14.4.2.2 Configuring consumption measurements
For details of the configuration settings, see Chapter 14.4.2.3, "Consumption settings" ,
on page 351.
1. Press the Apps Selection key. Tap "Power Analysis".
2. In the "Input" tab, tap "Consumption".
3. Connect the differential voltage probe and the current probe to the oscilloscope.
It is recommended that you use a high-voltage differential probe for measurements
at the DUT power input.
4. Demagnetize the current probe. For details, see the user manual of your current
probe.
5. Select the "Tools" tab.
6. Connect the probes to the R&S RT-ZF20 power deskew fixture.
7. "Deskew" the probes and adjust the "Zero Offset".
8. Disconnect the probes from the R&S RT-ZF20 power deskew fixture.
9. Connect the probes to the DUT:
● Connect the positive (+) signal socket of the differential voltage probe to the
line of the AC input.
● Connect the negative (-) signal socket of the differential voltage probe to the
neutral of the AC input. Make sure that you use a common ground.
● Connect the current probe in flow direction of the current to the line of the AC
input.
10. Close the "Power Analysis".
11. Press the "Menu" button and scroll to the "Power" menu.
12. Select the correct channels for the "Current" and the "Voltage" sources.
13. Press the Autoset button to adjust the display scales automatically or adjust them
manually.
On the screen you can see the measurement waveforms of the current, the voltage
and the power. Also, the numeric measurement results are shown in the lower left
corner. For details, see
Chapter 14.4.2, "Consumption" , on page 350.
