Tim, the Mini-circuits ZDC-20-3 covers 0.2 to 250 MHz. It is $45. Here is their ap note: www.minicircuits.com/appnote/coup7-2.pdf The Agilent 8721A covers 0.1 to 100 MHz. It runs $453. This one is better and covers the low end where I think you need coverage. Dave

ANSI C63.4 looks for the impedance curve (+/- 20% of reference) and the insertion loss (which should be a flat line, as close to zero as possible). I would need to get a bridge or some sort of adapter. Where would I get something like that. Thanks. Tim Pierce
