3.10.4.2 Set the generator on the test set to -60dBm.
3.10.4.3 Check the Rx beam box and start the oscilloscope on PCCT.
3.10.4.4 Adjust the Rx Offset so the mean of the observed sine wave is centered as
close as possible about zero. Adjust the Rx Gain so that the signal peaks
are slightly less than +20000 and -20000 (See Figure 3-18).
