The screenshot above shows margin results for the current trace. Corresponding mar-
gin results are displayed for all active traces (Current, Average, Maximum). In this con-
text, "Average" means "margins for average trace" and not "average values of margins
for current trace". "Minimum" means "margins for maximum trace" (resulting in mini-
mum margins).
The "Total TX power" in the table indicates the sum of the TX power of all component
carriers. For other table results, see
chapter 3.2.6.11, "Detailed Views: TX Measure-
ment and BLER" , on page 534.
For the parameters at the bottom, see chapter 3.2.6.14, "Common View Elements" ,
on page 536.
For query of the spectrum emission mask results via remote control, see:
●
chapter 3.5.3.20, "Spectrum Emission Results (Traces)" , on page 659

3.2.6.6 Detailed Views: Spectrum ACLR
The ACLR results are displayed in a diagram and as a table of statistical results.
Fig. 3-29: LTE Multi Evaluation: ACLR
The diagram shows the mean power in the assigned E-UTRA channel as central bar.
The other bars indicate the mean powers in the first adjacent E-UTRA channels and in
the first and second adjacent UTRA channels. All values are absolute power levels in
dBm.
With carrier aggregation, an E-UTRA channel comprises the aggregated bandwidth
minus a guard band. The figure shows a measurement with carrier aggregation and a
channel bandwidth of 20 MHz for PCC and SCC. The width of an E-UTRA bar is 38
MHz.
