## Command Syntax

    :MARKer:XN:SOURce:TYPE {WAVeform | SPARameter}

Where N identifies one of four {1:4} markers. For example, `:MARKer2`.

## Description

The source is automatically set to `WAVeform`.

`WAVeform`
  Select waveforms other than S-parameters. channels. Function waveforms can also be selected. This includes an FFT math operator waveform, if the FFT is defined as linear magnitude. Use the `:MARKer:X:SOURce` command to select the actual waveform.
`SPARameter`
  Selects S-parameter waveforms. Use the `:MARKer:X:SOURce:SPARameter` and `:MARKer:X:SOURce:DUT` commands to select the actual waveform. When turned on, a tracking marker that is shown in each Decibels (Hz), Degrees (Hz), and Seconds (Hz) waveform content window that is displayed.
