SCPI Command Reference 5
:INPut:ALIGnment:EYE:TCEN
Syntax :INPut:ALIGnment:EYE:TCEN ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2' or M*DataIn
Description This command initiates a search for the value of data/clock delay that puts
the active clock edge in the center of the data eye, midway between the
two relative delay points with a measured BER just in excess of the BER
configured by the :EYE:THReshold command. If successful, the command
leaves the data/clock delay at this value.
This SCPI is applicable for M8041A, M8051A and M8046A.
Example :INP:ALIG:EYE:TCEN ‘M1.DataIn1’
:INPut:ALIGnment:EYE:ABORt
Syntax :INPut:ALIGnment:EYE:ABORt ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2' or M*DataIn
Description This command interrupts and aborts an alignment.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example :INP:ALIG:EYE:ABOR ‘M1.DataIn1’
:INPut:ALIGnment:EYE:THReshold[?]
Syntax :INPut:ALIGnment:EYE:THReshold ‘identifier’, <NRf>
:INPut:ALIGnment:EYE:THReshold? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1', 'M*.DataIn2' or M*DataIn
<NRf>: Set BER threshold.
Return Range 1E-9 to 1E-1
Description The command sets the BER threshold to be used in the determination of
the edges of the eye. The query returns the current BER threshold value.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example :INP:ALIG:EYE:THR ‘M1.DataIn1’, 1E-3
