Learn more about NA Modeformats, including Group Delay, in “Format” on page 46.When enabled, Smo appears on the FieldFox screen.How to set Smoothing— Press BW 2— Then Smoothing ON OFF— Then Sm. Aperture and enter a value between 0 and 25 (percent) using thenumeric keypad.— Press EnterSingle or Continuous MeasureThis setting determines whether the Fiel dFox sweeps continuously or only onceeach time the Single button is pressed. Use Single to conserve battery poweror to allow you to save or analyze a specific measurement trace.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 tomake ONE sweep, then hold for the next Single key press. Hold isannotated in the upper left corner of the display when NOT sweeping,and changes to an arrow --> while the sweep occurs.— Continuous Makes continuous sweeps. This is the typical settingwhen battery power is not critical.— You can also use Run / Hold +/- to toggle between Single and Continuous.Resolution (Number of Data Points)Data points are individual measurements that are made and plotted across theX-axis to form a trace. Select more data points to increase measurementresolution. However, more data points also takes more time to complete anentire measurement sweep.When the Resolution is changed after a calibration is performed, the calbecomes interpolated.
