Remote command:
CALC:MATH:MODE LIN, see CALCulate<n>:MATH:MODE on page 848
Log ← Trace Math Mode
Activates logarithmic subtraction.
This subtraction method only takes effect if the grid is set to a logarithmic scale (see
Range softkey), i.e. the unit of the data is dBm. In this case the values are subtracted
in dBm. Otherwise (i.e. with linear scaling) the behavior is the same as with linear sub-
traction (see Lin softkey). For further information on logarithmic scaling refer to the
Average Mode softkey.
Remote command:
CALC:MATH:MODE LOG, see CALCulate<n>:MATH:MODE on page 848
Power ← Trace Math Mode
Activates linear power subtraction.
The power level values are converted into unit Watt prior to subtraction. After the sub-
traction, the data is converted back into its original unit.
Unlike the linear mode, the subtraction is always done in W.
Remote command:
CALC:MATH:MODE POW, see CALCulate<n>:MATH:MODE on page 848
Trace Math Position
Opens an edit dialog box to define the zero point in % of the diagram height. The range
of values extends from -100 % to +200 %.
Remote command:
CALCulate<n>:MATH:POSition on page 848
Trace Math Off
Deactivates any previously selected trace math functions.
Remote command:
CALC:MATH:STAT OFF, see CALCulate<n>:MATH:STATe on page 848
6.3.1.2 Configuring Traces
1. To open the trace wizard, press the TRACE key and then the "Trace Wizard" soft-
key (see "Trace Wizard" on page 199).
Tip: Context-sensitive menus for traces. Traces have context-sensitive menus. If
you right-click on a trace in the display or a trace setting in the information channel
bar (or touch it for about 1 second), a menu is displayed which corresponds to the
softkey functions available for traces. This is useful, for example, when the softkey
display is hidden.
If a menu entry contains an arrow to the right of it, a submenu is available for that
entry.
To close the menu, press the ESC key or click in the display outside of the menu.
