Apologies for the stupid question, but...
I am using an 8753ES with an 85046A S Parameter Test Set. After calibration using Full 2-Port, and using a 50 ohm coaxial air line as a DUT, the instrument is reading out S Parameters with units such as 850 mV for S21. I don't understand the units; shouldn't these parameters be dimensionless? I would have expected to see the values expressed as some percentage of the generator power. What am I missing? The calculated Transmission coefficient is larger than unity, which suggests I am missing normalization somewhere.
Again, apologies for the stupid question, but I'm not finding any answers in the manual or searching this forum.

What's your format? Put it in LogMag and the values will be in dB, which is a relative measurement. To my knowledge, the units cannot be mV in the '53. is it really saying mU (as in milli-units?). This is the linear value where a unit is dimensionless (just like dB).
