## Query Syntax

    :CGMemoryN:YSCale?

Where N identifies one of eight {1:8} color grade memories. For example, the color grade memory 2 would be identified as `:CGMemory2`.

## Description

Queries the vertical scale (sensitivity) stored for the waveform in eye-memory. This is volts-per-division for electrical waveforms and watts-per-division for optical waveforms. It may or may not be the same as Infiniium's current setting. The vertical expansion and contraction is about the center offset value (`:CGMemory:YOFFset?`) stored in color grade memory and not at the ground reference. For optical channels, vertical expansion and contraction is about the second graticule division from the bottom of the display screen and also not at the ground reference.
