 | SCALE (Group Delay) Menu This menu is available when TRACE FORMAT is set to Group Delay. Button units are set to: • Button Units: s (seconds), ms (milliseconds), us (microseconds), ns (nanoseconds), ps (picoseconds) • Button Units:% (Percentage) Resolution (Time/Div) Select displays the Resolution (Time/Division) toolbar with available units of s (seconds, ms (milliseconds), us (microseconds), ns (nanoseconds), or ps (picoseconds) per division. Resolution (Time/Div) Field Toolbar  Reference Value (Time) Select displays the Reference Value (Time) toolbar with available units of s (seconds, ms (milliseconds), us (microseconds), ns (nanoseconds), or ps (picoseconds) per division. Reference Value (Time) Field Toolbar  Reference Position (Number) Select allows the user to define a reference position and displays the Reference Position field toolbar. Reference Position (Number) Field Toolbar  Aperture (% of Sweep) The Aperture Percentage is the width of the sweep frequency that is used in the group delay calculation where group delay is the integrated slope of the signal measurement.
