MSG Series

Synthesizer

Noise XT and Phase Matrix collaboration enabled the generation of a high performance, affordable Microwave Signal Generator . The MSG series exhibits outstanding phase noise in a compact instrument. The QuickSyn® engine employs a patented, revolutionary phase-refining technology that provides a unique combination of fast-switching speed and low phase-noise characteristics.

Models MSG-10-1/2 and MSG-20-1/2 cover the frequency ranges of 0.5 to 10 GHz and 0.5 to 20 GHz respectively (extendable down to 0.1 GHz and 0.2 GHz). MSG synthesizers utilize a fundamental VCO to achieve the desired output frequency.

In contrast to frequency multiplication schemes, this approach eliminates possible spectrum contamination from sub-harmonic products. The use of the advanced direct digital synthesis approach, enables a very fine frequency resolution of 0.001 Hz.

The VCO noise is suppressed by utilizing an ultra low noise reference oscillator in conjunction with a low-noise locking mechanism. Microphonic effects are also greatly reduced due to the use of a low-mass VCO and very wide PLL filter bandwidth.

Note:

      1. Frequency extension down to 0.1 GHz (MSG-10) and 0.2 GHz (MSG-20) are available as option 1. Output power between 0.1 and 0.5 GHz is limited at +10 dBm. Harmonics may increase below 0.5 GHz.
      2. Available with option 2 only. Power accuracy may change at low power levels.
      3. Measured at maximum specified power.
      4. Measured with power set at mid range. AM is clipped when available power (min. or max.) is reached.
      5. AM and FM sensitivity is dependent on synthesizer output frequency and is controllable by software.
      6. The amplitude of the FM input signal must be adjusted to obtain the desired deviation according to the output frequency range.
      7. External reference frequency input to be within ± 2 ppm max.
