R&S FSH
Digital Modulation Analyzer
Measurements on TD-SCDMA Signals
Operating Manual 1173.6275.12 - 30
294
Switching Point
Shows the switching point in a subframe that separates uplink and downlink.
For more information see "
Slot Number
Shows the time slot (0 to 6) of the TD-SCDMA subframe that is currently analyzed.
For more information see "
Max Users
Shows the maximum number of midamble shifts in a cell. Because each midamble is
user-specific, the midamble shifts also define the number of users that can be served
in one cell.
Channel Phases
Shows the phase characteristics of the code channels.
For more information see "
Selecting the Phase Characteristics of the Code Channels
on page 307.
9.7.1.2 Global Results
Global results contain various measurement results of the composite signal. These
results evaluate the total signal over the period of one slot. The global results also
contain information about the quality of the measured signal.
Note that some results are only evaluated if the channel search has been turned on.
For more information see "
RF Channel Power
Shows the total power of the currently measured TD-SCDMA signal.
Note that the RF Channel Power shown in the Result Summary is measured over one
time slot. The RF Channel Power shown in the Spectrum Overview is measured over
one complete subframe.
In case of over-the-air measurements, the total power includes all received signals in
the channel bandwidth.
Carrier Freq Error
Shows the frequency error in related to the current center frequency of the R&S FSH.
For more information see "
Selecting the Unit of the Carrier Frequency Error

Concerning uncertainty of the reference frequency of the GPS receiver, refer to the
data sheet.
