Pulse Measurement Settings
How to set Single or Continuous
— Press Sweep 3
— Then choose one of the following:
— 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 OFF ON 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
— Press Sweep 3
— Then Resolution
— Then choose from the following:
— Low 240 data points.
— Medium 1000 data points.
— High Calculated value - approximately 8000 data points.
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.
