Single Channel 10 to 100 MHz Frequency Reference, OCXO Based

10 to 100 MHz Reference operates from -60 to +60 Vdc in Three Ranges or an AC adapter


The NR3700 10MHz frequency reference uses a low noise SC cut OCXO as the master timing source. The unit is offered at up to 100 MHz. The OCXO is biased with a band-gap reference to provide excellent temperature and and aging stability.  LED indicator provides self-test status. There is also a floating solid state relay that can be tied to an alarm panel self test status.

The NR3700 contains an optional factory configurable frequency synthesizer that operates from sub-1 Hz to 10 MHz.  The output is available on the SMA as a CMOS signal at 5 Vdc or 3.3 Vdc  CMOS capable of driving a 50 ohm load. An excellent simulated 1PPS source. The synthesized signal is also available as a LVDS or RS422.


The unit also has a LVDS, RS422 option.
