Measure Commands
CGRade:CROSsing
Returned Format [:MEASure:CGRade:CRATio] <value>[,<result_state>]<NL>
<value> is the contrast ratio. 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:CGRADE:CRATIO? PERCENT”
CGRade:CROSsing
Command :MEASure:CGRade:CROSsing [{CHANnel<N> | FUNCtion<N> | CGMemory}]
Measures the crossing level percent of the current eye diagram on the color grade or gray
scale display. The data for color grade display is the same as for gray scale display. If the
source is not set, the lowest numbered signal that is on will be the source of the measure-
ment.
Mode Eye mode only. Ensure that the eye type is set to NRZ. See “DEFine” on page 18-11.
Query :MEASure:CGRade:CROSsing? [{CHANnel<N> | FUNCtion<N> | CGMemory}]
The query returns the crossing level percent of the current eye diagram on the color grade or
gray scale display.
Returned Format [:MEASure:CGRade:CROSsing] <value>[,<result_state>]<NL>
<value> is the crossing level. 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:CGRade:CROSsing?”
CGRade:DCDistortion
Command :MEASure:CGRade:DCDistortion <format>[,{CHANnel<N> | FUNCtion<N> | CGMemory}]
Measures the duty cycle distortion on the eye diagram of the current color grade or gray scale
display. The parameter specifies the format for reporting the measurement. The data for
color grade display is the same as for gray scale display. If the source is not set, the lowest
numbered signal that is on will be the source of the measurement. <format> is {TIME | PER-
Cent}.
Mode Eye mode only. Ensure that the eye type is set to NRZ. See “DEFine” on page 18-11.
Query :MEASure:CGRade:DCDistortion? <format> [,{CHANnel<N> | FUNCtion<N> | CGMemory}]
The query returns the duty cycle distortion of the color grade or gray scale display.
Returned Format [:MEASure:CGRade:DCDistortion] <value>[,<result_state>] <NL>
<value> is the duty cycle distortion. 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:CGRADE:DCDistortion? PERCENT”
CGRade:DCYCle
Command :MEASure:CGRade:DCYCle [<source>]
