Statistical results are relevant in particular if the "Measurement Length" is measured repeatedly.
Page 13: Test Setup
® General Description R&S CMW-KM750/-KM751 TD-SCDMA RX Tests 3.2.1 Test Setup The downlink RF generator signal of the R&S CMW is fed to the input of the DUT. The R&S CMW measures the uplink signal. Most conveniently, a bi-directional connection with a single coax cable is used.
Page 14: Multi Evaluation List Mode
® General Description R&S CMW-KM750/-KM751 Multi Evaluation List Mode Select an ARB file (see above) and generate the TD-SCDMA downlink signal. ● Select an appropriate test mode, so that the UE loops back the received data, via a 12.2 kbps RMC or DTCH (like downlink signal).
Page 15 ® General Description R&S CMW-KM750/-KM751 Multi Evaluation List Mode One list mode measurement can cover up to 500 segments with in total up to 1600 sub- frames. Up to 6 uplink timeslots can be measured per subframe. In list mode the R&S CMW can measure modulation results and spectrum results. The measured quantities can be enabled or disabled individually for each segment.
Page 16 ® General Description R&S CMW-KM750/-KM751 Multi Evaluation List Mode inaccurate, e.g. because of signal reconfiguration at the UE. Furthermore retriggering from time to time can compensate for a possible time drift of the UE. The retrigger flag of the first segment of the measurement is always ignored (implicitly set to ON).
Page 17: Td-Scdma Signal Properties
® General Description R&S CMW-KM750/-KM751 TD-SCDMA Signal Properties 2. Open the configuration dialog and disable the list mode in section "Measurement Control". Global and list mode parameters The RF settings (expected power, RF frequency) and most of the "UE Signal Info" settings are special list mode settings.
Page 18 ® General Description R&S CMW-KM750/-KM751 TD-SCDMA Signal Properties TS0 is always allocated to the downlink, TS1 to the uplink. Timeslots 2 to 6 are divided between the two directions, separated by the switching point. By moving the switching point the ratio between uplink and downlink data rates can be adapted to increase the spectrum efficiency.
