ISOTEMP RESEARCH, 434-295-3101, OCXO33 Series

OCXO 33 SERIES
	The OCXO33 series oscillators offer a wide variety of performance options for test and communications equipment . Single and dual oven designs are available to meet very tight temperature stabilities. Several choices of precision quartz resonators provide for low aging rates and low phase noise figures. Electrical trimming capability and heated voltage references make it ideal for GPS and Stratum 3E applications where disciplining is required.
