Terminated (50Ω for single ended and 100Ω for differential) generator voltage
Output common mode voltage (DC average of V_OUT+ and V_OUT^−)
Variation in output common mode voltage (V_{O_CM})
Balance Error. Measure of the output swing balance of V_OUT+ and V_OUT^−, as reflected on the
output common mode voltage (V_{O_CM}), relative to the differential output swing (V_OUT). Calculated
as output common mode voltage change (ΔV_{O_CM}) divided into the output differential voltage
change (ΔV_OUT which is nominally around 800 mV_PP)
