Description
The
Model 144
uses the internal heating resonator (IHR) technology with arrangement of the whole oven control
system together with the crystal plate inside the TO-8 vacuum holder to radically reduce the OCXO size, power
consumption, and its warm-up time. In addition, the
Model 144
offers excellent temperature stability, low phase-
noise and aging rate despite its miniature size and extremely low power consumption. The oscillator has the
performance of high-end OCXOs which use conventional oven designs.
