5 SCPI Command Reference
:PLUGin:OTIMing:EVALuation:BERThresh[?]
Syntax :PLUGin:OTIMing:EVALuation:BERThresh ‘identifier’, <NRf>
:PLUGin:OTIMing:EVALuation:BERThresh? ‘identifier’
Input
Parameters
‘identifier’: Specify the measurement name.
<NRf>: Specify the BER threshold value.
Return Range 1E-15 to 1E-1
Description This command specifies the BER threshold value used to calculate the
measurement parameters and associates it with a specific measurement
name identifier. The query returns the current BER threshold value.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example :PLUG:OTIM:EVAL:BERT ‘MyMeasurement’, 1E-10
:PLUGin:OTIMing:EVALuation:MBJPartition[?]
Syntax :PLUGin:OTIMing:EVALuation:MBJPartition ‘identifier’, <NRf>
:PLUGin:OTIMing:EVALuation:MBJPartition? ‘identifier’
Input
Parameters
‘identifier’: Specify the measurement name.
<NRf>: Specify the minimum BER for separating random and deterministic
jitter components.
Return Range 1E-18 to 1E+0
Description This command specifies the minimum BER value for separating the
random and deterministic jitter components and associates it with a
specific measurement name identifier. In order to separate the random
and deterministic jitter from the bathtub, the specified BER threshold value
must be greater than the value specified by this command. The range is
1E-18 to 1E+0. The query returns the minimum value specified to separate
the random and deterministic jitter components. The default is 1E-9.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example :PLUG:OTIM:EVAL:MBJP ‘MyMeasurement’, 1E-7
