The NGJ-30 is a high-precision frequency standard using a rubidium oscillator.
It can be used not only as a frequency standard for communications and broadcasting networks, but also for a wide range of applications such as a high-precision frequency standard for use in factory and research facilities and for calibration of measuring instruments.

FEATURES

High stability and high precision

The frequency stability of < 5 x 10-11 / month is realized.

Multi-output terminal (built-in distributor)

A 7-output terminal is incorporated as standard, ensuring output distribution without any external distributor.

Automatic switchover of AC/DC power supply (with built-in backup battery)

AC/DC power supply can automatically be switched over, ensuring uninterrupted operation of the equipment in case of power failure. In addition, the built-in backup battery can supply a backup power until the generator is started.
