Measure Commands
HISTogram:STDDev?
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:HISTOGRAM:SCALE?”
HISTogram:STDDev?
Query :MEASURE:HISTogram:STDDev? [{HISTogram}]
Returns the standard deviation of the histogram. The source can be specified with the
optional parameter following the STDDev query. The HISTogram:STDDev? query only applies
to the histogram waveform.
Returned Format [:MEASure:HISTogram:STDDev] <value>[,<result_state>]<NL>
<value> is the standard deviation of the histogram. 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:HISTOGRAM:STDDEV?”
JITTer:DCD?
Query :MEASure:JITTer:DCD?
Returns the duty cycle distortion value measured on the current source.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments)
Returned Format [:MEASure:JITTer:DCD] <value><NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASure:JITTer:DCD?”
JITTer:DDJ?
Query :MEASure:JITTer:DDJ?
Returns the data-dependent jitter value measured on the current source.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments)
Returned Format [:MEASure:JITTer:DDJ] <value><NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASure:JITTer:DDJ?”
JITTer:DDJVsbit?
Query :MEASure:JITTer:DDJVsbit?
Returns definite-length block data. The data block contains DDJ values for each edge has
that been measured. DDJ values are returned for only the edge types specified by the com-
mand MEASure:JITTer:EDGE. Each DDJ value is 32-bit floating point (4 bytes). The data
block is followed by a terminator character, 0A hex (linefeed). The DDJ value has units of
time or unit interval as specified by the :MEASure:JITTer:UNITs command. Use the :MEA-
Sure:JITTer:EBITs? query to return the bit numbers. Use the :MEASure:JITTer:PATTern? query to return
the edge type values.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
