• Required Mask Delta - Sets the value (between -10 db and 10 dB) that is considered to be
absolutely required. If this level is exceeded, the digital power from the transmitter will be
reduced if the PA voltage is at maximum. If the spectral mask still cannot be met and the set-
ting for it is enabled, the transmitter power set-point will be reduced.
• Reduce Digital Power If Required: Select Yes or No. Selecting Yes enables a reduction in
injection level (digital power) if the spectrum mask requires it.
• Reduce Power Set-Point If Required: Select Yes or No. Selecting Yes enables a reduction in
the transmitter power set-point if the sepctrum mask requires it.
