Gentlemen,

?

If you can spare the time, calibrate your

nanoVNA boxes and run some profiles

on various coax jumpers.

?

Setting up the IRIG-B network at work required

any number of coax jumpers between various

panelboard instruments because everybody

in the band hadda be on the same beat.

?

So one day it all had to be proof-tested by

a third party, just like most of the other

control widgets, and this guy showed up

with a R&S VNA with a bag full of factory

jumpers, and the tech ran a Calibrate between

all tests, and we could plainly see that $50

jumpers were nowhere near one another

on the curve screen.

?

So yes, using a longer chunka coax does make

a difference, especially if it’s premium flavor.
