For details on MSR signals, see Chapter 7.3.3.4, "Measurement on Multi-Standard
Radio (MSR) Signals", on page 153.
For details on setting up channels, see Chapter 7.3.6.3, "How to Configure an MSR
ACLR Measurement", on page 183.
The Tx channel settings for the individual sub blocks are configured in individual sub-
tabs of the "Tx Channel Settings" tab.

Sub Block Definition
Sub blocks are groups of transmit channels in an MSR signal. Up to five sub blocks
can be defined. They are defined as an RF bandwidth around a center frequency with
a specific number of transmit channels (max. 18).
Sub blocks are named A,B,C,D,E and are indicated by a slim blue bar along the fre-
quency axis.
Sub Block / Center Freq ← Sub Block Definition
Defines the center of an MSR sub block. Note that the position of the sub block also
affects the position of the adjacent gap channels.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:FREQuency:CENTer on page 769
RF Bandwidth ← Sub Block Definition
Defines the bandwidth of the individual MSR sub block. Note that sub block ranges
also affect the position of the adjacent gap channels.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:RFBWidth on page 770
Number of Tx Channels ( Tx Count ) ← Sub Block Definition
Defines the number of transmit channels the specific sub block contains. The maxi-
mum is 18 Tx channels.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:TXCHannel:COUNt on page 771
Tx Channel Definition
As opposed to common ACLR channel definitions, the Tx channels are defined at
absolute frequencies, rather than by a spacing relative to the (common) center fre-
quency. Each transmit channel can be assigned a different technology, used to prede-
fine the required bandwidth.
