TRACE MATH
T1-T2+REF
-> T1
T1-T3+REF
-> T1
T1-T4+REF
-> T1
T1-REF
->T1
The T1-T2+REF, T1-T3+REF, T1-T3+REF and T1-REF softkeys subtract the
traces and add the set level to the difference. If the reference line is switched
on (see key D LINES), the level value of the reference line instead of the
reference level is added to the difference. Thus, the differential curve can be
positioned anywhere on the screen by shifting the reference line. The
difference of the two traces with respect to the reference line is displayed.
The T1-REF softkey subtracts the level of the reference line from the trace
level.
To indicate that the trace is a difference trace, a enhancement label is
displayed at the right margin of the measurement value diagram (1-2, 1-3, 1-
4, 1-R). In TRACE 1 main menu, the TRACE MATH softkey is on a coloured
background to show that the function is being used.
Important: For a display with two measurement windows, not all
combinations are allowed if the sweep data for screen A and
screen B are not the same. Only the traces allowed in the screen
can be combined (in screen A, only trace 1 with trace 3; in
screen B, only trace 2 with trace 4).

TRACE MATH
OFF
The TRACE MATH OFF softkey switches the math function off. The softkey
is only available when a conversion function is enabled.
IEC/IEEE-bus command :CALCulate:MATH:STATe OFF
ADJUST TO
TRACE
The ADJUST TO TRACE softkey restores the original instrument settings
when the corresponding trace is set to VIEW and the current instrument
settings are different than those of the trace data.
If a trace is frozen with VIEW, changes in the instrument settings can be
made without influencing the trace. An asterisk( * ) at the edge of the display
screen indicates that the current instrument settings are different than those
in effect when the trace was recorded. In this case, the ADJUST TO TRACE
softkey is presented with which the original instrument setting can be
restored.
