Sub block Center Frequency ← 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 (CACLR).
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:FREQuency:CENTer on page 718
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 (CACLR).
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:RFBWidth on page 719
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 720
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.
The Tx channel settings for the individual sub blocks are configured in individual sub-
tabs of the "Tx Channel Settings" tab.
For details on configuring MSR Tx channels see chapter 5.3.6.3, "How to Configure an
MSR ACLR Measurement", on page 174.
Note: Channel names. In MSR ACLR measurements, Tx channel names correspond
to the specified technology (for LTE including the bandwidth), followed by a consecu-
tive number. (If the channel is too narrow to display the channel name, it is replaced by
"..." on the screen.) Channel names cannot be defined manually. The assigned sub
block (A,B,C,D,E) is indicated with the channel name (e.g. B:LTE_5M1).
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:NAME[:CHANnel<ch>]? on page 718
Tx Center Frequency ← Tx Channel Definition
Defines the (absolute) center frequency of an MSR Tx channel. Each Tx channel is
defined independently of the others; automatic spacing as in common ACLR measure-
ments is not performed.
Note that the position of the first Tx channel in the first sub block and the last Tx chan-
nel in the last sub block also affect the position of the adjacent channels.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:CENTer[:CHANnel<ch>] on page 718
