The limits for the normalization of the reflection measurement are universal, not
device-specific.
3. Verify the reflection measurement.
a) Put the metal plate with cut-outs labeled D into the frame.
b) Initiate a measurement.
c) Remove the metal plate from the frame.
The resulting image should show a clear image of the verification object. The
patterns should be clearly visible.
Verification OK
Verification not OK
4. If you are using the transmitter module:
Normalize the transmission measurement.
a) Remove all objects in front of the R&S
QAR (except for the table and the
frame).
b) Select "Normalize Transmission" to initiate a free-space measurement.
The resulting trace should be a straight line at approximately 0
dB attenuation.
5. If you are using the transmitter module:
Verify the transmission measurement.
a) Put the plastic plate labeled A into the frame.
b) Initiate a measurement.
c) Remove the plastic plate from the frame.
d) Do the same for the other two plastic plates labeled B and C.
After each measurement, check the mean transmission loss against the limits a
77
and a
81
specified on the stickers attached to the verification plates. The sticker
shows the attenuation characteristics of the plate and the deviation the result may
have.
Each sticker contains two values.
