Number of Sub Blocks
Defines the number of sub blocks, i.e. groups of transmission channels in an MSR sig-
nal.
For more information, see Chapter 7.2.3.4, "Measurement on Multi-Standard Radio
(MSR) Signals", on page 162.
Remote command:
[SENSe:]POWer:ACHannel:SBCount on page 860
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.
(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.

Noise Cancellation
The R&S FSW can correct the results by removing the inherent noise of the analyzer,
which increases the dynamic range.
In this case, a reference measurement of the inherent noise of the analyzer is carried
out. The measured noise power is then subtracted from the power in the channel that
is being analyzed (first active trace only).
