Measured and adjusted the RF power levels associated with the LO drive to the ASAIRA and ASAIRB demodulators (18, 45, 90 MHz) 45MHz to LSCAIR-A Changed pad at input to distribution amp to bring the RF drive level down by 3dB as measured at the demodulator end of the LO cable. The pad was 2 dB, now it is 5dB. The measured RF drive at the LO jack on the demodulator was 13.0dBm, and has now been reduced to 10.0dBm 18MHz to LSCAIR-B Added at 2dB pad to the RF distribution panel such that the measured LO at the demodulator LO input is now 10.0dBM 90MHz to LSCAIR-B Measured the LO drive at the demodulator LO input and found it to be 10.6dBm. Decided to leave it at that as it's close enough.
The signals from the RF patch panels to the distribution amplifier were also attenuated:
