Measure Commands
DUTYcycle
Measures the time delay between two edges. If no source is specified, then the sources spec-
ified using the :MEASure:SOURce command are used. If only one source is specified, then the
edges used for computing delta time belong to that source. If two sources are specified, then
the first edge used in computing to delta time belongs to the first source and the second edge
belongs to the second source.
Mode Oscilloscope and TDR modes
<source> {CHANnel<N>| FUNCtion<N> | WMEMory<N> | RESPonse <N>}
<N> An integer, from 1 through 4.
Query :MEASure:DELTatime? [<source>[,<source>]]
The query returns the measured delta time value.
Returned Format [:MEASure:DELTatime] <value> [,<result_state>]<NL>
<value> is the delta time from the first specified edge on one source to the next specified
edge on another source. If SENDVALID is ON, the <result_state> is returned with the mea-
surement result. Refer to Table 18-3 on page 18-30 for a list of the result states.
Examples 10 OUTPUT 707;”:MEASURE:DELTATIME CHANNEL1,CHANNEL2”
10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:DELTATIME?”
NOTE When receiving numeric data into numeric variables, turn off the headers. Otherwise, the headers may cause
misinterpretation of returned data.
DUTYcycle
Command :MEASure:DUTYcycle [<source>]
Measures the ratio of the positive pulse width to the period. Sources are specified with the
MEASure:SOURce command or with the optional parameter following the DUTYcycle com-
mand. <source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N>}. <N> for channels is
dependent on the type of plug-in and its location in the instrument. For functions: 1 or 2. For
waveform memories (WMEMORY): 1, 2, 3, or 4.
Mode Oscilloscope mode only.
Query :MEASure:DUTYcycle? [<source>]
The query returns the measured duty cycle of the specified source.
Returned Format [:MEASure:DUTYcycle] <value>[,<result_state>]<NL>
<value> is the ratio of the positive pulse width to the period. If SENDvalid is ON, the
<result_state> is returned with the measurement result. Refer to Table 18-3 on page 18-30
for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:DUTYCYCLE?”
FALLtime
Command :MEASure:FALLtime [<source>]
