￿ Gain dB: Gain (or S21) is measured at each CW tone as the power is swept The measure- ment is made in IMD mode. The Gain is actu- ally measured by calculating the difference be- tween Power In (in dBm) and Power Out (in dBm). Calibration applied is Linear Power Cal and Receiver Cal. (Could also be called Gain and compression measurement). The displayed Power In level is the power of each input tone.

￿ Gain dB: See above.
