Also note that changing the RF attenuator on the output of the RFP module will affect the baseband drive voltage level necessary to produce the required klystron drive power. Lowering the value of the attenuator also lowers the baseband voltage but raises the saturated drive power, so there is a trade off. Ideally the range of gain adjustment (20*log10(Maximum/Minimum)) should provide sufficient range to cover the no beam klystron power to 90% of the full rated klystron power (to allow for modulation headroom). Clearly the LER is the more difficult case since the no beam power is half that of a HER station. Normally HER = 0.600 volts, LER = 0.500 volts.
