(-4 x VerticalScale - VerticalOffset) to
(4 x VerticalScale - VerticalOffset)
--
Explanation  VerticalScale is the vertical scale of the specified analog channel. VerticalOffset is the
vertical position of the specified analog channel.
 By default, the auto threshold function of the analog channels of the oscilloscope is
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:CHANnel1 1.5 /*Set the threshold level of CH1 to 1.5V*/
:DECoder1:THREshold:CHANnel1? /*The query returns 1.500000e+00*/
:DECoder<n>:THREshold:AUTO
Syntax :DECoder<n>:THREshold:AUTO <bool>
:DECoder<n>:THREshold:AUTO?
Description Turn on or off the auto threshold function of the analog channels, or query the status of
the auto threshold function of the analog channels.
Parameter

Default
<n> Discrete {1|2} --
<bool> Bool {{1|ON}|{0|OFF}} 1|ON
Explanation By default, the auto threshold function of the analog channels of the oscilloscope is
turned on. To set the threshold level manually, send this command to turn off the auto
threshold function and use the commands in Related Commands to set the threshold
manually.
Return
Format
The query returns 1 or 0.
Example
