20dB Bandwidth
Connect the antenna port(s) to the spectrum analyzer input. Using the spectrum analyzer Channel Bandwidth mode,
configure the spectrum analyzer as shown below (enter all losses between the transmitter output and the spectrum
analyzer).
        Center Frequency:      Frequency from table be.low
        Span:                  2 x Nominal Bandwidth (e.g. 40MHz for a 20MHz channel)
        Reference Level:      20 dBm
        Attenuation:          10 dB
        Sweep Time:            5s
        Resolution Bandwidth:    1%-3% of 20 dB Bandwidth
        Video Bandwidth: ≥Resolution Bandwidth
        X dB Bandwidth: 20 dB
        Detector:              Peak
        Trace:                Single
 Place the radio in continuous transmit mode. View the transmitter waveform on the spectrum analyzer, and record the
pertinent measurements:
