Internals
The 067-506 contains a feedback loop that maintains constant RF amplitude at the output connector regardless of small variations in load or internal variations, e.g., as the unit warms up. This is accomplished by using an envelope detector to measure the peak-to-peak output voltage, and using the envelope signal as feedback to set the plate voltage of the Colpitts RF oscillator, thereby controlling its swing.
Unlike later instruments like the 190 and SG504 that put the envelope detector in an output head, the 067-506 cannot compensate for variable losses in the output cable.
The +450 V power supply in the 067-506 is unregulated. The instrument relies on the RF feedback loop to maintain stability of the RF output voltage with respect to line voltage variation.
