This mode of operation requires a feedback connection from a
negative-output diode detector to the EXT ALC connector.

Normal, Power Meter (PwrMtr),
In
controls the output power of the synthesizer as compared to the
feedback voltage of the power meter. The attenuator (if present) is
automatically uncoupled from the ALC system and the
key controls the Level DAC and Level Control Circuits (see
Figure A-l) within a more restricted range of the ALC level.
Instead of the 45 dB range of the ALC in other modes, 12 dB is
available in this mode, with the upper end of the range set by the
Pwr Mtr Range softkey. This mode of operation requires a feedback
connection from the recorder output of a power meter.
