Page 14: About The Measurement
® About the Measurement R&S FSW-K10 3 About the Measurement A basic GSM measurement in the R&S FSW GSM application includes a power vs time and a spectrum measurement, as well as modulation accuracy (e.g. EVM, phase error) for a GSM signal as defined by the relevant 3GPP standards. The I/Q data from the GSM signal applied to the RF input of the R&S FSW is captured for a specified measurement time. -

® Measurements and Result Displays R&S FSW-K10 GSM I/Q Measurement Results 4 Measurements and Result Displays The R&S FSW GSM application provides two different measurements in order to deter- mine the parameters described by the GSM specifications. The default GSM I/Q measurement captures the I/Q data from the GSM signal. The I/Q data includes magnitude and phase information, which allows the R&S FSW GSM application to demodulate signals and determine various characteristic signal parame- ters such as the modulation accuracy, power vs time, modulation and transient spec-... - Page 16 ® Measurements and Result Displays R&S FSW-K10 GSM I/Q Measurement Results The following evaluation methods are available for GSM I/Q measurements: Constellation......................... 16 EVM..........................16 Magnitude Capture......................17 Magnitude Error......................18 Marker Table ........................ 18 Modulation Accuracy.....................19 Modulation Spectrum Graph..................21 Modulation Spectrum Table...................22 Phase...
