L5 system: 39A precision oscillator

The 39A precision oscillator is designed to operate at 40 watts from a 24-V ± 10-percent power source. The reference frequency can be set digitally to 5.12 MHz ± 5 × 10
⁻¹¹
over a tuning range of ± 4 × 10
⁻⁷
. The output signal is a 1-mW sinewave into a 100-ohm load. This performance is assured over a temperature range of 0 to 60 degrees Celsius. Oscillator outline dimensions for length, width, and height are 35.3, 22.1, and 21.8 cm respectively.
