TIMebase Command 

This  command  is  to  change  the  current  channel  horizontal  scale  (time  base)  and 
horizontal position of trigger in memory (trigger offset). Horizontal scale change will 
make waveform expand or shrink relative to screen center. Horizontal position change 
will make wave shift relative to screen center. 

:TIMebase:MODE 

 

Command format: 

:TIMebase:MODE {MAIN | WINDow} 
:TIMebase:MODE?

 

 

Functional description: 

Set timebase mode, MAIN or WINDow (zoom timebase <Zoomed>

 

 

Return format: 

Query return MAIN or WINDow. 

 

For example: 

:TIM:MODE MAIN   

 

 

 

 

set timebase mode as MAIN 

:TIM:MODE?    

 

 

 

 

 

query return MAIN 

:TIMebase:OFFSet 

 

Command format: 

:TIMebase:OFFSet <offset> 
:TIMebase:OFFSet?

 

 

Functional description: 

For adjust MAIN offset value,

 

wave shift relative to screen center. 

 

Return format: 

Query return<offset> value by scientific notation

unit is s. 

 

For example: 

:TIM:OFFS 1s   

 

 

 

 

 

set MAIN offset value as 1s 

:TIM:OFFS?     

 

 

 

 

 

query return 1.000e000
