## Command Syntax

    :WMEMoryN:YRANge <amplitude>

<amplitude> is a double.

Where N identifies one of eight {1:8} possible waveform memories. For example, `:WMEMory4`.

## Query Syntax

    :WMEMoryN:YRANge?

## Description

Sets or queries the waveform memory's vertical range. This is the vertical scale per division value (`:WMEMory:YSCale`) multiplied by eight divisions.

Electrical waveforms are typically volts and optical waveforms are typically watts.

The vertical expansion and contraction is about the center offset value (`:WMEMory:YOFFset`) and not the ground reference.

For optical channels, the offset positions to center the signal on the center graticule with vertical expansion and contraction about the center graticule.

The default value is 100 mV.

## Common Numerical Child Commands

This command supports the use of the following common numerical child commands: `:DEFault`, `:MAXimum`, `:MINimum`, and `:STEP`.
