Anritsu has introduced the Rubidium signal generator family that delivers outstanding signal purity and frequency stability, across a broad frequency range of 9 kHz to 43.5 GHz.
The Rubidium signal generator offers groundbreaking low single sideband (SSB) phase noise of -136 dBc/Hz (typical) and -140 dBc/Hz (measured) at 10 GHz and 10 kHz offset – enabling customers to make measurements with better accuracy.
The test and measurement company said Rubidium signal generator offers exceptional frequency stability by achieving either by an optional internal Rubidium reference or by locking the signal generator’s time base to a 1 PPS reference from an optional internal GNSS/GPS atomic clock receiver.
The Rubidium signal generator features on-site frequency, and level calibration that is easily accessible with the touch of a button on the GUI interface. This feature ensures customer level, accurate frequency desired, timesaving, enhancing convenience, and increasing instrument availability.
An Anritsu CW USB power sensor is required for onsite level calibration. An internal GNSS/GPS atomic clock receiver or ultra-stability rubidium time base option is required for onsite frequency calibration.
Rubidium’s AM, FM/PM, and pulse modulation capabilities enable a wide range of complex analog modulated signals. An internal low frequency generator can produce seven waveform types to modulate the carrier.
Simultaneous modulation of AM/FM, AM/PM, or FM/Pulse is possible to generate complex modulation waveforms such as chirps. Broad signal simulation capabilities are built into the signal generator for pulsed radar testing.
Anritsu said the signal generator is housed in a 3U chassis with a 7-inch touch screen on the front panel with a traditional keypad/dial interface. A wide range of options are offered to achieve optimum cost-to-function and measurement flexibility.
Rubidium can be used in multiple applications. It is ideal for low phase noise applications, such as testing radar subsystems, up/down converters, or high-speed ADCs/DACs. The signal generator is well suited for conducting nonlinear measurements without additional filters.
