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: 
:CHANnel<n>:INPut {50OHM|1MOHM} 
:CHANnel<n>:INPut? 
 
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” 
 
Note: This command is effective only for DS1202CA and DS1302CA .
