Center Frequency Output Power RF Output Average Noise Density
50 MHz to 7.5 GHz -30 dBm -166
>7.5 GHz to 8.5 GHz -30 dBm -165
50 MHz to 3.0 GHz 0 dBm -151
>3.0 GHz to 7.5 GHz 0 dBm -150
>7.5 GHz to 8.5 GHz 0 dBm -146
50 MHz to 2.0 GHz 20 dBm -132
>2.0 GHz to 5.0 GHz 18 dBm -133
>5.0 GHz to 7.0 GHz 17 dBm -134
>7.0 GHz to 8.5 GHz 15 dBm -130
Conditions:
  • Measurement configuration: power measured at the center frequency; 10 averages; normalized to a 1 Hz equivalent noise bandwidth.
  • Generation configuration: -40 dBr CW signal 5 MHz offset from the measurement frequency.
  • Noise for power level setting of -30 dBm is limited by the measurement instrument.

Noise relative to output power, in dBc/Hz, is the difference between noise power density, in dBm/Hz, and the output power level in dBm.
