Power Reference Oscillator Frequency Adjustment
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.
Equipment
• Frequency Counter: Agilent 53132A.
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,
check the output level should be checked as described in “Power Reference Oscillator
Level Adjustment” on page 65. The power reference oscillator frequency is a nominal
specification.
