Hi All
Recently I repaired for a friend his E4406A where a switch was defective
and where the original switch 1GG7-4218 was no longer available.
An alternative switch Hewlett Packard MGS-71018 could be acquired from
RF-Microwave (link in the document attached).
However, the original switch had control voltage as + - 5V but the
substitute 0 and -5V and the two control pin swapped, so a modification
needed.
I did a detailed document how this modification is made.
Kind regards
Kurt
