Agilent Technologies e4418b, e4419b Power Reference Oscillator Frequency Adjustment, Description

	Adjustments
	Power Reference Oscillator Frequency Adjustment
	Power Reference Oscillator Frequency Adjustment
Note	Adjustment of the power reference oscillator frequency may also
	affect the output level of the oscillator. Therefore, after the
	frequency is adjusted to 50.0 ±0.5 MHz, the output level should be
	checked as described in “Power Reference Oscillator Level
	Adjustment”, on page 3-6.
	The power reference oscillator frequency is a nominal
	specification.
	Description
	Variable inductor A2L9 is adjusted to set the power reference oscillator
	output frequency to 50.0 ±0.5 MHz. This frequency is a supplemental
	characteristic.
