About the channel power mode
The 9102 offers different measurement modes, e.g. spectrum analysis
and channel power measurements. The channel power mode allows
you to measure the radiated power within a certain frequency band
with a single button press. This mode reduces the complexity of all the
setup possibilities for defined communication systems. Several
communication systems are predefined in the 9102 or can be down-
loaded from a PC using the 9100 Data Exchange Software; see section
“Managing communication systems for channel power measurements”
on page 245 for more details.
Within channel power mode, three different frequency-selective types
of power measurements are supported, for details on selecting the
measurement type refer to “Selecting the measurement mode” on
page 85:
– Channel power
– Adjacent channel power ratio (ACPR)
– Occupied bandwidth (OBW)
These measurement types are available both in channel power and in
spectrum analysis mode. However, in contrast to the spectrum analysis
mode, which looks at the power level at a certain frequency, the
channel power mode uses a system approach. A system consists of
several channels, each channel has a unique channel number assigned
to it. Within a system the channels have the same bandwidth and
channel spacing. Depending on the system the channels may overlap,
follow each other directly or be separated by spaces.
In order to distinctly specify a system the following parameters have to
be set on the 9102:
– First channel
– Last channel
– Channel width
– Channel spacing
– First frequency
