Mike,
Some attenuators are based on a ferrite element that provides relatively constant loss at high frequencies but less loss at low frequencies, I have seen such attenuators with N connectors, but don't recall any with SMA connectors.

Hi All,
New to the group. I have a SAA-2N w/N connectors and cal set. With the
necessary adapters (SMA to N etc..) I am not sure I understand if my
measurements are correct. Measured (stimulus) from 1MHz - 100MHz;
calibrated w/cal set. I then connected a 30db attn and it reads -25.6db
@ 30MHz, what is going on? Note: this attn is marked 7-16.5GHz and is an
SMA. (I have many of these attenuators and several tests on various
units produces nearly the same results)
