SCPI Command Reference
:PLUGin:OTIMing:FETCh:EDGE[:LEFT][:POINts]?
Syntax
:PLUGin:OTIMing:FETCh:EDGE[:LEFT][:POINts]? ‘identifier’[,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[‘Location’]: Specify location (optional).
Return Range
<NR3>
Description
This command returns the number of points that have been measured
between the BER Threshold and the Min. BER for RJ/DJ separation
threshold associated with a specific measurement name identifier. It is
calculated for left slope (left edge). This number has to be greater than 2
for the RJ, DJ and estimated TJ values to be applicable.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
A measurement run on a location identifier (for example, ‘M1.DataIn1’) will
return following results.
Example
:PLUG:OTIM:FETC:EDGE? ‘MyOutputTiming’,‘M1.DataIn1’
:PLUGin:OTIMing:FETCh:EDGE[:LEFT]:RSQuare?
Syntax
:PLUGin:OTIMing:FETCh:EDGE[:LEFT]:RSQuare? ‘identifier’[,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[‘Location’]: Specify location (optional).
Return Range
<NR3>
Description
This command returns the R^2 values calculated for left slope of the
bathtub curve (left edge) associated with a specific measurement name
identifier. They are a measure of how well the transformed points between
BER Threshold and Min. BER for RJ/DJ Separation fit to the linear
regression. They have to be greater than 0.75 for the RJ, DJ and estimated
TJ values to be applicable.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
A measurement run on a location identifier (for example, ‘M1.DataIn1’) will
return following results.
Example
:PLUG:OTIM:FETC:EDGE:RSQ? ‘MyOutputTiming’,‘M1.DataIn1’
