RSL Test Point. At nominally -26 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 -29 dBm, the attenuator is disengaged, and the meter will reflect the
unattenuated value. See Figure 9-4.
Note: To prevent damage to
the connectors, do not
exceed 8 to 9 in-pounds of
torque.
