content: Recently I've been returning to Electronics and tinkering with a few bits and pieces. As luck would have it, at work they were disposing of some oscilloscopes and I grabbed this one.As I'm mainly using sub 100Mhz Arduino's and sensor circuits this scope is way over the top for what I need. Also, my workbench/lab is only about 1sq.m so I need something smaller that takes up less space when in use.Looking to swap for a cheaper portable LCD scope, Siglent,Rigol, etc, as I said above, 100Mhz would be fine, 2 channels. Mixed Signals support would be good but not a deal breaker. Alternatively best offers and I'll by a new portable scope with the proceeds.Has options 1F,2F and 13 fitted, not sure what they are but has RS232, GPIB and Centronics interfaces. Probably not been calibrated for the last 5 years but the battery still holds the current date and presumably the last cal data. It was manufactured in 1996.No probes are supplied with it.It's in mint condition, just a few old cal stickers around the case that could be easily removed.Pete

content: swap? Sure, i would give you Hantek MSO !!!!! ... but i'm actually honest person.When you sell it on ebay you will get for sure 800-1200EUR. For that money you can buy lot of cheaper DSOs, even MSO from Hantek (Voltcraft)http://www.voelkner.de/products/422673/VOLTCRAFT-MSO-5062B-2-16-Kanal-Oszilloskop-Digitales-Speicheroszilloskop-Bandbreite-60-MHz-integ.htmland an LA or better probes, or what so ever extra.Or even wait a bit and buy soon one of the latest Rigol 4 channel (cheap) DSO:https://www.eevblog.com/forum/testgear/new-rigol-ds1000z-and-mso4000/

content: Where about are you in the UK I suspect that scope is worth a lot more than a cheap new LCD scope!

content: or even better, sell that Tektronix on ebay and buy Hantek benchtop DSO5072P (and hack it to 200MHz bandwidth)for 270USD, then buy the Logic Analyzer Hantek 4032L for 200USD and (as it is always good idea to have bench and portable)portable Hantek DSO1062B (and hack it as well to 200MHz bandwidth) for 500USD.That's total (with UK tax, hehe) about 900EUR, i'm sure you will get 900EUR for that Tektronix.This is of course of the possoble combinations, you can really get a lot of (chinese) products for the money you canscore with this Tektronix DSO.

content: I really had no idea what it was worth, there have been a few on evilbay but they were advertised at stupid prices and didn't sell - so no help at all.Well if someones wants to swap an Agilent DSOX2012A for it I'm totally game!@Magicmushroom666 I'm in the central belt of Scotland.Peter

content: If you want to know what something is worth Ebay is helpfull but you have to click on 'completed listings' and then choose 'sold listings'. That will give you a reasonable ball park what something is actually worth.The prices equipment sellers are asking are usually insane and they don't sell that much. They all seem to think their storage room is filled with gold bars. Some are so dumb to ask three times more for a defective unit than a bad looking working unit (for which the price is still insane).. Go figure...Edit: I'd keep the scope. I have a TDS744A myself and I'm very pleased with it. Isn't there some way you can put it on a shelf or a stool? When my space was more limited I used to have my scope standing on the floor. Its not even inconvenient.

content: Those appear to sell for around $1000 US on completed auctions, at least in the US.I'd keep it. Make a second tier shelf above your workbench for it.

content: Quote from: PaulAm on May 19, 2013, 09:33:46 pmThere's no chance of that, my desk/bench is on front of a window and I have a full height bookshelf behind me, there's literally no place to locate it and be able to use it.Looking for £500 + delivery (UK only, sorry) and I'll buy a cheap Hantek + other T.E. I'll actually fully utilise.Peter

content: Please do me a favor and put it on Ebay for £1000. I'm pretty sure you'll sell it for that price! I know you got it for free but getting £1000 for free is better than getting £500 for free.
