RIGOL  Programming Introduction 
 
Programming Guide for DS1000CA Series 
Command Format:   
:MEASure:PWIDth? [<source>]   
 
Function Explanation: 
This command is used to query the positive pulse width of the waveform. The 
options of <source> are CHANnel1 or CHANnel2. 
 
Returned Format: 
Such as 5.00e-04, the unit is s. 
 
 
17. :MEASure:NWIDth?  
Command Format:   
:MEASure:NWIDth? [<source>]   
 
Function Explanation: 
This command is used to query the negative pulse width of the waveform. The 
options of <source> are CHANnel1 or CHANnel2. 
 
Returned Format: 
Such as 5.00e-04, the unit is s. 
 
 
18. :MEASure:PDUTycycle?  
Command Format:   
:MEASure:PDUTycycle? [<source>]  
 
Function Explanation: 
This command is used to query the positive duty cycle of the waveform. 
Generally,  duty  cycle  is  in  terms  of  percentage,  and  the  transformational 
relation of the overshoot value and percentage is: PDUT*100.    For example: 
PDUT = 5.00e-1 mens this duty cycle is 50%. 
 
Returned Format: 
Such as 5.00e-01.
