Maximize Speed and Rack Space with the Pure and Precise MXG

With increased vigilance on program efficiencies placing constraints on budget and space, the MXG microwave analog signal generator offers an alternative in size, speed, and cost. Crafted to create signals capable of testing your most advanced systems or components, these signal generators offer industry-leading performance and low cost of ownership.

Pure and precise, the N5183B MXG delivers the performance you need for spectral purity, output power, and more—to perform module- and system-level testing. The MXG microwave allows you to address demanding tests of radar modules and systems offering best-in-class phase noise and switching speed of less than 600 μs.

Enhanced Phase Noise with Triple-loop Synthesis

The MXG implements a new tripleloop phased-lock loop (PLL) design and frequency plan that results in substantial phase noise improvements close to the carrier and at wide offsets. The frequency plan addresses several key attributes: the choice of oscillator and reference frequencies in the synthesizer and the associated frequency conversion (mixers and multipliers) and filtering.

The triple-loop approach allows optimized frequency spacing that ensures effective filtering of nonlinear artifacts, such as images, by pushing them outside the bandwidth of the synthesizer circuits. In the MXG, the plan arranges the frequency references and conversions such that the largest nonlinearities are far from the desired frequencies and modest filtering can heavily attenuate the remaining spurious signals.
