More information

Anritsu Rubidium MG36221A offers atomic clock frequency stability with an internal rubidium frequency reference option. Alternatively, customers can also get exceptional frequency stability by locking an internal oven controlled crystal oscillator (OCXO) reference to an external GNSS/GPS signal. The exceptional frequency stability makes Rubidium an ideal signal generator for Metrology and high speed clock applications.

 

Signal purity and frequency stability are essential distinguishing characteristics of a high frequency microwave signal generator. The Rubidium MG36221A signal generator product line is built to deliver outstanding signal purity and frequency stability across a broad frequency range of 9 kHz to 20 GHz, even at high output power levels. Coupled with built-in, easy-to-use, at location frequency and power calibration capability, the low noise RF/microwave signal generator Rubidium MG36221A offers exceptional overall utility and long term value for a broad range of measurement applications.

 

The Rubidium MG36221A standard phase noise outperforms competition by a substantial margin. Two additional tiers of phase noise performance on top of the standard phase noise performance are offered as options. The low phase noise option delivers improved close in phase noise along with better frequency stability. The ultra low phase noise option provides improved phase noise at higher offsets. For CW only applications between 2 GHz to 20 GHz, Rubidium provides an even lower phase noise than the ultra low phase noise option, allowing for another 3 dB improvement on a separate RF output port at the back panel.

 

The low noise RF/microwave signal generator Rubidium MG36221A offers atomic clock frequency stability with an internal rubidium frequency reference option. Alternatively, customers can get exceptional frequency stability by locking an internal oven controlled crystal (OCXO) reference to an external GNSS signal. The exceptional frequency stability coupled with low phase noise performance makes the Rubidium MG36221A the ideal choice for many measurement applications.

 

The Rubidium MG36221A modulation capabilities include amplitude, frequency, phase, and pulse modulation to address simple to complex signal simulation requirements. It offers very comprehensive pulse generation capabilities to test pulsed radar systems. It also supports Anritsu’s True-RMS and CW power sensors.

 

The Rubidium MG36221A is housed in a 3U chassis with a 7-inch touch screen on the front panel and traditional keypad/dial interface. The Rubidium MG36221A offers a high degree of configurability through a wide range of options to achieve optimum cost to function tradeoffs for the customers.
