calculation and enable the calculation of the
results use the command
. The ranges indicated below apply to all results except
standard deviation results. The minimum for standard deviation results equals 0. The
maximum equals the width of the indicated range divided by two. Exceptions are
explicitly stated.
The values described below are returned by
FETCh
commands.

mands return limit check results instead, one value for each result listed below.
The values listed below in curly brackets {} are returned for each active segment:
{...}
seg 1
, {...}
seg 2
, ..., {...}
seg n
. The number of active segments n is determined by
.
The number to the left of each result parameter is provided for easy identification of the
parameter position within the result array.
Return values:
<1_Reliability>
. In list mode, a zero reliability indicator indi-
cates that the results in all measured segments are valid. A non-
zero value indicates that an error occurred in at least one of the
measured segments.
{<2_SegReliability>
0 | 3 | 4 | 8
The segment reliability indicates whether one of the following
exceptions occurred in this segment:
0:
No error
3:
Signal overflow
4:
Signal low
8:
Synchronization error
If a combination of exceptions occurs, the most severe error is
indicated.
<3_EVMRMS>
<4_EVMPeak>
Error vector magnitude RMS and peak value.
Range:
0 % to 100 %
Default unit: %
<5_MErrRMS>
Magnitude error RMS value.
Range:
0 % to 100 %
Default unit: %
<6_MErrPEAK>
Magnitude error peak value.
Range:
-100 % to +100 % (AVERage: 0% to 100 %, SDE-
Viation: 0 % to 50 %)
Default unit: %
