## Query Syntax

    :MEASure:LLINeN:LINEM:FPOints?

Where N identifies one of 64 {1:64} possible limit line tests. For example, `:LLINe23`.

Where M identifies one of 16 {1:16} possible limit lines.

## Description

Queries the number of failed data points for a specific limit line defined within a Limit Line Test. To query the sum of all failed data points in all defined limit lines in a Limit Line Test, use the `:MEASure:LLINe:FPOints?` query. To load and display a Limit Line Test, use the `:LLINe:DISPlay` command.

In the following picture, the `:MEASure:LLINe1:LINE1:FPOints?` query would return the value 3. The `:MEASure:LLINe1:LINE2:FPOints?` query would return the value 6.

To return the pass/fail margin for a limit line, use the `:MEASure:LLINe:LINE:MARGin?` query. To return the time value for the data point where the pass/fail margin occurs, use the `:MEASure:LLINe:LINE:MLOCation?` query.

Only displayed data points are analyzed. For example, if you zoom in on the waveform so that a portion of a limit line is off screen, any failed data point that exists off screen will not be counted.
