Spectrum Microwave’s line of Master reference oscillators (MROs) is vibration hardened ultra low noise Crystal oscillators intended for an airboe military application.
● SC cut crystal for stability and low noise.
● Ovenized oscillator has a less than 10-minute warm-up to achieve 0.5 PPM accuracy.
● Integrated doublers (x2 and x4), amplifier, built in power test, and band pass filter circuits.
● TTL oven ready indicator.
● Inteal voltage regulation to minimize pushing.
● Low resonance (<10 Hz) vibration isolation system to minimize the effects of vibration on phase noise performance.
