Measure Commands
CGRade:JITTer
Returned Format [:MEASure:CGRade:EWIDth] <value>[,<result_state>] <NL>
<value> is the eye width. If SENDvalid is ON, the <result_state> is returned with the mea-
surement 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:EWIDTH?”
CGRade:JITTer
Command :MEASure:CGRade:JITTer {PP | RMS} [,{CHANnel<N> | FUNCtion<N> | CGMemory}]
Measures the jitter at the eye diagram crossing point. The parameter specifies the format in
which the results are reported: peak-to-peak or RMS. The data for color grade display is the
same as for gray scale display. If the source is not set, the lowest numbered signal display that
is on will be the source of the measurement. The optional source argument can be a channel,
function, or color-grade memory. Use the CGMemory argurment in Eye mode only.
Mode Eye or Oscilloscope modes.
Query :MEASure:CGRade:JITTer? {PP | RMS} [,{CHANnel<N> | FUNCtion<N> | CGMemory}]
The query returns the jitter of the color grade display.
Returned Format [:MEASure:CGRade:JITTer] {PP | RMS} [,<result_state>] <NL>
<value> is the jitter. If SENDvalid is ON, the <result_state> is returned with the measure-
ment 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:JITTER? RMS”
CGRade:OFACtor
Command :MEASure:CGRade:OFACtor [<source>]
Measures the opening factor of the RZ (Return-to-Zero) eye diagram on the color graded dis-
play. If the source is not set, the lowest numbered signal display that is on will be the source
of the measurement. <source> is {CHANnel<N> | FUNCtion<N> | CGMemory}.
Mode Eye mode only. Ensure that the eye type is set to RZ. See “DEFine” on page 18-11.
Query :MEASure:CGRade:OFACtor? [<source>]
This query returns the opening factor of the color graded display.
Returned Format [:MEASure:CGRade:OFACtor] <value>[,<result_state>]<NL>
<value> is the opening factor. 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:OFACtor?”
CGRade:OLEVel
Command :MEASure:CGRade:OLEVel [<source>]
Measures the logic one level inside the eye window. If the source is not set, the lowest num-
bered signal display that is on will be the source of the measurement. <source> is {CHAN-
nel<N> | FUNCtion<N> | CGMemory}.
