:CHANnel<n>:UNITs
:CHANnel<n>:UNITs <units>
:CHANnel<n>:UNITs?
Set or query the amplitude display unit of the specified channel.
{VOLTage|WATT|AMPere|UNKNown}
The query returns VOLT, WATT, AMP, or UNKN.
:CHANnel1:UNITs VOLTage /*Set the amplitude display unit of CH1 to V*/
:CHANnel1:UNITs? /*The query returns VOLT*/
:CHANnel<n>:VERNier
:CHANnel<n>:VERNier <bool>
:CHANnel<n>:VERNier?
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.
By default, the fine adjustment is off. At this point, you can only set the vertical scale in
1-2-5 step, namely 10mV, 20mV, 50mV, 100mV…100V (the probe ratio is 10X). 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.
The query returns 1 or 0.
:CHANnel1:VERNier ON /*Enable the fine adjustment function of the vertical scale of
CH1*/
:CHANnel1:VERNier? /*The query returns 1*/
