Pomona 4119-50 Bnc (M-F) Terminator Feed Through, 50 Ohm

This Pomona 50-ohm feed-through terminator might be expensive, but at least it works well. A screenshot of the S11 return loss as measured with my HP VNA is attached. For this test, the end of the terminator opposite the VNA was left open.Slightly annoying is that the part number is on a sticker that's already starting to peel off rather than engraved as shown in the listing photo. Minus one star for that; at this point, the marking should be at least laser-etched if not engraved.As with any feed-through terminator, no matter how good, don't expect similar performance when the male end is plugged into a 1 Mohm (nominal) scope input; the capacitance of the scope input starts to dominate above a few MHz or so.
