FETCh:NIOT:MEAS<i>:MEValuation:SEMask:MARGin:MINimum:POSitiv?
Returns spectrum emission mask margin results. A negative margin indicates that the
trace is located above the limit line, i.e. the limit is exceeded.
The individual commands provide results for the
CURRent
,
AVERage
and maximum
traces (resulting in
MINimum
margins), for
NEGative
and
POSitive
offset frequen-
cies.
Each command returns pairs of X and Y values of the margins for emission mask
areas 1 to 12. Result array structure:
<Reliability>, <OutOfTolerance>, {<MarginX>, <MarginY>}
area 1
, {...}
area 2
, ..., {...}
area 12
For inactive areas, NCAP is returned.
Return values:
<Reliability>
<OutOfTolerance>
Out of tolerance result, i.e. percentage of measurement inter-
vals of the statistic count for spectrum emission measurements
exceeding the specified spectrum emission mask limits.
Default unit: %
<MarginX>
X-position of margin
Default unit: Hz
<MarginY>
Y-value of margin
Default unit: dB
