Function definition
For each trace, definition of a mathematical function and the vertical scale.
If "Advanced" mode is not activated, simple functions (Inversion, Addition,
Subtraction, Multiplication and Division of curves) can be selected and
linked to the curves 1 or 2.
In "Advanced" mode, mathematical functions can be defined literally.
The mathematical function can be defined on 2 lines.
•
The mathematical function can be defined on 2 lines.
•
mathx cannot be used in the definition of a function.
The key deletes the character preceding the cursor in the window.
Functions
8 predefined mathematical functions can be linked to the traces:
( ∗) t = abscissa of the sample in the acquisition memory.
divh(1) is equivalent to 250 samples (counts) = 1 horizontal division
(or 5000 samples if the EXTENDED ACQUISITION MEMORY
option is installed).
Validation of the selections by "
OK
". Exit from the menu without modification by
"
Cancel
".
If … then …
... the dynamic calculation of the
vertical scale is impossible
... a message indicates that the
measuring unit on this function will
be vertical division (div).
... the dynamic calculation of the vertical
scale is possible
... it takes into account of the
sensitivities of the channel sources.
Particular cases
: Value of the measuring unit
CHx + CHy Sensitivity and measuring unit used on CHx
CHx - CHy Sensitivity and measuring unit used on CHx
In each cases, the measuring unit can be re-defined and a coefficient can be
applied to the measurement results (refer to §. Vertical scale).
