1. Source attenuator for E8362/3 /4B is 60 dB in 10 dB steps. Source attenuator for E8361A
is 50 dB in 10 dB steps.
2. Receiver attenuator for E8362/3 /4B is 35 dB in 5 dB steps. Receiver attenuator for
E8361A is 50 dB in 10 dB steps.
Power levels shown on the diagram are damage levels. At a minimum, keep power levels 6 dB below damage level. For
optimal performance, keep the power level incident upon the receivers –20 dBm or less. This will keep the receivers out of
compression.
