Anritsu Corporation is launching the Rubidium™ family of signal generators, which boast superior usability and market leadership in signal purity and frequency stability.

Anritsu Corporation announced the introduction of the Rubidium™ family of signal generators delivering superior signal purity and frequency stability even at high output power levels over a wide frequency range of 9 kHz to 43.5 GHz.

Featuring easy-to-use, built-in frequency and power calibration capabilities, Rubidium™ delivers exceptional overall usability and long-term value across a wide range of commercial, military, and aerospace measurement applications.

Signal purity is critical to a wide range of measurement applications, from radar testing to ADC and DAC testing.

Rubidium™ signal generators deliver industry-leading low single sideband (SSB) phase noise of -136 dBc/Hz (typical) and -140 dBc/Hz (measured) at 10 GHz and 10 kHz offset.

Combined with best-in-class harmonic and spurious performance, Rubidium™ signal generators enable customers to make measurements with greater accuracy.

Rubidium™ provides better frequency stability compared to other signal generators using OCXO-based references.

This exceptional frequency stability is achieved by using the internal Rubidium™ reference option or by locking the signal generator's time base to the 1 PPS reference of the internal GNSS/GPS atomic clock receiver option.

The Rubidium™ signal generator is built-in, and frequency and level assurance can be easily performed in the field using touch-sensitive GUI buttons.

This feature ensures users can accurately determine levels and desired frequencies, saving time, improving convenience, and enhancing device availability. Field level calibration requires an Anritsu CW USB-powered sensor, while frequency calibration 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 enable a wide range of complex analog modulation signals. The internal low-frequency generator can generate seven different waveform types to modulate the carrier. Simultaneous AM/FM, AM/PM, or FM/pulse modulation can also generate complex modulation waveforms, such as chirps. For pulse radar testing, the signal generator features extensive signal simulation capabilities.

The Rubidium™ is housed in a 3U chassis with a 7-inch touchscreen on the front panel and a traditional keypad/dial interface. A variety of options are available to achieve optimal functionality, cost, and measurement flexibility.

Rubidium™ signal generators are suitable for a wide range of applications. They are ideal for applications requiring low phase noise, such as radar subsystems, up/down converters, or high-speed ADC/DAC testing. The signal generator is ideal for performing nonlinear measurements without additional filtering due to its extremely low harmonic, subharmonic, and anharmonic performance at standard and high output power levels. It can be used as a signal source for various interference measurements, test devices, and systems, and as a frequency reference in calibration and metrology laboratories.
