RF spectrální grafy s vysokým rozlišením
AirMedic USB provides visibility into the physical layer of the WLAN, to identify RF interference and problems in the environment that directly impact the performance of the network. Key RF spectrum graphs include:
- Real-Time FFT - provides a real-time view into the RF energy in the environment with current, max, max hold and average RF signal levels.
- Spectrum Density - provides a longer-term view into the network by displaying live information on the signals that have been common during the current capture session. This can be very helpful to identify infrequent transmitters.
- Spectrogram - provides a scrolling history of the RF environment and allows a visual understanding of the spectrum over time to see intermittent spikes or bursts of RF energy that may be causing WLAN network problems.
- Duty Cycle - tells you just how often an interfering signal is present. A high duty cycle means an interferer is constantly transmitting and will most certainly cause problems on the affected channel.
- Channel Power - shows the maximum and average power levels across all the channels in the selected radio band.
- Channel Duty Cycle vs. Time Trending - shows the average power in the channels that is above the noise floor over a specific period of time.
