Service manual HP 3582A - Page 2

riccoryder · 22nd January 2012, 08:45 PM

I'm in need of a service manual for one of these too. These likely have their share of marginal electrolytics after 30 years. They don't look so old on the outside, but add 1960 to the first two digits of the serial for the year. It never hurts to check the power supplies first although that reminds me of the old joke when a passerby asks a guy crawling on the ground by a street light what he's doing.... looking for keys is the reply. When asked where he lost them he says down the block and is then asked why he's looking where he is. The light's better! Last I checked my old HP 300A Harmonic Wave Analyzer, close to twice as old, is still working. That makes this newer stuff with proprietary chips that come and go look like a passing fad. But old or older, HP gear is great stuff.

After some digging i found a couple of bad caps, some resistors that looked like they had a hot time was replaced to.

It´s now up and running again.

It´s a very solid buillt piece of equipment will work many more years.

Thanks to all help from members of the forum.
