I don't suppose anyone knows of a source of schematics/CLIP information for this series of SA or is it just too modern?
?
Having repaired the PSU, I've got a number of calibration errors which suggest to me possibly an issue with an LO other than 1st LO (possibly the 2nd LO).? The only schematic the service manual deigns to include is the backplane which was helpful for fixing the PSU.
?
I like the fact that CAD meant including diagrams in manuals was harder than when they were drawn by hand!? But as a one time resident of Hanover Street, Palo Alto, it is amusing to see the 3000 Hanover Street address pop up on startup.? In many ways this seems to have similarities with the 16700 LA mainframe.
?
I'll take it to visit a trusty HP141 + 8555 to see if the 2nd LO is working properly as at 3.6GHz.
