RIGOL
:CHANnel<n>:PROBe:BIAS
Syntax
:CHANnel<n>:PROBe:BIAS <bias>
:CHANnel<n>:PROBe:BIAS?
Description Sets or queries the probe bias voltage of the specified channel.
Parameter Name
<n>
<bias>
Remarks This function is used to adjust the signal under test that exceeds the input dynamic

range of the probe amplifier to an appropriate range to ensure the signal integrity.
This command is only valid when an active probe is correctly connected.

Return The query returns the probe bias voltage in scientific notation.
Format
:CHANnel<n>:UNITs
Syntax :CHANnel<n>:UNITs <units>
:CHANnel<n>:UNITs?
Description Sets or queries the amplitude display unit of the specified analog channel.
Parameter
Name
<n>
<units>
Return The query returns VOLT, WATT, AMP, or UNKN.
Format
Example :CHANnel1:UNITs VOLTage
:CHANnel1:UNITs?
: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
<n>
<bool>
Remarks By default, the fine adjustment is Off. At this time, you can set the vertical scale at 1-2-5
step, i.g. 10 mV, 20 mV, 50 mV, 100 mV......100 V. When the fine adjustment is enabled,
you can further adjust the vertical scale within a relatively smaller range to improve
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 amplitude of waveform display
to view signal details.
