Figure 8-3: Receiver Assembly, front view
RSL Test Point
At -21 dBm or higher, a 10 dB attenuator is engaged, resulting in a 1 volt drop
(apparent 10 dB) in the RSL test point reading. The Keypad will display the
corrected (unattenuated) value. At nominally -23 dBm, the attenuator is
disengaged, and the meter will reflect the unattenuated value. See Figure 8-4.
Note: To prevent damage to
the connectors, do not
exceed 8 to 9 in-pounds of
torque.
