## Command Syntax

    :CHANnelN:YSCale  <scale>

<scale> is a double.

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is `CHANnel4_2`.

## Query Syntax

    :CHANnelN:YSCale?

## Description

Sets the selected channel's vertical sensitivity and sets the volts-per-division scale (watts-per-division for optical channels). The vertical expansion and contraction is about the center offset value (`:CHANnel:YOFFset`) of the display 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.
