when a channel is using a 2 port (or more) S-Parameter calibration.
