used components, such as losses due to cables, modules or components like power
amplifiers, and compensate these effects accordingly.

Figure 5-3: Example of a test setup with NRP-Z Level Control
As shown in the example, the sensor measures a proportional power in defined time
intervals, derivated from a coupler. It considers optionally given S-parameters and
returns the results to the generator. The signal generator compares the measured level
with the set value and adjusts its output level accordingly.
This allows you to control the external signal level continuously and reliably reach a
constant input level at the DUT in real time.
