 | Single Limit Limit Line (On Off) This key toggles the limit line On or Off. Limit line amplitude is stored even when turned off. The type of limit line, upper or lower, is determined by the measurement. For example, VSWR and Return loss utilize an upper limit, and Cable Loss utilizes a lower limit. The limit line changes from green to red when the limit is reached. Any points on a trace that touch or exceed a limit line setting are also displayed in Red. Edit Value Press this key to change the amplitude of the limit line with the Up/Down Arrow keys, rotary knob, or the number keypad. Limit Alarm (On Off) When turned On, the Limit Alarm sounds a repeating beep when the trace touches the limit line. Pass/Fail Msg (On Off) When turned On, a Pass or Fail message is displayed to indicate whether the trace touches or exceeds the limit line (Fail). See Figure: Pass / Fail Messages. Limit Preset Turns the limit line Off and clears amplitude information. The next time that a limit line is turned On, it is displayed at the default location (center of the display). |
