Graphically representing power versus time (Scope mode)
In the
Scope
mode, power versus time can be represented graphically as with an oscilloscope. If you
wish to carry out time-dependent measurements (in the Burst or Timeslot mode) on modulated signals,
displaying the signal in the Scope mode is always initially recommended since stable triggering by the
R&S NRP is most clearly recognized in this mode.

Setting the Scope mode.
¾
Connect a power sensor of the R&S NRP-Z1x or
R&S NRP-Z2x family to connector A of the R&S NRP
and apply an amplitude-modulated or pulsed signal
having a modulation or pulse frequency of approx.
1
kHz. The maximum level should be between
–10 dBm and +10 dBm.
