Measure Commands

DELTatime

Command :MEASure:DELTatime [<source>[,<source>]]

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 18-4 on page 18-39 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 18-4 on page 18-39

for a list of the result states.

Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”

20 OUTPUT 707;”:MEASURE:DUTYCYCLE?”
