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 68075B, 68077B,
68085B, 68087B, 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

nomimal
Source SWR (Internal Leveling):
Without Attenuator: <1.7 at <2 GHz typical
<1.6 at 2 to 20 GHz typical
<2.0 at >20 GHz typical
With Attenuator: <2.0 typical
Power Level Stability with Temperature:
0.04 dB/°C typical
Level Offset: Offsets the displayed power level to establish
a new reference level.
OUTPUT ON/OFF: Toggles the RF output between an Off
and On state. During the Off state, the RF oscillator is turned
off. The On or Off state is indicated by two LEDs located
below the OUTPUT ON/OFF key on the front panel.
RF On/Off Between Frequency Steps: System menu se-
lection of RF On or RF Off during frequency switching in CW
or Step Sweep modes.
RF On/Off During Retrace: System menu selection of RF
On or RF Off during retrace.
