Argument Type The +, -, x, / operations require a second argument. The Argument Type
function selects between a constant argument and another trace. A con-
stant argument adds or subtracts a constant to the trace or multiplies or
divides the trace by a constant. A trace argument uses a data trace as
the argument. In this case, calculations are performed on a point by point
basis. The trace which is in the active chart display is where the results
are stored. The active chart determines the time window over which
these operations are performed. In the case of divide, the trace in the
active display is divided by the argument trace.
In all cases, the arguments are not corrected for units. Constants should
be entered in the trace units. Adding two traces adds their values, even if
their units are not the same. The units of the resulting trace are not
changed. A trace may be scaled before being used as an argument
using x or / with a constant conversion factor.
If the Argument type is a constant, then the Argument and Cursor func-
tions are displayed.
Constant Value Pressing the Constant Value key activates the constant
argument entry field. Use the keypad to enter a numerical
argument. Integer (-3), real (-3.0), or floating point (-
0.3E+1) formats are all allowed.
Cursor Value to Arg. The Cursor Value to Arg key will copy the trace value of
the cursor marker to the constant argument field above.
This is convenient when subtracting a baseline or normal-
izing to a data point.
If the Argument type is a trace, then the trace selection function is
displayed.
Trace Pressing the Trace key activates the trace number entry
field. Use the knob to select trace 1, 2, 3 or 4. A trace must
be stored in order to be used as an argument.
Return The Return key will return to the main Math menu.
