Explanation  VerticalScale is the vertical scale of the specified analog channel. VerticalOffset is the
vertical position of the specified analog channel.

turned on. To set the threshold level manually, send
the
:DECoder<n>:THREshold:AUTO command to turn off the auto threshold
function.
Return
Format
The query returns the level in scientific notation.
Example
:DECoder1:THREshold:CHANnel4 1.5 /*Set the threshold level of CH4 to 1.5V*/
:DECoder1:THREshold:CHANnel4? /*The query returns 1.500000e+00*/
