Channel power results
The Result Summary for MRS signal measurements is similar to the table for common
signals (see
chapter 5.3.2, "Channel Power Results"
channel results are grouped by sub blocks, and sub block totals are provided instead
of a total Tx channel power. Instead of the individual channel frequency offsets, the
absolute center frequencies are indicated for the transmit channels. The CACLR
results for each gap channel are appended at the end of the table. The CACLR results
are calculated as the power in the CACLR channel divided by the power sum of the
two closest transmission channels to either side of it.
Restrictions and dependencies
As the signal structure in multi-standard radio signals may vary considerably, the chan-
nels can be defined very flexibly for the ACLR measurement with the R&S
FSW. No
checks or limitations are implemented concerning the channel definitions, apart from
the maximum number of channels to be defined. Thus, you will not be notified if trans-
mit channels for a specific sub block lie outside the sub block's defined frequency
range, or if transmit and CACLR channels overlap.
5.3.4 Channel Power Configuration
Channel Power (CP) and Adjacent-Channel Power (ACLR) measurements are
selected via the "Channel Power ACLR" button in the "Select Measurement" dialog
box. The measurement is started immediately with the default settings. It can be con-
figured via the MEAS CONFIG key or in the "ACLR Setup" dialog box, which is dis-
played when you select the "CP/ACLR Config" softkey from the "CH Power" menu.
If the "Multi-Standard Radio" standard is selected (see
on page 150), the
"ACLR Setup" dialog box is replaced by the "MSR ACLR Setup" dialog box. See
ter 5.3.5, "MSR ACLR Configuration"
on page 158 for a description of these settings.
