I can't order 16340A CR BOX which is necessary for the performance test of 4339B and 4349B. How can I get 16340A?
16340A was obsolete on Aug 1, 2003. The replacement CR box is the combination of 16353A, 16353H and 42038A. For the performance test procedure and adjustment procedure with using 16343A/H and 42038A, see the following documents.
