R&S FSL 3GPP Base Station Measurements (Option K72)
1300.2519.12 4.289 E-11
– Symbol EVM
Peak (%Pk) or average (%rms) of the results of the error vector magnitude
– Modulation Type
modulation type of an HSDPA channel (QPSK or 16QAM modulation)
Remote: CDP:RSUM EXT
Power
Activates the measurement of the 3GPP FDD signal channel power and opens a submenu. This
measurement is identical to the ACP measurement (see ACP softkey), the default settings are in
accordance with the 3GPP specifications:
Parameter Default setting
CP / ACP Standard W–CDMA 3GPP FWD
# of Adj Chan 0 (all adjacent channels deactivated)
The R&S FSL measures the unweighted RF signal power in a bandwidth of
22.0|84.3)1(5 =+=
MHzMHzf
BW
The power is measured in zero span using a digital channel filter of 5 MHz in bandwidth.
According to the 3GPP standard, the measurement bandwidth (5 MHz) is slightly larger than the
minimum required bandwidth of 4.7 MHz.
