Channel<N>:Units; Channel<N>:Vernier - Rigol DS1000Z Series Programming Manual

RIGOL
:CHANnel<n>:UNITs
Syntax
:CHANnel<n>:UNITs <units>
:CHANnel<n>:UNITs?
Description
Set or query the amplitude display unit of the specified channel.
Parameter
Name
<n>
<units>
Return
The query returns VOLT, WATT, AMP or UNKN.
Format
Example :CHANnel1:UNITs VOLTage
: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
Name
<n>
<bool>
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
The query returns 0 or 1.
