Magnitude Offset
Magnitude Offset allows you to offset the magnitude (not phase) data by a
fixed and/ or sloped value in dB. If the display format is Linear Magnitude or
Real (unitless), the conversion from dB is performed and the correct amount of
offset is implemented.
The Magnitude offset setting affects only the active trace.
How to set Magnitude Offset

Magnitude Offset
- Offsets the entire data trace by the specified
value.
—Then enter a positive or negative offset value in dB using the numeric
keypad, the arrows, or the rotary knob. Press a multiplier key.

.
— And/or press
Slope
- Offsets the data trace by a value that changes linearly
with frequency. The offset slope begins at 0 Hz. and continues to the stop
frequency. The offset value at the start frequency is then calculated from 0
Hz.
—Then enter a positive or negative offset slope value in dB/GHz using
the numeric keypad, the arrows, or the rotary knob. Press a
multiplier key. Learn about multiplier abbreviations in

Abbreviations” on page 34

Electrical Delay
Electrical delay is a mathematical function that simulates a variable length of
lossless transmission line. Use the electrical delay feature to compensate for
the linear phase shift through a device and view only the deviation from linear
phase of the device.
You can set the electrical delay independently for each measurement trace. To
apply an electrical delay to all measurement traces, use Port Extensions. Learn
how in
“Port Extensions” on page 54
