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 152).
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 5.3.2, "Channel Power Results" , on page 136.

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, you must select which
one is to be used as a reference channel.
Tx Channel 1 Transmission channel 1 is used.
(Not available for MSR ACLR)
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.
