As the 86260A does not have internal leveling option fitted, the External Input is used to provide a dc input from a Crystal Detector or Power Meter. These provide a power leveling source via a power splitter or directional coupler from the RF Output.
The FM input can also be used for a phase-lock signal (PL position of switch). The Sweep Ref is a frequency reference voltage output. A Rear Panel RF Output can be provided with Option 004. Amplitude Modulation is available from the 8620C at 1kHz or via an external signal.
