HP3582A Audio spectrum analyser
(1/1)
cowasaki:
I have been looking for an audio spectrum analyser for 5 years.  I eventually found one I could afford at a police auction of all places.  It was advertised as untested BUT with a 90 day return warranty due to their inability to test the item so they were unable to list it as working.  As it was a 250 miles round trip I went to collect it with a carry bag containing some leads and a signal generator.  Unfortunately when I got there the device lights up with a stationary dot at the middle near the top of the screen and no text.  No amount of button pressing and turning of controls brought it to life and they looked at my dejected face and offered me a refund.  I had paid £400 for it so had to take it.  Only then did I realise that it was a refund but I could keep the faulty item as they couldn't sell known faulty goods.

So I walked away (rather staggered away these things weigh a ridiculously large amount!) with the device but it was not working.

When I got home the dot isn't now appearing either although when you switch the power off you see a flash of the dot appearing.

The device was VERY well packaged so no damage was caused on the way home.


So here I am with a faulty HP 3582A which cost be nothing.

I planned to have a look inside  and clean all the contacts then check the power supply and caps.  After that its a bit outside of my area of expertise.  Anybody on here know their way round one of these?  Anybody know someone in England that repairs them that doesn't charge silly money?  There is somewhere in the US that charges $500 for a repair, service and recalibrate package.  Something like that would really suit me.  The device is in surprisingly good condition.

I´ll try my luck here.

I recently got a HP3582a analyzer, but it came without any probe(s).

My question is, can I use "any" probe (e.g. oscilloscope probe) for this machine or do I need to find one of the original HP 10001A probe(s) that was recommended by HP at the time?

cowasaki:
It is audio frequency so pretty much anything will give you a reasonable display. If the output you want to view is BNC just use a BNC to BNC lead. For looking at an audio test point I tend to use a BNC to micro clip lead or similar. I modified Kim with a couple of pairs of speaker output post with central 4mm sockets as the originals were damaged or missing. I have a couple of those leads that have a ground and hot pair of 4mm banana plugs 19mm apart then go to a lead with a crocodile clip and a micro clip.
