Defining a Function
+ (add) The voltages of the two selected operands are added together
in a point-by-point manner.
— (subtract) The voltage of the second operand is subtracted from the
first operand in a point-by-point manner.
x (multiply) The voltages of the two selected operands are multiplied
together in a point-by-point manner.
Vs (versus) The voltage of the first operand is used to determine the
displayed point’s vertical position, and the voltage of the second operand
is used to determine the displayed point’s horizontal position.
Because the versus functions does not create a single valued waveform, you
cannot store a versus function in a waveform memory or make measurements
on the resultant waveform. However, you can store it in a pixel memory, and
you can place markers on the versus function. The voltage range of the first
operand is used to determine the horizontal range.
Magnify The voltage of the operand is scaled and positioned in a
point-by-point manner.
Inv (inverse) The voltage of the operand is inverted in a point-by-point
manner.
Int (integrate) The voltage of the operand is intergrated in a
point-by-point manner. Ifa data point is not encountered in the operand,
integration uses the next valid data point. Only the available data is
integrated. Default scaling is determined by the original operand.
