DC power measurement
For the R&S ZNB/ZNBT an external power supply is required to measure P
DC
.
The DC power P
DC
supplied to the DUT can be measured using one or two of the four
DC inputs DC INPUT 1...4 at the rear panel (option R&S ZNB/ZNBT-B81). The Power
Added Efficiency dialog suggests different measurement types involving different test
setups. The measurement types depend on the properties of the DC power supply
(constant current I
0
or constant power U
0
) and an optional precision resistor R used to
measure the DC current. Depending on the measurement type, one or two of the val-
ues I
0
, U
0
, and/or R must be entered as parameters of the PAE calculation.
