:CHANnel<n>:VERNier
Syntax :CHANnel<n>:VERNier <bool>
:CHANnel<n>:VERNier?
Description Enable or disable the fine adjustment of the vertical scale of the specified channel, or
query the fine adjustment status of the vertical scale of the specified channel.
Parameter

Default
<n>
Discrete
{1|2|3|4}
--
<bool> Bool {{0|OFF}|{1|ON}} 0|OFF
Explanation By default, the fine adjustment is off. At this point, you can only set the vertical scale in
1-2-5 step, namely 1mV, 2mV, 5mV, 10mV…10V. When the fine adjustment is on, you can
further adjust the vertical scale within a relatively smaller range to improve the vertical
resolution. If the amplitude of the input waveform is a little bit greater than the full scale
under the current scale and the amplitude would be a little bit lower if the next scale is
used, fine adjustment can be used to improve the display amplitude of the waveform to
view the signal details.
Return
Format
The query returns 0 or 1.
Example
:CHANnel1:VERNier ON /*Enable the fine adjustment of the vertical scale of CH1*/
