The Rubidium signal generator offers very low phase noise for single sideband (SSB) of -136 dBc/Hz (typical) and -140 dBc/Hz (measured) at 10 GHz with an offset of 10 kHz.
This frequency stability is achieved by means of an optional internal Rubidium reference or by setting the signal generator's time base to a 1 PPS reference from an optional internal GNSS/GPS atomic clock receiver.
The Rubidium signal generator incorporates field level and frequency calibration, accessible at the touch of a button on the graphical user interface. This feature guarantees the customer the accuracy of the desired frequency, saves time, increases convenience, and improves instrument availability.
An Anritsu USB CW power sensor is required for field level calibration, which also requires an internal GNSS/GPS atomic clock receiver or an optional, ultra-stable rubidium time base.
Rubidium's AM, FM/PM, and pulse modulation capabilities provide a wide variety of complex analog modulated signals. An internal low-frequency generator can produce seven different waveform types to modulate the carrier. Furthermore, simultaneous AM/FM, AM/PM, or FM/Pulse modulation allows for the generation of complex modulation waveforms known as "chirps." Powerful signal simulation capabilities are incorporated into the pulse radar signal generator.
The Rubidium has a 3U chassis with a 7-inch touchscreen on the front panel and a traditional keyboard or rotary dial interface. A wide range of options are available to achieve an optimal balance between cost/function and measurement flexibility.
