Hello Technetters,

We are a small shop building primarily prototype quickturn commercial
and military medium technology product.

We use an impedance calculator from Polar and a tdr to verify impedance
on coupons from the same panel.  The coupons reflected the impedance
design with a 7 inch trace.  This has worked will for us.

Now we are at a point where we need to repair the tdr or move toward
another system of testing.
I've thought about Polar's CITS and the system from Introbotics...

The question...

What experiences has anyone had with the CITS and/or Introbotics versus
using a tdr?
What other methods are out there for verifying impedance on a printed
circuit board (bare board) in a manufacturing environment?

Any input is appreciated,

Thank you and have a Great Holiday!
