This paper discusses the dynamic range of the SPARQ signal integrity network analyzer and considers the impact of several key specifications. It further compares dynamic range and key specifications of two competitive time-domain instruments and provides derivations and experimental results that support the calculations. SPARQ Dynamic Range TECHNICAL BRIEF Peter J. Pupalaikis VP & Principal Technologist Summary This paper discusses the dynamic range of the SPARQ signal integrity network analyzer and considers the impact of several key specifications. It further compares dynamic range and key specifications of two competitive time-domain instruments and provides derivations and experimental results that support the calculations. Dynamic Range The expression for dynamic range of any TDR based measurement instrument can be expressed according to the following equation which is derived in Appendix A - Derivation of Dynamic Range: Appendix A - Derivation of Dynamic Range: 2 A 2 f bw Fsact T S R( f , T )……
