Group Delay Measurements of Converters with Inaccessible Local Oscillators J. Martens and P. Kapetanic Anritsu Company, 490 Jarvis Drive, Morgan Hill, CA 95123 USA jmartens-anritsu.com ABSTRACT With the rapidly increasing demands on converter performance under modulated conditions, one measurement that has become more common is that of group delay flatness. For cost and other reasons, the local o
