7.4.6 PSD Setting
Figure 58 PSD Setting Screen
The PSD (Power Spectral Density) setting screen provides a place for the end user to
adjust power levels for each Powerline subcarrier. The factory default is 128. Each
subcarrier can be raised or lowered in small steps from 255 down to a value of 0, which
will turn it off.
At a PSD value of 128, the power output of the device is about 22dBm, or -50dBm/Hz.
Lowering the values of the PSD setting will lower the power output of the gateway and/or
modem and correspondingly will decrease the distance at which the devices will be able
to communicate. Raising the PSD value increases power output, but if it is raised above
approximately 169, noise will start to degrade the signal.
Refer to PSD information for the Gateway, in Section 6.5.3.
The PSD web page is designed to allow the system operator to respond quickly to any
radio frequency complaint and adjust Powerline carriers accordingly.
Grayed out values are reserved HAM radio frequencies and cannot be adjusted.
