2.3.1 Setup Configurations – Single-Side

The measurement requires a DUT in a solo configuration. The setup is ready to connect a Spectrum Signal Analyzer or Oscilloscope to measure parameters like the TX power (on Physical TX calibrations) or the background noise (on a Noise Test).

There are two different configurations of the setups:

  • Configuration A. DUT connected to CENELEC CISPR16-1 LISN. See Figure 2-3.
  • Configuration B. DUT connected to PRIME Adaptation LISN. See Figure 2-4.

Both of these setup configurations are described in the next figures.

It is advisable at the input of the Spectrum Signal Analyzer, to include a pulse limiter that protects the measuring receiver’s input against high RF input levels and high-energy interfering pulses, for example, when the DUT is switched on and off. Additionally, a characterized 20 dB attenuator must be included to reduce the signal level that reaches the pulse limiter.
