Signal Generator OverviewFront Panel Overview – N5181A/82A MXG17. Q Input (vector models only)Connector Type: female BNC Impedance: 50 ΩSignalAn externally supplied analog, quadrature–phase component of I/Q modulation.The signal level is = 0.5 V rms for a calibrated output level.Damage Levels1 V rmsSee also, “I/Q Modulation” on page 198.18. KnobRotating the knob increases or decreases a numeric value, or moves the highlight to the next digit,character, or item in a list. See also, “Front Panel Knob Resolution” on page 28.19. Incr SetThis hardkey enables you to set the increment value of the currently active function. The incrementvalue also affects how much each turn of the knob changes an active function’s value, according tothe knob’s current ratio setting (see “Front Panel Knob Resolution” on page 28).20. ReturnThis hardkey enables you to retrace key presses. In a menu with more than one level, the Return keyreturns to the prior menu page.21. More and LEDWhen a menu contains more softkey labels than can be displayed, the More LED lights and a Moremessage displays below the labels. To display the next group of labels, press the More hardkey.22. Power Switch and LEDsThis switch selects the standby mode or the power on mode. In the standby position, the yellow LEDlights and all signal generator functions deactivate. The signal generator remains connected to theline power, and some power is consumed by some internal circuits. In the on position, the green LEDlights and the signal generator functions activate.8 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
