The units of the constants are adjusted to the format of the active trace. Setting all values to zero (Clear
All Values) restores the original trace.
Effect of the constants
The trace points are modified according to the formula displayed in the lower part of the dialog:
The formula and the different constants are adjusted to the different display formats of a trace:
 The Magnitude factor shifts a dB Mag trace in vertical direction, leaving the phase of a complex
parameter unchanged.
 The Phase factor rotates a trace that is displayed in a polar diagram around the origin, leaving the
magnitude unchanged.
 The Real added constant shifts a real trace in vertical direction, leaving the imaginary part
unchanged.
 The Imaginary added constant shifts a imaginary trace in vertical direction, leaving the real part
unchanged.
Shifting the trace by means of constant values is a simple case of trace mathematics. Use the Define
Math dialog to define more complicated mathematical operations.

Max Hold On, Min Hold On
Enables (if selected) or disables the max hold (peak hold) or min hold function for the active trace. With
enabled max hold or min hold function, the displayed trace shows the maximum or minimum values that
the analyzer acquired since the start of the measurement. The max hold and min hold trace is real, it is
based on the magnitude of the trace values (the phase values are discarded).
The max hold or min hold process can be restarted any time using Restart Hold. It is also restarted
automatically when the channel or trace settings are changed so that the previous measurement results
are no longer compatible.
Depending on the selected export file format and trace format, a data export (Export Complex Data,
Export Formatted Data) may require complex trace data. In such situations, the analyzer exports the last
