      • The maximum EIRP is
        • 33 dBm/10 MHz in CBSD-B mode
        • 30 dBm/10 Mhz in CBSD-A mode
        • This number is ignored in EUD mode
      • Low Frequency and High Frequency are user limits for the requested frequency of operation (provided by the SAS)
      • The Operating Mode should be set to CBSD-B for the purposes of this guide.
