## Command Syntax

    :ANNotations:ANNotation{N}:SOURce <source_waveform>

Where N identifies one of 16 possible annotations {1:16}. For example, `ANNotation7`.

Where <source_waveform> can be one of the following:

- `CHANnel<connection1-8>_<ch1-8>`; With connection 1, the "`1_`" part is optional, and you can simply use `CHANnel<ch1-8>`.
- `DIFF{1:4}`
- `COMM{1:4}`
- `CGMemory{1:8}`
- `FUNCtion{1:64}`
- `WMEMory{1:8}`

## Query Syntax

    :ANNotations:ANNotation{N}:SOURce?

## Description

This command associates an annotation with a source waveform and its window and grid.

For all annotation types except `STATionary`, the annotation's X and Y values are appropriate for the source waveform. For example, for an FFT math function waveform source, the annotation's X values are frequency values and the annotation's Y values could be dBm values. (For `STATionary` annotations, X and Y values are percentages of the source waveform grid's width and height.)
