a) Put the metal plate labeled "E" into the frame.
Figure 11-2: Mounting verification plates
b) Select "Normalize Reflection" to initiate a measurement.
c) Wait until the results are displayed.
d) Remove the metal plate from the frame.
The mean reflection should be around 0
dB.
2. Normalize the transmission and phase measurement.
a) Select "Normalize Transmission" to initiate a free-space measurement.
The resulting transmission attenuation should be at approximately 0 dB.
3. Verify the reflection and transmission measurement.
a) Put the glass-ceramic 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" (plastic) and "C" (plas-
tic).
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.
