Query returns the setting value of offset in scientific notation. Unit is related to :CHANnel<n>:UNITs.
For example
：
:CHAN1:OFFS 20V
Set the vertical displacement of channel 1 to 20 V.
:CHAN1:OFFS?
Query returns 2.000e001.
:CHANnel<n>:SCALe
Command format
：
:CHANnel<n>:SCALe {<scale> | UP | DOWN}
:CHANnel<n>:SCALe?
Functional description
：
This command is used to set volts/div scale on vertical direction.
<scale>: Volts/div scale value;
UP: Increase one scale based on the current scale of the oscilloscope;
DOWN: Decrease one scale based on the current scale of the oscilloscope.
<n>: {1|2|3|4|5|6|7|8|9}, it represents {CH1|CH2|CH3|CH4|MATH|REFA|REFB|REFC|REFD} separately.
Return format
：
Query returns the current volts/div scale vaule in scientific notation. Unit is related to :CHANnel<n>:UNITs.
For example
：
:CHAN1:SCAL 20V
Set the volts/div scale of channel 1 to 20 V.
:CHAN1:SCAL?
Query returns 2.000e001.
:CHAN1:SCAL UP
Increase one scale based on 20 V volts/div scale.
:CHANnel<n>:UNITs
Command format
：
:CHANnel<n>:UNITs {VOLTs|AMPeres|WATTs|UNKNown}
:CHANnel<n>:UNITs?
Functional description
：
This command is used to set the channel unit to VOLTs, AMPeres, WATTs or UNKNown.
<n>: {1|2|3|4}, it represents {CH1|CH2| CH3|CH4}.
Return format
：
Query returns VOLTs, AMPeres, WATTs or UNKNown.
For example
：
:CHAN1:UNIT VOLT
Set the unit of channel 1 to VOLTs.
:CHAN1:UNIT?
Query returns VOLTs.
:CHANnel<n>:VERNier
Command format
：
:CHANnel<n>:VERNier { {1|ON} | {0|OFF} }
:CHANnel<n>:VERNier?
Functional description
：
This command is used to set scale adjusting mode. If scale adjusting mode sets to ON, which is fine tuning.
Fine tuning can further subdivided within coarse tuning range for improving vertical resolution; if scale
adjusting mode sets to OFF, which is coarse tuning. It can adjust vertical sensitivity by system 1-2-5.
