Description
The Model 148 is a high stability, low power OCXO that utilizes an SC-cut quartz resonator. The SC resonator insures
excellent phase noise and low aging rates. The novel design featuring the oscillator and oven control circuitry inside of the
vacuum-sealed TO-8 crystal enclosure provides reduced size, fast warm-up, and excellent temperature stability. In addition
to improved performance characteristics, the compact design of Model 148 offers increased resilience to mechanical shock
and vibration.
