F3 Initiates a reflection normalization
F4 Initiates a transmission normalization
F5 Initiates a measurement.
5.1.3 Measurements
The R&S QAR provides several measurement types: reflection measurements and
transmission measurements. Transmission measurements require the optional trans-
mitter module. Both measurements usually consist of two steps, normalization and the
actual measurement.
Measuring a DUT
1. Set up the normalization.
2. Start the normalization with "Normalize Reflection" (or the F3 key) and "Normalize
Transmission" (or the F4 key).
For details on how to normalize the measurement, see
Chapter 5.1.3.1, "Normali-
zation" , on page 41.
3. Place the DUT in front of the R&S QAR, for example on the optional mounting
table.
4. Start the reflection and transmission measurement with "Measure" (or the F5 key).
The measurement itself lasts less than a second. The results are displayed after a
few seconds.
For details on how to run the measurement, see
Chapter 5.1.3.2, "Reflection Mea-
surement" , on page 43 and Chapter 5.1.3.3, "Transmission Measurement" ,
on page 43.

5.1.3.1 Normalization
Normalization is a separate measurement that determines systematic, reproducible
measurement deviations. Determining these measurement deviations allows you to
