Agilent 16801A Manuals

[burnhamcontrol]

I am looking for info on a 16801A logic analyser, have found some manuals but could do with some circuit diagrams to use for fault finding. Anyone have anything that might be useful ?

I doubt you'll find any circuit diagrams. I think the last HP logic analyzers that had their schematics published came out in the 1980s (e.g. the 1630 series). You might be able to find block level diagrams, and otherwise search for troubleshooting reports on this forum and the HP_Agilent groups.io group. I'd expect the 16800 series acquisition boards to be fairly similar to the 16750 series of plug-in blades for the 16700 and 16900 series.

I'd expect the 16800 series acquisition boards to be fairly similar to the 16750 series of plug-in blades for the 16700 and 16900 series.

The 16803A, 16806A, and 16823A logic acquisition boards are essentially identical to 16910A 102 channel logic acquisition modules.

The 16802A, 16804A, and 16822A logic acquisition boards are essentially identical to 16911A 68 channel logic acquisition modules.

The 16801A and 16821A logic acquisition boards are essentially identical to 16912A 34 channel logic acquisition modules, but 16912A modules never existed as standalone products.

The 16821A, 16822A, and 16823A pattern generators boards are essentially identical to 16720A pattern generator modules.

As far as I know there must be some different values in the EEPROMs of these modules that lock them to use in 16800 series analyzers and normally prevent their use in 16900 series analyzers.

Anyway, if any self tests fail on the logic acquisition boards there probably isn't a lot that can be done to try to repair them, other than looking for corroded PCB traces that sometimes happens due to the corrosive adhesive issue on the skid runners on the bottom of the logic acquisition boards.
