Start Continuous / Stop
Starts and stops the power analysis measurement. Depending on the selected mea-
surement mode, the label varies.
8.4.4.4 Test setup example
As a power meter has no built-in selection, it is measuring all signal components from
nearly DC to 40 GHz and higher. Therefore, the DUT's signal must be rather pure or
subjected to external filtering (harmonics, spurious) before measured.
The test setup for the power analysis in the power versus frequency or power versus
power is as follows:
Figure 8-7:
DUT = Device under test
PS = Power sensor, e.g. R&S NRP-Z8x, connected at the DUT's input and the USB connector of the
R&S SMA100B
1. Connect the DUT RF input to the RF output of the instrument.
2. Connect the DUT RF output to the power sensor.
3. Connect the power sensor to the signal generator.
4. Select "Clk Syn/Power Sens" > "NRP-Z Power Analysis".
5. Select "Configure" to open a dialog for setting up the measurement.
6. Select the power sensor, indicated at the bottom of the dialog to set the trace.
7. Select "Start Cont." to trigger the measurement.
