SCPI Command Reference
:FETCh:IBERate?
Syntax
:FETCh:IBERate? ‘identifier’
Input
Parameters
‘identifier’: 'M*.DataIn1' or 'M*.DataIn2'
Description
This query returns the instantaneous bit error rate measured by the
addressed error detector. The response contains a timestamp, the location
and the measured BER.
(TimeStamp, “Location”, BER[, coding specific ratios])
Timestamp
: As timestamp the Unix epoch time is used; it is defined as
elapsed seconds, milliseconds etc., since 01.01.1970 UTC.
Location
: It is a string referred to the place the ratios are located. This
parameter is important if a group name is used as ‘Identifier’.
BER
: The instantaneous bit error ratio.
Additional counters for 8b10b coding:
• SymbolErrorRatio
• IllegalSymbolRatio
• DisparityErrorRatio
• FillerSymbolRatio
• FrameErrorRatio
Additional Ratios for 128/130 and 128/132 coding:
• BlockErrorRatio:
• FillerSymbolRatio:
• FrameErrorRatio:
Additional Counters for PAM-4 line coding
• Symbol Error Ratio
• Symbol0 Error Ratio
• Symbol1 Error Ratio
• Symbol2 Error Ratio
• Symbol3 Error Ratio
This query returns the present state.
This SCPI is applicable for M8041A, M8051A, M8061A, M8062A and
M8046A.
