The SM6218 from Kratos is a fast, broadband, indirect synthesizer with a modulation function. It can generate a frequency from 2 to 18 GHz. The modulation function makes the synthesizer well suited for use in various test systems where the signal output of the signal generator needs to be modulated rather than be just a CW signal. It offers a higher performance and cost effective alternative to signal generators currently used in various applications such as Test Systems and especially those which require improved frequency accuracy, phase noise and frequency modulation capabilities.
