How do I measure the loss on one port of a four way 0 degree 50 ohm power splitter? Do I have to terminate the other ports? Or should I leave the other ports w/ no connection?
I'm talking of a 3 dB attenuator. Isn't the 3 dB attenuation increase to 6 dB because of the presence of the resistor to ground? Is there a way to compute this?
Imagine this circuit, a source in series w/ a 3db pad (50 ohm) connected to a resistor (50ohm) via ground. Will the attenuation be 3 dB? How will I compute for the attenuation taking account the 50 ohm resistor?
