Error Detector DATA IN
SENSe[1]:EYE:HEIGht? <NR3>
This command interrogates the eye height found by the most recent search for the value of
data amplitude that puts the zero-to-one threshold level midway between the upper and
lower bounds at which the error ratio exceeds the threshold value set up by the
:EYE:THReshold command.
If the result is not available or the search was unsuccessful. then the number 9.91 x E+37
(Not-A-Number, NAN) will be returned.
SENSe[1]:EYE:THReshold <numeric value>
This command sets the threshold to be used in the determination of the edges of the eye.
INPut1:POLarity NORMal|INVerted
Sets the polarity of the detected data signal.
The *RST selection is NORMal.
INPut1:DELay <numeric value>
Sets the delay of the sampling of the data input relative to the active clock edge. The units
are in seconds. The value is rounded to the nearest one picosecond.
The *RST selection is 0 ps.
INPut1:TERMination <numeric value>
This node permits the input termination level to be set to 0 Volts (ground) or −2 Volts.
If input termination and zero-to-one threshold level are to be set up, then the input
termination should be set up first.
The *RST selection is 0 V.
