Please see the FieldFoxSpecifications for expected power levels— Low Sets output power to approximately –42 dBm.— Man Set output power to an arbitrary value.— Thenpress Nominal Power— Then enter a value using the numeric keypad, the arrows, or therotary knob.— Press Enter.AveragingAveraging helps to reduce the effects of random noise on a measurement. TheFieldFox computes the displayed value over several consecutive readings.Average count determines the number of readings to average. The higher theaverage count, the greater the amount of noise reduction.An average counter is shown in the left edge of the screen as Avg N. Thisshows the number of previous readings that have been averaged together.When the counter reaches the specified count, then a ‘running average’ of thelast N readings is displayed.Average count = 1 means there is NO averaging.This setting can be changed at any time without affecting calibration accuracy.How to set Averaging— Press Meas Setup 4— Then More— Then Avg N where N is the current count setting.— Enter a value using the numeric keypad. Enter 1 for NO averaging.— Press Enter.To restart the averaging process, press Meas Setup 4, then More, then RestartSingle or Continuous MeasureThis setting determines whether the FieldFox measures continuously or onlyonce each time the Single button is pressed. Use Single to conserve batterypower or to allow you to save or analyze a specific measurement.
