At S9, the input signal level is 50µV (34 dBµ).
At S9 +20 dB, the input signal level is 54 dBµ.
• dBµ meter: Absolute voltage (Terminated)
0 dBµ is the level corresponding to 1 µV that is produced
on a 50 Ω terminated load.
• dBµ EMF meter: Absolute voltage (Opened)
EMF (Electro Motive Force) is the unit of voltage produced
at an opened terminal.
LIndicated in 6 dB higher than a 50 Ω terminated load.
• dBm meter: Absolute power
0 dBm is the level corresponding to 1 mW that is produced
