Hello,
Thank you for contacting Tektronix. The Y400 went out of long term product support in 2009. The Y400 was part of the Communication group here at Tektronix and that group went away in 2009. We no longer have anyone with experience on these items.
Support and parts are no longer available from Tektronix. Some customers have had success using one or more of these contacts for manuals:
