In externally leveled operations, the output power from the swept
CW generator is detected by an external sensor. The output of this
detector is returned to the leveling circuitry, and the output power

is automatically adjusted to keep power constant at the point of

detection.

Leveling with

Figure l-11 illustrates a typical setup for external leveling. When

Detectors/Couplers

externally leveled, the power level feedback is taken from the external

/Splitters

negative detector input rather than the internal detector. This
feedback voltage controls the ALC system to set the desired RF
output. Refer to Figure A-l in Chapter 2 for a block diagram of the
swept CW generator’s ALC circuitry.
