2. If you change the on/off setting of the level coupling, all ports
are automatically changed to the same level value as that of
port 1.
3. When setting level for all ports (Port Couple ON), click Power input
the power level using the ENTRY block keys on the front panel.
When setting level for each port (Port Couple OFF), click Port Power
and select the softkey corresponding to each port (Port 1 Power to Port 4
Power).
The table below describes the relation between source power level and
step attenuation:
Source Power Range Step Attenuation
-25 ~ +10 dBm 0 dB
-35 ~ 0 dBm 10 dB
-45 ~ -10 dBm 20 dB
-55 ~ -20 dBm 30 dB
-65 ~ -30 dBm 40 dB
-75 ~ -40 dBm 50 dB
-85 ~ -50 dBm 60 dB
For Auto Power Range setting, the minimum value of step attenuation is
selected according to the available source power level. The table below
describes the step attenuation selection based on the setting source
power level:
Source Power Range Step Attenuation
-25 ≤ power ≤ +10 dBm 0 dB
-35 ≤ power < -25 dBm 10 dB
-45 ≤ power < -35 dBm 20 dB
-55 ≤ power < -45 dBm 30 dB
-65 ≤ power < -55 dBm 40 dB
-75 ≤ power < -65 dBm 50 dB
-85 ≤ power < -75 dBm 60 dB
