MAXIMUM LEVELED OUTPUT POWER (Continued)
LEVELED OUTPUT POWER RANGE
Without an Attenuator:
Maximum leveled power to
–15 dBm (–20 dBm typical). For units with Option 15A
installed, minimum settable power is –5 dBm (–10 dBm
typical).
With an Attenuator:
Maximum leveled power to
–115 dBm (–120 dBm typical). For 68175B, 68177B,
68185B, 67187B, and units with Option 15A installed,
minimum settable power is –105 dBm (–110 dBm typical)
UNLEVELED OUTPUT POWER RANGE (typical)
Without an Attenuator:
>40 dB below max power.
With an Attenuator:
>130 dB below max power.
POWER LEVEL SWITCHING TIME (to within specified
accuracy):
Without Change in Step Attenuator:
<1ms typical
With Change in Step Attenuator:
<20 ms typical
