How to set Scale
— Press Scale / Amptd .
— Then choose from the following method
— Autoscale Automatically adjusts the Y-axis to comfortably fit the
Minimum and Maximum amplitude of the trace on the screen.
— Autoscale All Autoscales all of the traces on the screen, useful only for
multi-trace configurations.
—3.Set Scale, acquisition, and Reference Position
—— Scale Manually enter a scale per division to view specific areas
of the trace.
—— Ref Level Manually set the value of the reference line. Enter a
negative value by pressing Run/Hold (+/-) either before or
after typing a value.
—— Ref Pos Manually set the position of the reference line. Values
must be between 0 (TOP line) and 10 (BOTTOM line)
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
— Press Scale / Amptd
— Then More
— Then Magnitude Offset - Offsets the entire data trace by the specified
value.
Scale annotation on the FieldFox screen
