Averaging
Averaging is used to improve measurement accuracy in low power or noisy
power situations. Increased averaging improves measurement accuracy, but
also reduces measurement speed.
How to set Power Meter Averaging
—Press BW 2 or Meas Setup 4.
— Then choose from the following:
— Averaging Auto Man Off
— Auto Allows the USB Power Sensor to use its Auto Averaging
settings. See the USB Power Sensor documentation for details.
— Man Manually enter an averaging count by setting Num Averages.
— OFF Performs NO averaging.
— Num Averages
Sets the number of Power Meter readings to be
averaged before a valid reading is displayed. When the number is
changed, Averaging is automatically set to Man.
Single or Continuous Measure
This setting determines whether the FieldFox measures continuously or only
once each time the Single
button is pressed. Use Single to conserve battery
power or to allow you to save or analyze a specific measurement.
This setting can be changed at any time without affecting calibration accuracy.
How to set Single or Continuous
—Press Sweep 3.
— Then choose one of the following:
— Single
Automatically sets Continuous OFF and causes FieldFox to
make ONE measurement, then hold for the next Single
key press.
When a data trace is displayed, the entire trace is measured, then
holds. The Hold annotation changes to an arrow --> while the
measurement occurs.
— Continuous OFF ON
Makes continuous measurements. This is the
typical setting when battery power is not critical.
