C
Calibration:
Determines reproducible system characteristics and reduces the corre-
sponding measurement deviations, thus increasing measurement accuracy signifi-
cantly.
The calibration set is available as accessory (R&S
QAR-Z30).
D
DUT:
Device under test. For the R&S
QAR, the DUT is usually a radome or a bumper.
M
Mean reflection:
Mean value of the reflection measured in the analyzed area of the
DUT.
A low mean reflection corresponds to a high transparency of the DUT.
Measurement software:
Software to configure, control and run measurements with
the R&S
QAR.
The software is installed on the R&S
QAR.
Mounting table:
Pedestal that holds the
Available as accessory (R&S
QAR-Z50).
N
Normalization:
Process that takes the current measurement results as a reference
and subtracts them from subsequent measurement results.
Normalization object:
A shiny metal plate required for the normalization of the reflec-
tion measurement.
O
OLE:
Object linking and embedding
OPC:
OLE for process control
P
Platform:
Flat plate where to fix the R&S
QAR and its accessories.
Available as accessory (R&S
