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 7.3.6.3, "How to Configure
an MSR ACLR Measurement", on page 183.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:NAME[:CHANnel<ch>] on page 780
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 adjacent channels is also affected by:
●
The position of the first Tx channel in the first sub block
●
The position of last Tx channel in the last sub block
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:CENTer[:CHANnel<ch>] on page 769
Technology Used for Transmission ← Tx Channel Definition
The technology used for transmission by the individual channel can be defined for
each channel. The required channel bandwidth and use of a weighting filter are pre-
configured automatically according to the selected technology standard.
"GSM"
Transmission according to GSM standard
"W-CDMA"
Transmission according to W-CDMA standard
"LTE_xxx"
Transmission according to LTE standard for different channel band-
widths
"USER"
User-defined transmission; no automatic preconfiguration possible
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:TECHnology[:CHANnel<ch>]
on page 770
Tx Channel Bandwidth ← Tx Channel Definition
The Tx channel bandwidth is normally defined by the transmission technology stan-
dard. The correct bandwidth is predefined automatically for the selected technology.
Each Tx channel is defined independently of the others; automatic bandwidth configu-
ration for subsequent channels as in common ACLR measurements is not performed.
The bandwidth for each channel is indicated by a colored bar in the display.
Remote command:
[SENSe:]POWer:ACHannel:SBLock<sb>:BANDwidth[:CHANnel<ch>]
on page 768
Weighting Filters ← Tx Channel Definition
Weighting filters allow you to determine the influence of individual channels on the total
measurement result. For each channel, you can activate or deactivate the use of the
weighting filter and define an individual weighting factor ( "Alpha:" value).
