    • 1 The output power resulting from the gain setting varies over the frequency band and among devices.
    • 2 Frequency accuracy is based on temperature-compensated crystal oscillator (TCXO) vendor specifications and is not measured. Alternatively, you can incorporate an external reference source to provide a more precise frequency Reference Clock and to achieve better frequency accuracy.
    • 3 Instantaneous bandwidth depends on many factors including, but not limited to, network configuration and host computer performance. Actual data throughput may be chipset dependent.
    • 4 I/Q sample rate depends on many factors including, but not limited to, network configuration and host computer performance. Actual data throughput may be chipset dependent.
    • 5 The received signal amplitude resulting from the gain setting varies over the frequency band and among devices.
    • 6 Frequency accuracy is based on temperature-compensated crystal oscillator (TCXO) vendor specifications and is not measured. Alternatively, you can incorporate an external reference source to provide a more precise frequency Reference Clock and to achieve better frequency accuracy.
    • 7 Instantaneous bandwidth depends on many factors including, but not limited to, network configuration and host computer performance. Actual data throughput may be chipset dependent.
    • 8 I/Q sample rate depends on many factors including, but not limited to, network configuration and host computer performance. Actual data throughput may be chipset dependent.
