9. :CHANnel<n>:VERNier
Command Format:
:CHANnel<n>:VERNier {ON|OFF}
:CHANnel<n>:VERNier?
Function Explanation:
The commands are used to set and query the adjustment mode of the vertical
scaling.
When the setting is “OFF”, the scale adjustment manner is “Coarse” and
vertical sensitivity will be adjusted in 1-2-5 regulation.
When the setting is “ON”, the manner is “Fine”. The fine adjustment will
subdivide during the “Coarse” range to improve the vertical resolution.
Returned Format:
Query returns “Coarse” or “Fine”.
Example:
:CHAN2:VERN ON Set the adjustment mode as “Fine”
:CHAN2:VERN? Query returns “Fine”
10. :CHANnel<n>:INPut
Command Format:

Function Explanation:
The commands are used to set and query the input impedance of CH1 or CH2.
<n> is 1 or 2.
Returned Format:
Query returns “50ohm” or “1Mohm”.
Example:
:CHAN2: INP 50OHM Set the input impedance of channel2 as 50Ω
:CHAN2: INP? Query returns “50ohm”
