I agree with you John, in that Joel is very helpful. This help not
only extends to someone owning the latest and greatest VNAs, but
people like myself who own obsolete HP kit. His suggest to repair the
thread, rather than pay a fortune to get the whole coupler replaced,
saved me a lot of money.
The US dealer I purchased this from offered to get it repaired, but
that repair was changing the test port, not the whole coupler. I had
concerns about that, as the tollerence in replacing just the test port
is very stringent. IIRC, it has to be aligned to 0.0001". I would not
trust anyone other than Agilent to do that job.
Anyway, the VNA appears to work well now. I've been making measurement
with it this morning - one way to spend Christmas day!!
