Product Comparision


 

Oscillators & Hold Over Mode

The main difference between products: NTS-3000, NTS-4000, NTS-5000 is stability of oscillators they use when operating GPS-less mode - the holdover mode (HO). The NTS-3000 is requiring near continuous GPS synchronization. It is because NTS-3000 does not include single internal hardware oscillator (OSC: TCXO, OCXO, RUBIDIUM). The GPS less time keeping of NTS-3000 basis on software PLL/FLL implementatin. This is suitable assuming there are no frequent and very short breaks in receiving GPS signals.  The NTS-4000 OCXO can work many days, or ewen weeks without receiving GPS signals. It is powered by OCXO oscillator that has very good short term stability. The NTS-5000 RUBIDIUM is best one. It is actually requiring only periodic synchronization to GPS - once (a couple of hours only) per many months GPS less operation.
