G3-135 • Low-frequency signal generator

The device is made in a 19-inch rack design with a 4U stand. The rubidium reference generator RRS-002 provides up to 15 independent signal outputs with a frequency of 10 MHz (5 MHz). The device is designed for long-term uninterrupted operation both in round-the-clock continuous and in session mode. The high reliability of the generator is ensured by reserving the main generator blocks and, in case of malfunction of the active signal source, automatically switching to a backup one.
