  1. Wireless LANEmissions Investigation • 2 Devices Provided For Evaluation • Breezenet AP-10 • Twin Antenna Frequency Hopper • Nokia A032 • Single Antenna SinX/X

  2. Test Methodologies Used • Conducted Emissions (Breezenet One Antenna) • Swept Receiver • 12 Samples (Sweeps) • Stepped Receiver • 1MHz Steps • Radiated Emissions • Mode Tuned (MT) • 12 Samples Swept Receiver • Mode Stirred (MS) • Continuous Tuner Rotation (Rate Matched Sweep Time) • Fast Mode Stirred (FMS) • 2 Sec. Tuner Rotation Varying Sweep Times • Frequency Stepped (FS) • 7.5 Sec. Tuner Rotation Rate • Stepped Receiver 1 MHz Increments

  3. Receiver Settings • Receiver HP8564E Spectrum Analyzer • Freq. Span 2365 MHz to 2515 MHz (601pts) • Sweep Times 7.5, 15, 30, 60 & 120 Sec. • RBW 1 MHz & 10 kHz • VBW 3 MHz • Max Hold Used

  4. Breezenet AP-10 • Conducted Emissions • Single Antenna Port via K Connector • Receiver Swept Measurements • 5 Receiver Sweep Times (7.5, 15, 30, 60, 120 Sec.) • 2 RBW Settings For Each (1MHz and 10KHz) • 12 Sweeps Each Setting Max Hold On • Receiver Stepped Measurements • 1 MHz Frequency Steps • 1 MHz RBW, 3 MHz VBW • Receiver Sweep Time of 50mS • Max Hold for 60 Seconds (1200 Sweeps)

  5. Breezenet AP-10Radiated Emissions • MODE TUNED • Receiver Swept Measurements • 5 Receiver Sweep Times (7.5, 15, 30, 60, 120 Sec.) • 2 RBW Settings For Each (1MHz and 10KHz) • 12 Sweeps Each Setting Max Hold On

  6. Breezenet AP-10Radiated Emissions • MATCHED (SYNCED) MODE STIRRED • Receiver Swept Measurements • 5 Receiver Sweep Times (7.5, 15, 30, 60, 120 Sec.) • 2 RBW Settings For Each (1MHz and 10KHz) • Tuner Rotation Matched Sweep Time (12 Samples)

  7. Breezenet AP-10Radiated Emissions • FAST MODE STIRRED • Receiver Swept Measurements • 5 Receiver Sweep Times (7.5, 15, 30, 60, 120 Sec.) • 1MHz RBW • Tuner Rotation 2 Seconds • Receiver Sweep Time of 50mS • Max Hold for 60 Seconds (1200 Sweeps)

  8. Breezenet AP-10Radiated Emissions • FREQUENCY STEPPED • Receiver Stepped Measurements • 1 MHz Frequency Steps • 1 MHz RBW, 3 MHz VBW • Receiver Sweep Time of 50mS • Max Hold for 60 Seconds (1200 Sweeps)
