24 Measure Commands
:MEASure:DELTatime
Command :MEASure:DELTatime [<source>[,<source>]]
The :MEASure:DELTatime command measures the delta time between two
edges. If one source is specified, the delta time from the leading edge of
the specified source to the trailing edge of the specified source is
measured. If two sources are specified, the delta time from the leading
edge on the first source to the trailing edge on the second source is
measured.
Sources are specified with the :MEASure:SOURce command or with the
optional parameter following the :MEASure:DELTatime command. The rest
of the parameters for this command are specified with the
:MEASure:DEFine command.
The necessary waveform edges must be present on the display. The query
will return 9.99999E+37 if the necessary edges are not displayed.
<source> {CHANnel<N> | FUNCtion<N> | WMEMory<N> | CLOCk | MSPectrum |
EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N> CHANnel<N> is an integer, 1 - 4.
FUNCtion<N> and WMEMory<N> are:
An integer, 1 - 4, representing the selected function or waveform memory.
Example This example measures the delta time between channel 1 and channel 2.
myScope.WriteString ":MEASURE:DELTATIME CHANNEL1,CHANNEL2"
Query :MEASure:DELTatime? [<source>[,<source>]]
The :MEASure:DELTatime? query returns the measured delta time value.
Returned Format
[:MEASure:DELTatime] <value>[,<result_state>]<NL>
<value> Delta time from the first specified edge on one source to the next
specified edge on another source.
