List Sequencer Measurement Results
Results by SCPI
Three slightly different commands can be used to obtain measurement results. For all of these
commands, the subopcode 1, 2, and 3 determine how much of the total measurement result is returned:
all of it (1), only a pass/fail result for the sequence (2), or the first failing measurement, identified by
acquisition number, analysis step number, and bitmap number of the measurement. If no subopcode is
given, 1 is assumed.
NOTE For all of these commands, the subopcode 1, 2, and 3 determine how much of the total
measurement result is returned: all of it (1), only a pass/fail result for the sequence (2), or
the first failing measurement, identified by acquisition number, analysis step number, and
bitmap number of the measurement (3). If no subopcode is specified, 1 is assumed.
:FETCh:LSEQuencer[1]|2|3?
As the FETCh command only returns the results from the buffer, and does not initiate a sequence, this
command would be used to read results previously captured, or else would follow an
:INITiate:LSEQuencer command.
:READ:LSEQuencer[1]|2|3?
The READ command initiates the sequence and then returns the results.
:MEASure:LSEQuencer[1]|2|3?
The MEASure command presets the sequence and measurement parameters to their default values,
initiates the sequence, and then returns the results. In most cases, this is not useful in Sequence Analyzer
mode; the FETCh and READ commands are generally used to obtain sequence results.
NOTE Because it presets the sequence and measurement parameters to their default values, the
MEASure command is usually not useful in Sequence Analyzer mode; sequence results
are typically obtained using the FETCh and READ commands instead.
The same commands can be used more narrowly, to return only the results from a particular acquisition
within the sequence (specified by acquisition number):
:FETCh:LSEQuencer[1]:ACQuire[1]|2|3|4..512?
:READ:LSEQuencer[1]:ACQuire[1]|2|3|4..512?
:MEASure:LSEQuencer[1]:ACQuire[1]|2|3|4..512?
To narrow the focus even further, the commands can be used to return only the results from a particular
analysis interval (identified by analysis step number) within a particular acquisition:
:FETCh:LSEQuencer[1]:ACQuire[1]|2|...|512:ASTep[1]|2|...|1000?
:READ:LSEQuencer[1]:ACQuire[1]|2|...|512:ASTep[1]|2|...|1000?
:MEASure:LSEQuencer[1]:ACQuire[1]|2|...|512:ASTep[1]|2|...|1000?
