Ch Power ACLR
Activates the active channel or adjacent-channel power measurement either for a sin-
gle carrier signal or for several carrier signals, depending on the current measurement
configuration, and opens a submenu to configure the channel power measurement.
With default settings the measurement is performed by integrating the powers at the
display points within the specified channels (IBW method).
If several TX cahnnels (carriers) are activated, the number of measured values is
increased to ensure that adjacent-channel powers are measured with adequate accu-
racy.
For general information on performing channel or adjacent-channel power measure-
ments, see
Chapter 6.1.1.2, "Measuring Channel Power and Adjacent-Channel
Power" , on page 225.

CP/ACLR Standard ← Ch Power ACLR
Opens an edit dialog box to select the settings according to predefined standards. For
details on the available standards see
"Predefined CP/ACLR Standards" on page 246.
By default no standard is set.
The selection of the standard influences the following parameters (see "Optimized Set-
tings for CP/ACLR Test Parameters" on page 247):
●
channel spacing and adjacent-channel spacing
●
channel bandwidth, adjacent-channel bandwidth, and type of filtering
●
resolution bandwidth
●
video bandwidth
●
detector
●
# of adjacent channels
●
trace averaging (switched off)
