:CHANnel<n>:VERNier
Syntax
:CHANnel<n>:VERNier <bool>
:CHANnel<n>:VERNier?
Description
Enables or disables the fine adjustment of the vertical scale of the specified analog channel; or queries the
on/off status of the fine adjustment function of the vertical scale of the specified analog channel.
Parameter
Name Type Range Default
<n> Discrete {1|2|3|4} --
<bool> Bool {{1|ON}|{0|OFF}} 0|OFF
Remarks
 1|ON: enables the fine adjustment function. Rotate VERTICAL
SCALE to further adjust the
vertical scale at a relatively smaller step.
0|OFF: disables the fine adjustment function. Rotate VERTICAL
SCALE to adjust the vertical scale
within the adjustable range at 1-2-5 step.
 To better observe the signal details, enable the fine adjustment function to improve the waveform
display amplitude if the following conditions occur: the amplitude of the input waveform is a little bit
greater than the full scale of the current scale; using the next scale for adjustment makes the
amplitude a little bit lower than expected.
Return Format
The query returns 1 or 0.
