Hi Paul,

I don't know how good Pasternack are - I have seen some rather dubious
connectors from them. But I did contact their UK agents yesterday and asked
for a quote.

I found another company on the web, that does connectors as small as 1.0
mm. The fact that they do such connectors gives me a bit of confidence they
know what they are doing.

Since I will need to bend some cables, I might try to beg, borrow or steal
a 2.4 mm connector gage.

I have seen so many new items with out of spec connectors, I have a healthy
skepticism of connectors, and any keen not to connect a dodgy connector to
expensive items. One of my ex employers would send out dodgy connectors,
in the expectation a customer would not check them.

I am pretty sure that adding these cables will degrade the dynamic range a
little, although the specs of the instrument with & without direct sampler
access are the same. On the 40 GHz version of this instrument,  I think the
specification is degraded a bit.

So I am keen for the cables to be as good as possible.

At least I know I could have trusted the cables from Agilent   - I am less
convinced about Pasternack.

I am kicking myself as 3 of the four 2.4 mm cables were available from
Agilent a year ago. Now they are all sold. They would have been preferable
as they would have the necessary bends in place.
