R&S FSH Digital Modulation Analyzer
Measurements on LTE Signals
Operating Manual 1173.6275.12 - 30 311
9.8.1.2 Global Results
Global results contain various measurement results of the composite signal. These
results evaluate the total signal over the period of one frame. The global results also
contain information about the quality of the measured signal of up to one frame. The
exact amount of data that is analyzed depends on the number of selected subframes.
RF Channel Power
Shows the total power of the currently measured LTE signal.
The channel power includes all subcarriers covered by the channel bandwidth. Signal
power outside the channel bandwidth is not included in the total power, even if it is
visible in the spectrum overview.
In case of over-the-air measurements, the total power includes all received signals in
the channel bandwidth.
Overall EVM
Shows the overall EVM of the signal.
The overall EVM includes all signal components, regardless of the modulation or
channel type.
Carrier Freq Error
Shows the frequency error in relation to the current center frequency of the R&S FSH.
For more information see "Selecting the Unit of the Carrier Frequency Error" on page
323.
Concerning uncertainty of the reference frequency of the GPS receiver, refer to the
data sheet.
Sync Signal Power
Shows the power of the synchronization signal.
For more information see "Selecting the Synchronization Signal" on page 323.
OSTP
Shows the OSTP of the signal.
RSRP (3GPP TS 36.214)
Shows the Reference Signal Received Power (RSRP).
The RSRP is the average power of the cell-specific reference signals. It is calculated
over all subcarriers and the complete channel bandwidth.
Note that the R&S FSH bases its calculation of the RSRP on the channel bandwidth
you have selected for measurement, not the channel bandwidth it actually receives.
