Read-out Functions

The read-out functions are built-in functions for reading various values related to a

analysis tool which is marker, cursor, or line. You can use these functions to perform

complex analysis of the measurement results.

To read the value of the read-out function, use a numeric variable. 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 analysis tool that is referred to by the read-out function is not displayed, the

read-out function uses the position at which it was most recently displayed. If the

analysis tool has not been displayed, the read-out function returns invalid data.

In the application test definition, to use a read-out function in a component such as

ASSIGN, IF, FOR, Application Test, and Classic Test, place the Auto Analysis

component before the component, and set the analysis tool associated with the

read-out function.

Functions for Marker

@MI Returns the index number of measurement data at the marker location.

If interpolation mode is enabled and the marker is located 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 returns the value for the selected axis.

@MYn Returns the value of the Yn coordinate at the marker location (n: 1 to 8, integer).
