UTD2000E Series Osilloscope Programming Manual

    

 

 
LED light staus

：

0 presents light off, 1 presents light on. 

 

For example： 

:KEY:AUTO

   

 

 

 

 

set oscilloscope control parameter automatically 

:KEY:AUTO:LOCK ON/OFF   

 

lock/unlock button   

:KEY:AUTO:LOCK? 

 

 

 

query return this key lock status, 1 presents locked 

:KEY:AUTO:LED? 

 

 

query return LED status

，

0 presents light off   

 

CHANnel Command 

This command is to set channel independently. <n> take value as 1/2/3/4/5/6/7/8/9, it 
presents {CH1/CH2/ CH3/ CH4/ MATH/ REF-A/ REF-B/ REF-C/ REF-D}. 

 
Notes: this command in instruction set is not only valid for physical channel, but also 
valid for MATH and reference channel parameter. 

:CHANnel<n>:BWLimit 

 

Command format： 

:CHANnel<n>:BWLimit {{1|ON}|{0|OFF}} 
:CHANnel<n>:BWLimit? 

 

Functional description： 

Set bandwidth limit function is ON (turn on bandwidth to 20MHz

，

to reduce display noise) or   

OFF (turn off bandwidth to full display

）

 

 

Return format： 

Query return 1 or 0

，

it presents ON or OFF. 

 

For example： 

:CHAN1:BWL ON   

 

turn on channel 1 bandwidth limit 

:CHAN1:BWL?     

 

query return 1

，

it presents channel 1 bandwidth limit is turn on 

:CHANnel<n>:COUPling 

 

Command format： 

:CHANnel<n>:COUPling {DC|AC|GND} 
:CHANnel<n>:COUPling? 

 

Functional description： 

Set channel coupling mode, DC presents AC and DC component of input signal; AC presents DC 
component of blocking input signal; GND (grounding) presents break input signal.   

 

Return format： 

Query AC, DC or GND. 

 

For example： 

 

:CHAN1:COUP DC   

 

 

 

 

set channel 1 coupling mode as DC 

:CHAN1:COUP?     

 

 

 

 

query return    DC
