The test setup for the power analysis in the
power versus frequency or power ver-
sus power
is as follows:
1. Connect the DUT (for example bandpass) to the RF output of the instrument and
the RF input of the R&S NRP-Zxx sensor (like the R&S NRP-Z21).
2. Connect the USB output of the R&S NRP-Zxx to the SENSOR connector of the
instrument.
3. Open the "NRP-Z Analysis" dialog in the "Level Control" block of the generator
4. Set up the measurement and scale diagram in the "Configure…" dialog (for exam-
ple fast measurement, 200 measurement points, range, x-axis and y-axis scale).
5. Trigger measurement by pressing the "Start" button in the "NRP-Z Power Analysis"
diagram.
6. If necessary, perform the further settings:
a) Set markers with the rotary knob. To access the markers, activate the "NRP-Z
Analysis Frequency / Marker" diagram view with the REARR key. The markers
are moved by means of the cursor and the roll key to the desired trace position.
Note:
To activate the "NRP-Z Analysis Frequency / Marker" view, see
on page 222. Repeat pressing the REARR key
until this view appears.
b) Store a hardcopy of the measurement results
on page 221 ("Save…" submenu).
c) Apply user correction. "Ucor" is also available for NRP-Z measurements (see
Chapter 5.4.7, "User Correction"
The diagrams below show the result of the above settings, an RF frequency range
of 1 to 6 GHz and the level range of -65 dB to 5 dB.
