Resolution; Triggering - Keysight N9912A User Manual

You can also use Run / Hold +/- to toggle between Single and Continuous.

Resolution

Resolution is the number of individual acquisitions that occur in the USB Power
Sensor. This data is read by the FieldFox and plotted across the X-axis to form a
trace. More data points increases measurement resolution. However, more data
points requires more time to acquire, query, and plot.
How to set Resolution
 Press Sweep 3
 Then
 Then choose from the following:

Triggering

For pulse measurements, a trigger signal refers to the event that causes the USB
Peak Power Sensor to initiate measurement acquisition. It does NOT refer to
triggering the FieldFox.
Trigger settings can be used with ALL pulse measurements unless stated otherwise.
A
USB Power Sensor when it is waiting for a pulse signal at the RF Input (Internal) or a
TTL signal at the USB Sensor External Trigger input.
