READ:SPURious Subsystem
This subsystem provides the commands for starting measurements in the GSM BTS (option FSE-K11)
and GSM MS (option FSE-K10) Analyzer mode, which are used to measure the power of spurious
emissions, and for reading out the results subsequently.

:READ:SPURious[:ALL]?
This command starts the measurement of the spurious emissions of the base station or mobile and
reads out the result. The measurement is performed in the currently set frequency range.
Parameter: The result is read out as a list of partial ASCII result strings separated by ’,’ in the
following format:
<Index>,<Freq1>,<Freq2>,<Level>,<Limit>, <Abs/Rel>,<Status> [,
<Index>,<Freq1>,<Freq2>,<Level>,<Limit>, <Abs/Rel>,<Status>]...
where the part set in ’[...]’ characterizes a partial result string which can be repeated n times.
<Index>: 0, if the partial result string characterizes a
measurement range.
current number <>0,
if the partial result string characterizes a
single limit excess.
<Freq1>: Start frequency of the measurement range or frequency where
the limit is exceeded.
<Freq2>: Stop frequency of the measurement range or frequency where
the measured range is exceeded. The value of <Freq2> is
equal to the value of <Freq1>, if either the measurement is
performed in the time domain or the partial result string contains
a limit excess.
<Level>: Measured maximum level of the partial range or measured level
at the test point.
<Limit>: Limit in the partial range or at the test point.
<Abs/Rel>: ABS <Level> and <Limit> are in absolute units (dBm)
REL <Level> and <Limit> are in absolute units (dBm)
<Status>: Result of the limit check in character data form:
PASSED no limit exceeded
FAILED limit exceeded
MARGIN margin exceeded
