:MEASure:NDUTy

Command Syntax
:MEASure:NDUTy [<source>]
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion<m> | MATH<m>
<digital channels> ::= DIGital<d> for the MSO models
<d> ::= 0 to (# digital channels - 1) in NR1 format
<n> ::= 1 to (# of analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
The :MEASure:NDUTy command installs a screen measurement and starts a
negative duty cycle measurement on the current :MEASure:SOURce. If the
optional source parameter is specified, the current source is modified.
The signal must be displayed to make the measurement. This command is not available if the
NOTE
source is FFT (Fast Fourier Transform).
Query Syntax
:MEASure:NDUTy? [<source>]
The :MEASure:NDUTy? query measures and outputs the negative duty cycle of the
signal specified by the :MEASure:SOURce command. The value returned for the
duty cycle is the ratio of the negative pulse width to the period. The negative pulse
width and the period of the specified signal are measured, then the duty cycle is
calculated with the following formula:
Return Format
<value><NL>
<value> ::= ratio of negative pulse width to period in NR3 format
