- :MEASure:MARKer:Y:STATus?
- :MEASure:MARKer:Y:STATus:REASon?

## Query Syntax

    :MEASure:MARKer:Y{1:4}{A:C}?

This command supports the `STATus?` and `STATus:REASon?` common child commands.

## Description

This command queries the amplitude of a Y-axis manual-line marker or tracking marker pair.

With S-parameter magnitude, phase, and group delay waveforms displayed, you can create one tracking marker at an X value that has three different Y values, one from each waveform at the same X value. In other words, this single tracking marker has three Y values at the same X position. All three Y values are shown in additional Magnitude columns in the marker results table. The following table shows how to identify the Y values in the query. Each waveform is identified using a letter from A to C.

Example of Querying S-Parameter Y Marker Values
Y Value | Example Marker 2 Query
--- | ---
Magnitude Y Value | :MEASure:MARKer:Y2A?
Phase Y Value | :MEASure:MARKer:Y2B?
Group Delay Y Value | :MEASure:MARKer:Y2C?

To turn on a marker, use the commands in the :MARKer subsystem.
