SCPI Command Reference
:PLUGin:OTIMing:FETCh[:JITTer][:TOTal][:RMSquare]?
Syntax
:PLUGin:OTIMing:FETCh[:JITTer][:TOTal][:RMSquare]?
‘identifier’[,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[‘Location’]: Specify location (optional).
Return Range
<NR3>
Description
This command returns the average of the left and right jitter histogram
root mean squared values associated with a specific measurement name
identifier.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
A measurement run on a location identifier (for example, ‘M1.DataIn1’) will
return following result.
Example
:PLUG:OTIM:FETC? ‘MyOutputTiming’,‘M1.DataIn1’
:PLUGin:OTIMing:FETCh[:JITTer][:TOTal]:RANDom[:RMSquare]?
Syntax
:PLUGin:OTIMing:FETCh[:JITTer][:TOTal]:RANDom[:RMSquare]?
‘identifier’[,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[‘Location’]: Specify location (optional).
Return Range
<NR3>
Description
This command returns the total jitter component with Gaussian
distribution associated with a specific measurement name identifier. After
transforming a contiguous range of measured points into Q space and
performing a linear regression, it is calculated as the mean of the sigmas of
the two straight lines. The contiguous range is limited by the BER
threshold and the minimum BER for RJ/DJ separation threshold.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
A measurement run on a location identifier (for example, ‘M1.DataIn1’) will
return following result.
Example
:PLUG:OTIM:FETC:RAND? ‘MyOutputTiming’,‘M1.DataIn1’
