16.5.4 Power efficiency
This measurement requires a 4-channel oscilloscope (R&S RTExxx4).
"Power Efficiency" analysis measures the input and the output power of a power sup-
ply. The power efficiency of the power supply is then calculated as the ratio of the out-
put power and the input power.
Required probes:
●
Two differential voltage probes
●
Two current probes
16.5.4.1 Power efficiency results
The results of "Power Efficiency" measurements are provided in two ways:
●
The diagram shows the graphical presentation of:
– the voltage input waveform
– the current input waveform
– the voltage output waveform
– the voltage input waveform
– the power input waveform
– the power output waveform
●
The result box displays the numeric measurement results of the "Input power",
"Output power" and the "Efficiency". For a detailed description, see Table 16-2.
