R&S FSL 3GPP Base Station Measurements (Option K72)
1300.2519.12 4.287 E-11
If the HSDPA/HSUPA On/Off softkey is activated, the detection of channels does not depend on
pilot sequences. An active channel merely has to exceed the minimum power (see Inactive
Channel Threshold softkey). Therefore channels of the type HS–PDSCH are recognized as
active (see also Code Dom Channel Table softkey).

Code Dom Result Summary
Opens a submenu to display the Result Summary.
Result Summary Normal
Selects the mormal Code Domain Result Summary result display.
This result display shows the most important measurement results in one table with big letters.
Via the Result Summary Extended softkey you can switch to the extended Code Dom Result
Summary result display.
– Total Power
total signal power (average power of total evaluated 3GPP FDD frame).
– Carrier Frequency Error
frequency error relative to the center frequency of the R&S FSL
The absolute frequency error is the sum of the R&S FSL and DUT frequency error. The
specified value is averaged via one slot; the frequency offset of the selected slot applies (via
Select CPICH Slot softkey). The maximum frequency error that can be compensated is
specified in the table below as a function of the sync mode. Transmitter and receiver should be
synchronized as far as possible (see chapter 2).
Sync Type Antenna diversity Max. Freq. Offset
CPICH X 5.0 kHz
SCH OFF 1.6 kHz
SCH ANT 1 330 Hz
SCH ANT 2 330 Hz
– Composite EVM
difference between the test signal and the ideal reference signal
– Peak Code Domain Error
projection of the difference between the test signal and the ideal reference signal onto the
selected spreading factor
– No of Active Channels
number of active channels detected in the signal (Both the detected data channels and the
control channels are considered active channels.)
