:SYSTem:INSTrument:LTRaining:EQUalization[:STATus]?
Syntax :SYSTem:INSTrument:LTRaining:EQUalization[:STATus]? ‘identifier’
Input
Parameters
‘identifier:’ 'M*.DataOut1' or 'M*.DataOut2'
Description This query returns the Dut transmitter equalization information from the
link up block. The results are combined to an expression. An expression is
comparable to a struct in a programming language. It’s a set of parameter
of different types separated by a comma and enclosed by parenthesis.
The returned expression contains the location and a set of values.
(“Location”, Accepted, PreCursor, MainCursor, PostCursor, FullSwing,
LowFrequency)
Location: It’s a string referred to the place the Dut tx equalization
information is located. In this case its either M*.DataOut1 or M*.DataOut2.
This parameter is important if a group name is used as ‘identifier’.
Accepted: Requested coefficients are accepted or rejected, either 0 or 1.
PreCursor: Received pre-cursor coefficient value during Phase 2 or 3 of the
equalization. If no data is present, 9.91 E 37 is returned.
MainCursor: Received data-cursor coefficient value during Phase 2 or 3 of
the equalization. If no data is present, 9.91 E 37 is returned.
PostCursor: Received post-cursor coefficient value during Phase 2 or 3 of
the equalization. If no data is present, 9.91 E 37 is returned.
FullSwing: Full swing value received during Phase 1 of the equalization. If
no data is present, 9.91 E 37 is returned.
LowFrequency: Low Frequency value received during Phase 1 of the
equalization. If no data is present, 9.91 E 37 is returned.
If this query is sent to a ‘group’ of inputs the response will be expanded by
additional sets of counted values. The expression contains for every input
belonging to a group a separate set of values starting with the location.
