Number of channels: Tx, Adj
Up to 18 carrier channels and up to 12 adjacent channels can be defined.
Results are provided for the Tx channel and the number of defined adjacent channels
above and below the Tx channel. If more than one Tx channel is defined, the carrier
channel to which the relative adjacent-channel power values should be referenced
must be defined (see "Reference Channel" on page 136).
Note: If several carriers (Tx channels) are activated for the measurement, the number
of sweep points is increased to ensure that adjacent-channel powers are measured
with adequate accuracy.
For more information on how the number of channels affects the measured powers,
see Chapter 7.2.4.2, "Channel Power Results", on page 128.

Reference Channel
The measured power values in the adjacent channels can be displayed relative to the
transmission channel. If more than one Tx channel is defined, define which one is used
as a reference channel.
Tx Channel 1 Transmission channel 1 is used.
Min Power Tx Channel The transmission channel with the lowest power is used as a reference channel.
Max Power Tx Chan-
nel
The transmission channel with the highest power is used as a reference channel
(Default).
Lowest & Highest
Channel
The outer left-hand transmission channel is the reference channel for the lower
adjacent channels, the outer right-hand transmission channel that for the upper
adjacent channels.
