On the left-hand side there is the constellation display which shows the signal
in a graphical constellation diagram. Here, the signal’s magnitude and phase is
shown in relation to the carrier.
RF Analyzer for power
With the Power option the RF Analyzer offers a measurement application which
can be used for calibrating a UE’s output power, which is an essential factor for
stabilizing transmission and ensuring efficient radio resource management in
WCDMA systems. The purpose of the power measurements performed is for
example to verify that the UE’s maximum output power corresponds to the
nominal maximum output power and tolerance required. An excessive maximum
output power can cause interference with other channels or systems. On the
other hand, if the UE’s maximum output power is too small, the coverage area
decreases. Both situations have an adverse effect on system capacity.
To gain access to this menu, push the [Power] marker tab while working in
Generator/Analyzer mode. This menu displays the results of the power measure-
ments of the RF signal received at the RF
IN/OUT connector while in nonsig-
naling mode.
The RF Analyzer for power takes measurements in non-call mode, without any
call processing functions. Any coupling loss table defined in the appropriate
menu will be used for asynchronous measurements as well. For further informa-
tion on the definition of coupling loss values refer to “Coupling Loss” on page 75
Before starting a measurement, the radio frequency to be measured on has to be
entered.
There are entry fields available for these parameters in the lower area of the
menu, just above the softkeys.
