Gents, I have a 3458A on its way to me that fails self test with the error "202 Hardware Failure - Slave Test: AC Board". The assembly-level repair manual calls for replacing the AC converter board (at $1200 minus a $200 trade-in for the broken board). Assuming that it is actually broken and its not something simple, does any one have an opinion on the repairability of the board? Would the component-level "information packet" be worthwhile? Or, should I just bite the bullet and buy a new board from Agilent? Thanks. Randy. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
