Abstract:
1. A method for use in an Arbitrary Waveform Generator (AWG) for synthesizing and generating an SSC modulated signal comprises the steps of: generating a modulating waveform with a frequency of an SSC modulation frequency; calculating the number of samples per data bit (SPUI) as a ratio of an upsampling frequency to data rate of a data stream; calculating an amplification factor as the ratio of SSC deviation frequency to data rate of the data stream; generating an array of SSC Edges containing an edge variation with respect to a single sample per bit, and multiplying the amplification factor to the modulating waveform; generating the array SSC Edges Upsampled, containing the edge variations with respect to an Upsample factor per bit, and multiplying SSC Edges with SPUI; calculating a resultant bit duration (SSC Bit Duration) as the sum of SSC Edges Upsampled and SPUI; calculating the successive summation of SSC Bit Duration, to get SSC Bit Position; storing the calculated results as a file in an AWG format in a memory of said AWG; reading said file and generating the SSC modulated waveform in response thereto; connecting an output terminal of said AWG to an input terminal of a device under test; and applying said generated SSC modulated signal to said input terminal of said device under test via said connection.
