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
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
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
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.
