Keysight N9923-90001 User’s Guide49NA (Network Analyzer) ModeNA Mode SettingsMagnitude OffsetMagnitude Offset allows you to offset the magnitude (not phase) data by afixed and/ or sloped value in dB. If the display format is Linear Magnitude orReal (unitless), the conversion from dB is performed and the correct amount ofoffset is implemented.The Magnitude offset setting affects only the active trace.How to set Magnitude Offset— Press Scale / Amptd— Then More— Then Magnitude Offset - Offsets the entire data trace by the specifiedvalue.—Then enter a positive or negative offset value in dB using the numerickeypad, the arrows, or the rotary knob. Press a multiplier key.Learn about multiplier abbreviations in “Multiplier Abbreviations” onpage 34.— And/orpress Slope - Offsets the data trace by a value that changes linearlywith frequency. The offset slope begins at 0 Hz. and continues to the stopfrequency. The offset value at the start frequency is then calculated from 0Hz.—Then enter a positive or negative offset slope value in dB/GHz usingthe numeric keypad, the arrows, or the rotary knob. Press amultiplier key. Learn about multiplier abbreviations in “MultiplierAbbreviations” on page 34.Electrical DelayElectrical delay is a mathematical function that simulates a variable length oflossless transmission line. Use the electrical delay feature to compensate forthe linear phase shift through a device and view only the deviation from linearphase of the device.You can set the electrical delay independently for each measurement trace. Toapply an electrical delay to all measur ement traces, use Port Extensions. Learnhow in “Port Extensions” on page 54.Learn how to set Phase formats in “Phase Offset” on page 50.How to set Electrical Delay— Press Scale / Amptd— Then More— Then Electrical Delay
