Transmission measurement
This measurement yields the transmission characteristics of a two-port network. The
internal or external tracking generator serves as a signal source. It is connected to the
input connector of the DUT. The input of the R&S
ESR is fed from the output of the
DUT. A calibration can be carried out to compensate for the effects of the test setup
(e.g. frequency response of connecting cables).

Reflection measurement
Scalar reflection measurements can be carried out by means of a reflection-coefficient
measurement bridge.

Normalization
The "NORMALIZE" softkey switches normalization on or off. The softkey is only availa-
ble if the memory contains a correction trace.
You can shift the relative reference point within the grid using the
on page 478 softkey. Thus, the trace can be shifted from the top grid margin
to the middle of the grid:
