:MEASure:RJDJ:TJRJDJ?
Query
:MEASure:RJDJ:TJRJDJ?
The :MEASure:RJDJ:TJRJDJ? query returns the Total Jitter (TJ), Random
Jitter (RJ), and the Deterministic Jitter (DJ) measurements. These values
are returned as comma separated values using the following format:
Returned Format
[:MEASure:RJDJ:TJRJDJ] TJ(<tj_format>),<tj_result>,<tj_state>,
RJ(<rj_format>),<rj_result>,rj_state,
DJ(<dj_format>),<dj_result>,<dj_state><NL>
<tj_format>
<rj_format>
<dj_format>
The format value tells you something about how the measurement is made.
For instance, TJ(1E- 12) means that the TJ measurement was derived using
a bit error rate of 1E- 12. A format of (rms) means the measurement is a
root- mean- square measurement. A format of (d- d) means the
measurement uses from a dual- Dirac delta model used to derive the
measurement. A format of (p- p) means the measurement is a peak- to- peak
measurement.
<tj_result>
<rj_result>
<dj_result>
The measured results for the RJDJ measurements. A value of 9.37
means that the oscilloscope was unable to make the measurement.
<tj_state>
<rj_state>
<dj_state>
The measurement result state. See Table 24 for a list of values and
descriptions of the result state value.
Example This example places the Total Jitter (TJ), Random Jitter (RJ), and the
Deterministic Jitter (DJ) measurements in the strResults variable and
displays it on the computer's screen.
Dim strResult As String ' Dimension variable.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:RJDJ:TJRJDJ?"
strResult = myScope.ReadString
Debug.Print strResult
