MAXIMUM LEVELED OUTPUT POWER
LEVELED OUTPUT POWER RANGE
Without an Attenuator: Maximum leveled power to
–15 dBm (–20 dBm typical). For units with Option 15 in-
stalled, minimum settable power is –5 dBm (–10 dBm
typical).
With an Attenuator:
Maximum leveled power to
–125 dBm (–130 dBm typical). For units with Option 15
instal led, mi ni mum settable power is –115 dBm
(–120 dBm typical)
UNLEVELED OUTPUT POWER RANGE (typical)
Without an Attenuator: 40 dB below max power.
With an Attenuator: 150 dB below max power.
