Read Out Functions
Read Out Functions
The read out functions are built-in functions for reading various values related to the
marker, cursor, or line. You can use these functions to perform complex analysis of
the measurement results. They are available only for the Analysis Functions.
To read the value of the read out function, use a numeric variab
le. The following
example reads the X intercept of the line 1 and enters it to the variable A.
Example
A=@L1X
NOTE In this section, n of the function name is an integer (1 to 8), and m is 1 or 2.
You cannot assign a data variable that includes a read out function to an axis of a
graphics plot.
If the marker, cursor, or line that are referred to by the read out f
unction are not
displayed, the read out function uses the position at which it was most recently
displayed. If the marker, cursor, and line have not been displayed, the read out
function returns invalid data.
Functions for Marker
@MI Returns the index number of measurement data at the marker location.
If interpolation mode is enabled and the marker is lo
cated between the measurement
data, this function returns a non-integer value.
@MX Returns the value of the X coordinate at the marker location.
@MY Returns the value of the Y coordinate at the marker location.
If there are two Y axes, this function retu
rns the value for the s
elected axis.
@MYn Returns the value of the Yn coordinate
at the marker location (n: 1 to 8, integer).
Functions for Cursor
@CX Returns the value of the X coordinate at the active cursor position.
@CY Returns the value of the Y coordinate at the active cursor position. If there are two Y
axes, this
function returns the value for the selected axis.
