configuration options of the wireless cable modems is to search the CATV frequency plan
looking for a valid downstream signal.
Figures 5-14 and 5-15 illustrate the effect of overdriving the Hub Transceiver. Both of these
traces were captured in the identical setup as Figure 5-13. The drive to the Hub Transmitter
was increased to create the distortion.

Figure 5-14: Example of slightly overdriven transmitter, at input to cable modem.
The wireless cable modem (WCM) may run with the signal shown in Figure 5-14, but the WCM
performance will be degraded. Note that the top of the signal is approximately 7 dB higher than
the desired signal shown in Figure 5-13.
