How to set Single or Continuous
— Press
Sweep 3

—
Single Automatically sets Continuous OFF and causes the FieldFox
to query the USB Power Sensor ONCE, then hold for the next Single
key press. Hold is annotated in the upper left corner of the display.
—
Continuous
Queries the USB Power Sensor whenever a valid trigger
signal is present. This is the typical setting when battery power is not
critical.
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

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
Waiting for Trigger
message on the FieldFox screen is posted on behalf of
the 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.
