CALCulate:EVDO:MEAS<i>:MEValuation:LIST:OBW:CURRent?
FETCh:EVDO:MEAS<i>:MEValuation:LIST:OBW:CURRent?
Returns Occupied Bandwidth (OBW) results in list mode.
To define the calculation and enable the calculation of the results use the command
CONFigure:EVDO:MEAS<i>:MEValuation:LIST:SEGMent<no>:MODulation
.
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
CONFigure:EVDO:MEAS<i>:MEValuation:LIST:COUNt
.
The values described below are returned by
FETCh
and
READ
commands.
CALCulate
commands return limit check results instead, one value for each result listed below.
The number to the left of each result parameter is provided for easy identification of the
parameter position within the result array.
The values described below are returned by the
FETCh
command. The
CALCulate
command returns limit check results instead, one value for each result listed below.

chapter 3.2.8, "Multi Evaluation Measurement Results"
Return values:
<1_Reliability>
Conventions and General Information
. In list mode, a zero relia-
bility indicator indicates that the results in all measured seg-
ments are valid. A non-zero value indicates that an error occur-
red 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_OBW>
Occupied bandwidth
Range:
0 to 16 MHz (SDEViation 0 to 8 MHz)
Default unit: MHz
<4_LowerEdge>,
<5_UpperEdge>}
Lower and upper edge of the selected carrier's or carrier group's
occupied bandwidth.
For single-carrier configurations the lower and upper edges are
returned as frequency offsets w.r.t. the carrier's center fre-
quency. For multi-carrier configurations absolute frequency val-
ues are returned.
Range:
- 16 to 6000 MHz
Default unit: MHz
