Measurement configuration
To detect the start of the first RU correctly, configure appropriate trigger settings (for
example power trigger for the rising edge, no delay).
To measure the end of the last allocated RU and the "OFF Power (after)", configure the
resource allocation settings according to your signal properties. Configure a sufficient
number of measured slots (at least length of allocated resource units, including repeti-
tions).

Figure 3-15: TX measurement
The table provides an overview of statistical values obtained in the measured slot.
Other detailed views provide a subset of these values:
●
Resource allocation: Configured subcarrier allocation, see "No. of Subcarriers,
Start Subcarrier" on page 233
●
EVM, magnitude error ("MErr"), phase error ("PhErr"):
For the SC-FDMA data symbols (all symbols except reference symbol), RMS and
peak values are provided.
The DMRS value refers to the reference symbol (demodulation reference signal).
