Description
CTS Model 144 uses the internal heating resonator (IHR) technology with arrangement of the whole oven control
system together with the crystal plate inside the T08 vacuum holder to radically reduce the OCXO size, power
consumption, and 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.
