With all my recent measurements of CMCs, I've been encouraged by several
readers to put together a procedure for the various measurements I've made
with the HP 8753C, but using the NANOVNAs and SAVER. The attachment is the
first installment which presents a procedure using the NANOs and SAVER to
measure the DM loss through any CMC. It is also useful for measuring other
two-terminal transmissive devices such as filters, attenuators, active
stages, and.......

Have a look at my first cut. I'd invite anyone to make suggestions to make
things clearer and/or correct any errors I've made in the write-up. Have a
read of the attachment.

The next installment will address measuring the bulk CM impedance presented
by the CMCs using the NANOs and SAVER (another day, please) which have been
previously measured using the HP equipment.

Excellent Dave! Thank you for your many posts on this matter.

There should be a note in the beginning that the Nano itself
should be left in an uncalibrated state or calibrated for the desired
range.

Measure just the parallel line without the core to determine the loss of
the line?
