For repairing a generator to 18GHz from which the attenuator was removed I need to find a replacement. I believe any of these would work (with SMA inputs/outputs) but am more than happy to do some rewiring

Current Keysight part seems to be 8496H. Given that this is for a repair for a piece of equipment for home use, Keysight prices are too steep so I'm probably realistically looking for one in need of some repair. The manual seems to suggest that it's worth holding a spare one in your "stores" so I guess there were issues with them!
