Abstract

Procedures have been developed (Feb.1994) for enhancing the effective bandwidth of single-shot measurement systems. One procedure characterizes the transfer function of the measurement system hardware, and the other is a software compensation technique to deconvolve this transfer function from the acquired data. The example shown employs a Tektronix SCD-5000 Transient Digitizer, with a -3 dB bandwidth improvement of 4.5 times, to over 15 GHz.<>
