WLAN Measurement Suite
complete suite measurement functions analyze IEEE802.11 WLAN transmitter performance conjunction with 3030 series digitizers.
Transmit power Transmit burst length Transmit power timing Spectral mask Occupied bandwidth Frequency tolerance Symbol chip clock frequency tolerance Carrier suppression/leakage Modulation accuracy (EVM) Spectral flatness with 3030 series digitizer transmission parameters using digital data derived from digitizer. This makes ideal conjunction with Aeroflex 3030 series digitizers enables precision characterization alignment WLAN transmitters. Applications WLAN measurement suite designed based test systems used development manufacturing. complemented IQCreator, waveform creation application software generating complex modulation including IEEE 802.11a, signals compatible with 3020 series digital signal generator modules. Highlights WLAN measurement suite provides analysis major transmit signal characteristics defined IEEE 802.11a,b 1999 IEEE 802.11g 2003. Automatic setting modulation format. Data rates corresponding modulation encoding formats Mb/s supported. Modulation format selection automated, data rate modulation type determined directly from preamble header decoding. preamble type also automatically determined making using measurement library easy integrate within test application. Most measurement parameters calculated from single acquired data. Spectral mask Adjacent channel power measurements combine data from multiple acquisitions different frequencies. number acquisitions necessary function

required measurement span digitizer bandwidth. Individual measurement groups calculated isolation which case measurement time accelerated single measurement type. Measurement Speed Complete WLAN analysis achieved Typical measurement times (ms) different test conditions shown table above. These measurements were performed using Pentium embedded controller measure OFDM PPDU with 1024 octets DSSS PPDU with octets acquired with sampling rate 30.72 Ms/s digitizer bandwidth MHz. Higher speed measurement possible when using wider bandwidth digitizer 3030A/3035 higher speed controller. Measurements based upon general assumption that device under test commanded transmit bursts. Analysis performed continuous transmission with addition pointer start preamble input data. Example Code measurement suite supplied with comprehensive help including useful example source code user development measurement applications. Examples supplied variety applications development environments including Visual Basic (VB6) C/C++.
