DUT Type Loss Compensation

For all of the DUT Types (Amplifier, Downconverter, Upconverter, and
Multi-Stage Converter) the loss compensation, before the DUT (BeforeDUT)
and after the DUT (AfterDUT) can be enabled or disabled for loss and for
temperature.
Loss compensation can be used to compensate for double sidebands (DSB).
Loss compensation can be used in the case of DSB measurements to
compensate for the doubling of the measured noise level (i.e., 3.01 dB
increase). For all sideband cases you can enable or disable Loss (device loss)
and Temperature (device temperature). Refer to Figure 30-9 on page 675.
