R&S FSH Digital Modulation Analyzer
Measurements on 1xEV-DO Signals
Operating Manual 1173.6275.12 - 30 287
Trigger
Shows the current trigger mode.
For more information see "Working with Trigger Functionality" on page 106.
In addition to the trigger also available with the base unit, the application also feature a
GPS Sync trigger. It triggers measurements on synchronization with the base station.
9.6.1.2 Global Results
Global results contain various measurement results of the composite signal. These
results evaluate the total signal over the period of one frame. Global results also
contain information about the queliaty of the composite signal.
Channel Power
Total power of the signal in dBm in the 1.23 MHz bandwidth around the center
frequency.
Carrier Frequency 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
291.
Concerning uncertainty of the reference frequency of the GPS receiver, refer to the
data sheet.
Peak to Average
Shows the difference between the peak power and the average power of the signal
(crest factor).
PN Found
The PN offset found during auto PN offset operation.
Tau
Tau is specified in the CDMA2000 standard. It shows the timing error of the signal. The
maximum offset is specified at 10 µs.
Traffic Activity
Percentage of traffic slots with data.
