Spectrum Analyzer
(Available if Option
006, Spectrum
Analyzer, is Fitted)
The spectrum analyzer allows you to view the mobile phone’s signal over a wide
dynamic range. It also allows you to view any adjacent interference which may
exist.
NOTE The spectrum analyzer can detect very low power signals where Active Cell and
even Test Mode cannot operate. Broken cable or connectors can be found using
this function.
Method
Select SPEC ANL in the cell control screen.
Selecting (1) provides access to other functions of the spectrum analyzer. These are:
• Main - the default screen has basic spectrum analyzer functions,
see Figure 2-12 on page 2-25.
• RF Gen - this controls the RF generator in the Agilent 8922M/S. The generator
signal can be fed back into the spectrum analyzer for signal confirmation. The
Aux RF OUT port should be connected to the RF In/Out, and the RF Output set
to “Aux RF OUT”.
NOTE If both the input and output are set to RF IN/OUT, large errors in measured signal
level will be seen.
• Marker - this screen allows you to control the marker for the input signal.
• Auxiliary - the auxiliary screen controls the inputs and the attenuator settings.
