GSM and EDGE Analyzer
Using the GSM Analyzer and the EDGE Analyzer
Option 230 - GSM Analyzer enables measurements of GSM signals. Similarly,
Option 235 - EDGE Analyzer enables measurements of EDGE signals.
This chapter explains how to make standard GSM measurements using Option 230 -
GSM Analyzer. It also explains how to make the more advanced EDGE
measurements for which you will require Option 235 - EDGE Analyzer.
GSM and EDGE transmitter measurements verify proper transmitter performance
and can be made with the base station in service or out of service. Important metrics
include:
• Frequency Error
• BSIC (Base Station Identification Code)
• TSC (Training Sequence Code)
• Modulation Type
• TS Pwr (Timeslot Power) in dBm
•TS Pwr in W
• Occupied Bandwidth
•I/Q Offset
• RMS Phase Error
• Peak Phase Error
• RMS EVM (Error Vector Magnitude)
• Peak EVM
• 95%tile EVM (95th Percentile EVM)
NOTE RMS EVM, Peak EVM, and 95%tile EVM measurements are only available if
Option 235 - EDGE Analyzer is installed
