:FUNCtion Commands
Introduction to
:FUNCtion
Commands
The FUNCtion subsystem controls the math functions in the oscilloscope.
As selected by the OPERation command, these math functions are
available:
• Operators:
• ADD
• SUBTract
• MULTiply
Operators perform their function on two analog channel sources.
• Transforms:
• DIFF — Differentiate
• INTegrate — The INTegrate:IOFFset command lets you specify a DC
offset correction factor.
• FFT — The SPAN, CENTer, VTYPe, and WINDow commands are used
for FFT functions. When FFT is selected, the horizontal cursors
change from time to frequency (Hz), and the vertical cursors change
from volts to decibel (dB).
• SQRT — Square root
Transforms operate on a single analog channel source or on a g(t)
function that is the addition, subtraction, or multiplication of analog
channel sources (specified by the GOFT commands).
With the DSOX3ADVMATH advanced math measurements license, these
additional math functions are available:
• Operators:
• DIVide
• Transforms:
• LINear — Ax + B — The LINear commands set the gain (A) and offset
(B) values for this function.
